Is there a final word on the compatability of the Hermes with 4 and 8 micro sdhc cards
mpc
I have emailed HTC about this. I also dropped in a question about when they plan on releasing a ROM for the TyTN (rolls on the floor laughing.....deliberatly didnt use the acronym).
According to the FAQ on thier site there is a limitation in the OS :
What is the maximum SD card size compatible with my device?
For Win CE 2003 =>General for SDIO is 1GB.
For WM 5.0 => SD Card is 4GB and Mini-SD is 12GB

also they claim there is no limitation whatsoever?!? But this could be for ANY of thier devices so i emailed them anyway:
Does my device have a maximum size limit for CF/SD cards?
No, as long as it's a standardized memory card (SD or CF) and a device is designed according to those standards then it will accept the card.
EDIT:: DO NOT TAKE THIS AS PROOF OF SDHC COMPATABILITY (mrvanx)

current windows mobile 6 roms have the sdhc drivers installed too... anyone willing to buy one and try it out... as us australians always get everything 3 to 5 months later i cant try it ... plus bad experiences on scam-bay so not trying that avenue...

Its a shame nobody has tried (or atleast posted thier findings), but hopefully a reply from HTC would help us out. Cant see why they would withold this info.
I would take the plunge and buy one but the 4GB ones are still pricey (for me) so I would have to REALLY need it for something before forking out the cash.

Responce from HTC
It looks like it is simply a restriction in the drivers by MS according to HTC:
Dear Sir,
I am afraid to say the SDHC memory cards are unsupported by any of our handsets, to offer support for these memory cards Microsoft will need to update the drivers for Windows Mobile 5.0. We have tested our handsets with standard 2GB miniSD cards which work fine.
Thank you for your enquiry, Should you have any other problem, please do not hesitate to call us. Your Local number can be found at

What does that say??
SDHC support has been available for quite some time now if the presence of an SDHC driver in the registry is anything to go on (I've seen it in the AKU2 ROMS). However whether it works or not is a mystery waiting to be solved....
With the "0" setting i did not loose my card today after 4h of operation...
That is for a 2GB Sandisk (not SDHC)
But anyway on SDHC:
I have gathered the following info on the net:
---------
SDHC (Secure Digital High-Capacity) cards are flash memory cards with a minimum capacity of 4GB (gigabytes). SDHC cards provide removable memory for compatible digital devices including cameras, camcorders, PDAs, MP3 players and more. Secure Digital refers to a specific format within the flash card market. SDHC cards are designed for devices that are compatible with the SDHC 2.00 specification. Products designed exclusively to support previous SD specifications 1.0 and 1.1 will not be able to utilize SDHC cards.
The growing demand for high-capacity flash memory springs partially from the increasing use of high-definition video and high-resolution digital photography. SDHC cards meet the challenge of these demanding products not only by providing ample storage but also by introducing a new feature: classifications of data transfer speed (DTS). Consumers can get the best performance value out of their digital products by using flash memory cards that support the device's highest standards for data transfer speed. The SDHC specification 2.00 calls for cards to be classified according to the minimal sustained DTS as follows:
* Class 2: minimum sustained DTS of 2MB/sec
* Class 4: minimum sustained DTS of 4MB/sec
* Class 6: minimum sustained DTS of 6MB/sec
SDHC cards are classified to guarantee a specific sustained DTS. This potentially saves consumers money, as flash cards are priced not only according to capacity, but also to speed. For example, if a product's maximum DTS is 2MB/sec, dishing out extra cash for Class 4 or Class 6 SDHC cards would be a waste of money. Conversely, devices that can utilize the 4MB/sec or 6MB/sec DTR will perform significantly better with Class 4 or Class 6 SDHC cards, respectively.
Secure Digital was forced to create a new specification for SDHC cards when the previous specification topped out at a capacity of 2GB. This occurred previously when SD cards hit the 512MB wall. The new 2.00 specification should last a bit longer, as it allows SDHC cards to reach a maximum capacity of 32GB. Secure Digital is so-named because of its ability to protect copyright content through digital rights management or DRM. Because of this, it is a favored flash memory format in the audiovisual industry.
SDHC cards are about the size of a postage stamp. Insiders expect them to be available through several different manufacturers by summer 2006, and prices will vary. Before purchasing, be sure your device is compatible. There are several card formats available on the market, and devices are proprietary. If a device manual does not list SDHC cards, or state it is "SD specification 2.00 compatible," the device cannot utilize these cards.
--------------
This info does not seem fully accurate as I saw on the web a 8GM Micro SDHC...
Anyway we should validate what class the Hermes support, but I would think that Class 2 may be the the maximum speed for this device?
We should investigate further.
Is the pinout for SDHC card THE SAME as SD?
I remember I've read somewhere that pin count is greater.
I'll search on wikipedia
Did some searching, found this thread:
http://forum.xda-developers.com/archive/index.php/t-284628.html
the SDHC driver is indeed in the active driver section in the registry in our devices, but as the last post indicates, it's in microsoft's terms and doesn't stand for what we are looking for.
So in short, really pitty, but it looks like we're out of luck.
Edit: Before anyone says it: i KNOW it's a trinity thread, but there's a Hermes user in there!

let me introduce myself... i come from Wizard but it was stolen from my hands at knife menace Im near of getting a hermes... I see that this big Brother of wizard has the same F#$n **** on their Card useless incompatibilitie... maybe in certificates... but here i saw less less people buyng things without read jajaja... Its nice to see people that get info after do stupid things like buy a 4GB SDHC...
Its Sad to have a great Machine without this capacity on cards...
I did it today, I have a Hermes 100 (I-mate JasJam).
To cut a long story short:
http://forum.xda-developers.com/attachment.php?attachmentid=58063&d=1194986892
I am currently running a 8GB SDHC Micro card.
Mate, if you updated your rom with a cooked rom you wouldn't need the patch as most wm06 and ALL wm6.1 roms are already sdhc compliant.
Just make sure you have Hard SPL V7 installed before upgrading so if something bad happens you at least have a chance to fix it...
Cheers...
Well I read my post and...
Absolutely right Ultramag has the reason!!!!!
SDHC microSd can be read on HERMES the last word to say it is yessss as ultrmag said the newer BUILDS ROM has the patch!!!
So enjoy your 8gb MicroSDHC and we will wait for 16 GB hahahaha i hope so...

From Mobile-review.com:
"Kingmax has announced a storage card microSDHC capacious of 4 GB. This is a record for this standard, says the company. Until now microSDHC cards carried 2 GB maximum.
The cards comply with SD 2.0 specifications. They feature 127X or 19.1 Mbps (write) and 150X or 22.5 Mbps (read) speeds. No doubt, the cards will be in demand for multimedia mobile phones and other portable electronics, should the price be adequate. Unfortunately, the company hasn’t provided the info on the release date."
But do our Tytns support SDHC anyway?
No the Hermes does not support SDHC.. too bad, my 2gb is almost full!

Has to be seen I think, don´t know of any standard (non-SDHC) 4GB microSD card, do you?
SDHC info from Sanddisk:
What is SDHC? SD High Capacity (SDHCTM) card is the new SD™ memory card based on the SDA2.00 specification, introduced by the SD Card Association. This new SDA 2.00 specification enables SD cards to reach higher capacities - 4GB-32GB*.Because SDHC works differently then standard SD cards, this new format is notbackwards compatible with legacy SD format host devices. More SDHC compatible devices are expected to be available in the second half of 2006. To ensure compatibility, look for the SDHC logo on cards and host devices (cameras, camcorders, etc.)Compatibility with SDHC 4GB: 4GB SDHC cards can only work with SDHC compatible host devices. To ensure compatibility, look for the SDHC logo on the packaging. Please check with your device manufacturer for their current/future supported SDHC devices. What is Class Speed Rating? The SD Association has created and defined 3 speedclasses to help you identify speed and performance capabilities/minimum requirements of SD/SDHC cards and the host products. The SD Speed Class Ratings specify a minimum sustained write speed for SDHC cards (Class 2: 2 MB/s; Class 4: 4 MB/s; Class 6: 6 MB/s*). You can look for the Speed Class Logo to identify the performance class of your memory cards and host devices. NOTE: SDHC, the SDHC logo and SD are trademarks.*1 megabyte (MB) = 1 million bytes; 1 gigabyte (GB) = 1 billion bytes.
SDHC will go upto 32gb in a SD card size
Wow
There would definitly be some software upgrade required to use SDHC card for Hermes.

Don't you have to format anything larger than 2GB in NTFS format.
I think this device can only read FAT16. Might need a ROM upgrade

No, SDHC Cards are formated in FAT32, so it isn't so hard.
I just formated my 1GB microSD Card with FAT32 and I was able to read it on the Hermes. So this should be no problem.
Just go to your local dealer and tell him, that you will buy it if it works with your PDA. Normally this is no problem. I tried severall MemoryCards this way in former times.
I think it's worth a try...
BrainWashed: what rom are you using?
Can you PM me the name of the driver?
Thanks!

If you have an SDHC card, you may try a solution from here: http://forum.xda-developers.com/showthread.php?t=293556
Please report the results!
Actually, I've looked through my registry, and found all the registry settins that are installed by this CAB already there. Also the driver file required (SDHC_SC2410.dll) is sitting in my \Windows directory.
So... SDHC should work on Hermes out of the box...

I am not sure if this are micro are not. When i go to newegg, MicroSD and SDHC are different categories. Thanks for any help.
UllSang,
The links you posted are for Secure Digital (SD) card sizes. The Hermes uses microSD cards. These are much smaller physically.
Both SD and microSD have the high capacity version (SDHC and microSDHC).
MicroSDHC cards work on the Hermes only with the latest cooked versions of WM6.
The second one is a standard 8GB SD card, afaik there isnt an 8GB MicroSDHC just yet.
We know 4GB microSDHC definatly works (you need a recent version of WM6).
you do realize those are sd cards right?
oooppss. . .sorry.. didnt realize sombebody has made the correct point.
hey mrvanx sir. you might want to fix the link on your ROM: part of your signature.. (or is that just a teaser? )
Hmm. I had a feeling that it was not microSD. Good think i asked before i bought one. So can anyone point me in the direction of a 4GB microSDHC? Thanks a bunch.

Man those 4 GB SDHC cards are soo expensive. i can get a few 4 2GB for the price of one of those.

SanDisk today announced that it is has begun sampling 6 and 8 gigabyte (GB) microSD High Capacity (microSDHC) flash memory cards to major phone manufacturers and mobile network operators (MNOs) for testing and evaluation. The new cards are ideal for the growing number of feature-rich multimedia handsets that bring together phones, music players, hand-held computers, digital cameras and more. An 8GB microSDHC card can store more than 2,000 digital songs, or more than 5,000 high-resolution pictures, or up to 5 hours of high-quality MPEG 4 video2.
Retail release of the cards and availability to phone manufacturers and network operators are planned for later in 2007.

They also sell non SDHC.. So it's a buggy crap, but some people claim it works. I tried one made by Dysan, actualy it was 3.9GB. It worked in STR TRK, until I reached the maximum. Then all data was like lost.
MrMiguel: rather get a 1GB SD card. Not sure for what you need so much space. I have 2x 1GB SD and it works fine. If I know I will make demos, I change the card in my phone.

It's such a pain to change out the MicroSD cards in this phone, though. That is the point of having the largest one you can get.
Obsolete
The hardware requirements are different for SDHC cards. The 8525 actually has a SDHC card reader (32GB), but WM5 only supported regular SD (2GB max). When people cooked WM6 ROMs for the 8525, they made sure to include new SDHC drivers, allowing up to 32GB cards.
I'm not sure what type of card reader hardware the 3125 has, but it seems likely it is only a regular SD reader, as the 3125 is more similar to the 8125 than the 8525. The 8125 only has a regular SD reader. Even if the 3125 does have hardware support for SDHC, it doesn't seem all that likely that there will ever be a WM6 ROM for it, as HTC isn't releasing one, and the developer community here doesn't seem that motivated.
The limitation is not on the OS at least as far as reading 4gb is concerned. As long as the card is not sdhc. I have a 4gb sd card fully loaded with 3.5gb+ data and programs. My htc universal has no problems reading and writing to it. Very fast, too. Even my old Toshiba E800 sees all the circa 3.98 gb in both read and write mode. There are even 8gb non sdhc cards out. I have not tried them but people who report that they work just fine. I have not seen a transflash 4gb card that is non sdhc, but I have no doubt it exists.
"Jozer99 . . . The hardware requirements are different for SDHC cards."
The HTC Universal was shipped as Non-SDHC, however the latest ROM's have been providing SDHC with the existing hardware. It seems to be more an issue of the drivers, not the hardware.
any news?
I still have a 4GB card lying around, I'd like to use it. Is it possible?

I would also like an answer to this question. Here is a link that claims it does:
http://store.wmexperts.com/content/accessories/7-128--2803.htm
I have an 8525 running this 4GB card but it is running WM6 and someone said that is the only way to get 8525 to read this card. If true that means WM6 would also be req'd on the StrTrk. I'm interested because my daughter wants a decent Cingular phone that will store 4GB of MP3's. If it does I will buy her an 3125.
Click to expand...

Cingular 3125 is pretty crappy for listening to music. Buy a simpler MP3 phone. The headphone jack on the 3125 is proprietary, and the included earbuds are awful. The music player is Windows Media Player, which is somewhat buggy, occasionally skips and crashes.
The hardware requirements ARE different. HTC shipped many devices with SDHC card slots, but with OS support for only regular SD. However, some older HTC devices actually DID have SD only slots, so it is not possible to use SDHC cards with them. HTC hasn't really released device specs, so the only way to know for sure will be to port WM6 and see if it works.

Please tell us: what kind of card? SDHC or non-standard SD?
This is what HTC.wiki says:
microSD slot NOT capable of SDHC; maximum theoretical capacity is 4GB, which has been confirmed through several reports from HTC, wherein they stated the phone has been "tested up to 4GB". Though user reports of this are not present, 4GB non-SDHC microSD cards are rare as well.
http://www.htcwiki.com/page/Qtek+8500+Specs?t=anon
so maximum capacity is 4 GB THEORETICALLY!! They have no user reports till now! What do you say?
Found this cab for SDHC for smartphones:

Micro SD 2 GB
I am using 2 Gb micro SD in my Dopod S301. Its working fine. I have yet not seen a 4Gb micro SD. If you have one I think you can use it !!!
I tried the SDHC Support Kit on my 3125 and it didn't work. And still haven't found a 4 gig non SDHC card yet. hopefully someone will come out with one soon, or a hack that would allow an SDHC card to work.
Nokia MU-41 4GB microSD card
The Nokia MU-41 4GB microSD card appears to be non-SDHC, as the pictures of it do not show HC on it, even though sellers of it advertise it as SDHC (see here for example) - but ad blurbs often say "High Capacity" - well, yes, it is High Capacity, but maybe it is not Secure Digital High Capacity, and there is a difference that is more than just FAT32 formatting, as can be seen by trying to use an SDHC card in an older card reader on a PC - won't work - got to use one that is SDHC 2.0 compatible.
The Sandisk website has a good explanation of the differences:
"The SD High Capacity (SDHCTM) card, miniSD High Capacity (miniSDHCTM) card, and microSD High Capacity (microSDHCTM) card are the new SD™ memory cards based on the SDA 2.00 specification, introduced by the SD Card Association. This new SDA 2.00 specification enables SD cards to reach higher capacities: 4GB - 32GB*.
Because SDHC, miniSDHC, and microSDHC cards are recognized by new SDHC, miniSDHC, microSDHC host devices differently than standard SD, miniSD, and microSD cards, they are [FONT=Tahoma,Tahoma]not [/FONT]backwards compatible with legacy SD, miniSD, and microSD format host devices. Standard SD, miniSD, and microSD cards are forward compatible with new SDHC, miniSDHC, and microSDHC host devices.
Legacy SD/miniSD/microSD host devices and SD/miniSD/microSD cards (up to 2GB) are FAT 16 file system compatible, while the new SDA version 2.00 file system specification defines a SD FAT 32 file system for the new SDHC/miniSDHC/microSDHC host devices and cards.
Be aware of non-SDA 2.00 specification compliant SD 4GB, miniSD 4GB, and microSD 4GB cards on the market. If these non-compliant SD/miniSD/microSD 4GB cards record data in a SDHC host, and are then used in a legacy SD/miniSD/microSD host, issues and problems may occur. File system incompatibility, data corruption, and potentially you may actually lose the data/pictures. In addition, if these non-compliant SD/miniSD/microSD 4GB cards are inserted into a legacy SD/miniSD/microSD host device, the host device may not recognize/utilize the card as 4GB, and it instead may read as a 2GB card. If the SD/miniSD/microSD 4GB card does not have SDHC/miniSDHC/microSDHC on it, it is not SD 2.00 compliant.More SDHC, miniSDHC, microSDHC compatible devices are expected to be available in 2007. To ensure compatibility, look for the SDHC/miniSDHC/microSDHC logo on cards and host devices (cameras, camcorders, etc.)"
Based on this, I am hopeful that a 4GB microSD that is NOT labeled with the SDHC logo (like the Nokia MU-41), may work with older devices such as the StarTrek. I know there are 4GB miniSD cards that are non-SDHC, because I have one, and it works fine in my 8125, where an SDHC card will not.
Ok, so from my research, the 8GB Micro SD is not yet widely available or even on the shelves (correct me if I wrong). But, according to the various sites I've looked at these size cards are well on there way to being released.
I know the new standard of SDHC SD card are available in 8GB and possibly above, but I have now got a Hermes, so wanted to try going higher in Micro SD. Presently I use both a 2GB and a 4GB Micro SD, depending on what I'm needing to store.
Size wise 4GB it great as options for storage are vast.
But I wanted to see it there was any further news as to the new 8GB or higher that I'd read somewhere?
Having looked on line I could only find the following:
6GB Micro SD
==========
Pre-ordering only?
1: http://www.mymemory.co.uk/memory/SanDisk/6GB/Micro/SDHC/Card
= SanDisk 6GB Micro SDHC Card £69.99
8GB Micro SD
==========
Pre-ordering only?
2: http://www.mymemory.co.uk/memory/SanDisk/8GB/Micro/SDHC/Cardhttp://www.mymemory.co.uk/memory/SanDisk/6GB/Micro/SDHC/Card
= SanDisk 8GB Micro SDHC Card £99.99
Since upgrading the Hermes ROM on my phone to WM6 which was purely to allow it to use the 4GB Micro SD I had bought (I swear by SanDisk as have NEVER had a problem with them in over 5 years of assorted SD cards)
Am going to keep looking over the next few weeks and would be interested in any feedback if any others have found any news about higher capacity versions.
I have no idea if WM6 will be able to read higher than 4GB but my guess would be a resounding YES! on the grounds of what I have a feeling is WM6 full? SDHC support. whereas WM5 on the Orange version of the Hermes 'SPV M3100' had only partial support and can only recognize 2GB sized Cards.

PS: if this post is in the wrong place or out of date can a mod sort it out and remove or move it. Many thanks. Just wanted to share my interest and findings on these Micro beasties thats all.
You accidentally posted the 6GB page, if you change the "6" to "8" in the URL you'll get what you meant for the second post.
Wow thanks for those links can't wait to get my hands on 8GB of freakin memory! I'm very impressed with MicroSDHC and am so glad the Hermes can take the always (albeit gradual) increasing card capacities, without new hardware needed.
Take that, iPhone! (don't worry, i love you too)
I found it very difficult to get a 4gig microSD card in the US. I keep seeing these cards in the UK but they don't ship here. Does anyone have links to any companies for even a pre-order.

The six (6) GB link was intentional bud. I have researched "above and beyond" the 4GB size. Happened to find the 6GB link on same site so added it as I didn't know if like myself others were also unaware of this specification.
Cheers anyway.
You missed his point, your 8gig link is incorrect, it links to the 6gig ad.
Wow, 8G! Wish I had known that before splashing out on an 8G Zen MP3 player.
Thanks for the spot!
Are you sure the hermes does support the micro sdhd?
I wrote yesterday to htc to ask what is the max size of microsd that hermer support, and the follow is the answer:
[....]
Good morning
The max size card your device supports is 2GB. It will not support HC (High Capacity) memory cards. Please see our recommended product below:

Teorically an microsd reader could be support the HD format through a firmware update...
Ps: What is the difference betwen micro SDHD and micro SDHC?
From italy,
Mattia
MattiaRs-- There many threads in this forum about people using sdhc cards in their hermes with the newer builds of ROM. You gotta search and read.

When a representative from Orange looked into this on my behalf, he also was told me that HTC was only recommending that the Hermes be used with 2GB Micro SD cards, as that was the limit they (HTC) would guarantee.
When I first tested cards out prior to a firmware update to WM6, the above was indeed true.
However, my Hermes now runs WM6 and uses a 4GB SDHC Micro SD Card on a daily basis without ever having a problem.
I have no idea if this will be true of higher spec cards such as the 6GB or the 8GB or even anything higher, but I feel confident that it will. But that is just my opinion as until tried and tested its down to guesswork whether or not other card sizes will be recognized.
PS: you asked what is the difference between micro SDHD and micro SDHC?
The answer is that I have NEVER heard of Micro SDHD. To me that is a High Definition tag and not one that refers to any card type.
I've only ever known SDHC.
Even Google comes back with: "Did you mean SDHC" Maybe others know of this type of card?

You could walk into a verizon store anytime and pick up a card, if you wanted. Other people have been able to order 4gb cards-- you could, also. READ!!!
Transcend 4GB SD with Exec loses data randomly --please help.
Hello there,
I read you people are using 4GB SD without any problems, you might solve my problem.
I am using one on my Exec with WM6,(ROM 2.02.02,Radio 1.15, Protocol 42.51.P8, no ext rom) and facing a weird problem.The card loses the data for no apparent reason.The folder viz. My document has just been emptied and I lost my all ebooks--150 MB.
The file explorer shows the card contains 776 Mb data while the 'Resco explorer' shows 1007 Mb,in setting-memory-storage card it shows 1007 Mb,but it actually has only 776 Mb data, so I have lost 150 Mb data permanently and 300 Mb storage space on card!
This is the THIRD time it has happened and on previous occasions I had the card replaced.I am fed up with this problem,is it the card itself or the Exec or the WM6 or the ROM which is causing this problem?
Is there any way to retrieve the data and the memory lost from the card, for I think it is there and it just hidden somewhere...I hope.
I am not a techie,(medical doctor--using Exec more as a PDA than a communicator)hence the lengthy description ,thanks in advance,sorry for the intrusion.
bye.
sorry for the hastles your having
I wish I could help you further but apart from what I have read relating to the Hermes I can't.
I would hazard a guess and say that it sounds more like the Operating System / ROM which perhaps is not handling the card properly.
Best if you put up a new post on the main board and ask for help.
I hope you get it sorted as I know from my own problems similar to your missing card data how really annoying this problem is. I do know that I have had two SD card made by transcend. I used them for 6 months without a hitch. I put movies and files on them both for University and work use and used them in my previous phone which was an English version of the Prophet (Orange SPV M600)
Point is that in my own experience, Transcend are indeed a reliable brand or storage card. So it doesn't sound like a card problem in my opinion. Perhaps you may new to look at updating the ROM? I have no knowledge of your phone model "Exec" so can't help. But as I said best if you ask for help on the board. Maybe on various boards if you've had no luck already. Someone may have previously owned an Exec and might be able to shed some light on this problem.
Kalya-- You need to post your problem on the Universal forums, not the Hermes. There, hopefully, you will get the help you need. Different models react differently to various things. May you find your solutions...

From what I've been told, Sandisk made a deal with Verizon so they are the only approved suppliers in the US for one year. You can buy the 4GB miro SDHC card from them or any Verizon distributor (even Circuit City). However, they are more expensive than Amazon...

Ijust got my Sandisk 4gb sdhc today... woohhhoooo
Has anyone seen this? http://tinyurl.com/ybz2qfd
man that's crazy, although the 64's won't work with g1, I think its expandable capacity is only 32gb, but that's still big! Not sure of the class #'s on these bad boys, but I'm sure if there aren't any 6 or 10 class versions available yet it won't be long!
EDIT: nevermind, they're all 32's.....the 64gb has something to do with flash or whatever, IDK
32gb is the addressable limit of the SDHC standard.. when 64gb cards appear they will be SDXC, which means no current hardware can use them. Awesome.

Strange you should say that....

As I'm a newbie, I can't post external links.... but apparently CAN post links where "http" have been changed to "hxxp". I spotted this link earlier today, from Morgan Computers - a BIG hardware-clearance company in New Oxford Street, London. £51 for a 32Gig SDHC card.
" The 32GB SDHC memory card is German made, leading edge technology at its best! It also comes with a lifetime manufacturer warranty.
The 32GB SD Card offers high storage capacity with a write speed of 10MBytes/s and a read speed of 20MBytes/s. It is ideal for new generation digital camera and other applications with SDHC cards slots.
Compatible with All SDHC devices
32GB stores approx 1200 x 10MP Photos, 545 Hours of MP3
May be in Eco Friendly Bulk Packaging
*Please Note: SDHC cards will only work in devices that are compatible with the Higher SDHC Specification cards"
I'm going to invest in one of these for my (new!) Desire - my two G-1's will have to continue to make-do with 8 Gig Sandisk TF cards.
You let us all know how that works.

I have two 32GB SDHC's, one is class 2, the other class 6.
The class 2 works but it's insanely slow and it consumes a lot of battery due to the extra hot time required for reads and writes.
The class 6 is extremely fast and doesn't cause noticeable battery drain.
So am I correct in assuming that the higher the class number, the faster the performance & lower the power usage?

Meh. Until there's a PAE firmware released for the device. Like how a 32bit OS can only handle 4GB RAM until you enable PAE. (In windows, you can simply "turn it on", in linux you need a kernel with a PAE module enabled)
PAE, or Physical Address Extension, should allow for a 52 bit limit on physical memory but only supports a 48-bit virtual address space. 4 × 10245 bytes, or 4 Petabytes and 256 × 10244 bytes or 256 Terabytes, respectively. (What that means is, if the hardware doesn't support 52 bit addresses natively, then they highest capacity that can be reached via PAE is 256 Terabytes through virtualization.)
What does that mean for an android device? A PAE Kernel Module could be created to allow for addressing of more than 32 Gigabytes, how far past 32 Gigabytes? That I don't know. I would assume at least somewhere in the realm of 128-256 Gigabytes. I doubt there will ever be a MicroSD card at that capacity though. By the time we see affordable solid-state storage as small as MicroSD with a capacity over 64 Gigabytes it is unlikely that MicroSD will even still be around, and I doubt anyone will still be using the G1 anyway at that point. We're talking another 4 years or so, making the G1 an antique by technology standards.
tl;dr version: Once 64GB cards are affordable enough for it to be practical to put the time and effort into a firmware mod (kernel module,etc) for an android version of something resembling PAE, you can expect -someone- will figure out a way to enable 64GB usage in the G1.
I think we're gonna see faces like this: all the time, when it comes to electronics industry... I can still remember my first Intel 486 with a few MB HDD!
Man one of these would be nice!
For me 6gb is enough..
For music etc i have a mp3 player!
Here we are 2 years later, 256gb micro sd cards are just starting to appear on evilbay.
Also USB thumbdrives that can handle up to 512gb cards
