Hello everyone.
This is my first post so be nice to the new guy.
I'm after an 8GB memory card that will give me the fastest xfer rates when put in a TD2?
I don't know which to choose between 2 sandisk (sdsdqy-8192-e11M and sdmsm2Y-8192-e11m) and a Kingston (sdc4/8gb). The Kingston ones states it's a class 4 device but the sandisk ones don't. Is one better than the other or is their another which wipes the floor with these brands?
Thanks for looking.
Regards,
Fru
Looking in to this myself at the mo, except at 16GB. From what I can see the 2 sandisk's you mention are both class 6 with SDMSM2Y-8192-E11M having a read speed of 15MB/s as oppose to 10MB/s for the other one.
see:

and

for your class ratings... happy hunting, let us know which one you go for.

Bit more reading done.
I found this article on a US website in which the author implies they have information from HTC themselves that their mobile devices host bus will only run at SDHC class 2 speeds. I've emailed HTC myself to see if they will shed any light on this.
Turns out from what I am reading that as in most things, the speed is that of the slowest link so if the host is class 2 then whilst a class 6 card will work, you may not get the best throughput or achieve a lesser throughput than you would otherwise expect from the class of the card.
I then tried the Kingston memory website which lists the Diamond 2 in its list of devices they have memory for. Now, they say that for 8GB (my chosen capacity) a class 4 card is what I should go for and for Galvinize's chosen capacy (16GB), a class 2 card is recommended. I've emailed Kingston to see if they will shed any light on this.
I'll post back if I hear from HTC or Kingston.
Regards,
Fru

The Diamond 2 spec sheet says it's sd 2.0 compatible so anything higher would be wasted on it.
Hi Root Beer.
SD 2.0 is SDHC which allows storage over 2GB.

Good work Fru,
After thinking this over last night, I came to the conclusion that a class 2 device would be more than adequate anyway, what possible use is there for being able to read and write at 10MB/s ? I can see the need for high end photography, where you need to punt a large amount of data on to the card in as short a time as possible in order for the camera to be ready for the next shot. But for your phone, where the data on the card will be largely static (MP3s, programs, Pictures, documents e.t.c) I see no need for the extra speed. It will take a little while longer to copy the content on to the card to start with, but after that I doubt you will notice any difference.
Cheers Galvinize
"But for your phone ... I see no need for the extra speed"
I am quickly coming to that conclusion too. Apart from high end photography which, I would imagine rules me out, and maybe video, the only real IO streaming I think you may do is with GPS. Even then you'd have to be going at jet aircraft speeds.
As the TD2 isn't available to me yet (T-Mobile in the UK), I may wait to see what HTC and Kingston come back with. If nothing then I'll go for class 2 and upgrade to 16GB like you.
Regards,
Fru
FYI a reply from HTC (for what it's worth):
Dear valued HTC customer, Thank you for contacting our Customer Support Center. We are dedicated to providing you with the best quality service and answering all of your questions and concerns. You recently wrote us about an issue that you have encountered with your HTC device. Regarding your enquiry for the memory card to your device, your Touch Diamond 2 device is capable of using the Micro SDHC memory cards over 2 GB. We will recommend one of the bigger memory card brands like ‘SanDisk’ and save the receipt. Thank you once again for your continued patronage. Best regards, Europe customer support team HTC Corp.

I've responded asking them for the class information of the host bus rather than the memory specifics.
Now we're getting somewhere ...
Dear valued HTC customer, The touch Diamond 2 can support all 3 classes. That means the device can take class 2, 4 and 6. Class 6 would be the fastest one of them all. Thank you once again for your continued patronage. Best regards, Europe customer support team HTC Corp. Global Service Division

I think most 16 GB cards are class 2 at the moment. At least, lokking at ebay and some shops, they either mention class 2, or no class at all (which is likemey class 2 too). I did not find a single 16 GB card of class 4, let alone class 6.
I think 16 GB are a little bit too new to be available in the faster variety yet, it should change in the months to come.
I've ordered 16GB Kingston microSD card today...it's written as Class4. We'll see...monday is the shipping day, tuesday is receiveing day...i'll test.

Very interested in seeing the outcome of your tests: I have seen a report ( http://www.ldlc.be/critiques/PB0008...tateur-sdhc-garantie-10-ans-par-kingston.html - it's in french...) from a guy who ordered a Kingston 16GB class 4 card and ended up with a class 2. So I guess one have to be extra-careful even if the card is advertised as class 4 (the online shop is a big one and has good reputation, so is Kingston....getting a class 2 for a class 4 was not expected)
Got a 8GB Scandisk from carphonewarehouse on friday, class 2, working perfectly.
Just got my 16GB Sandisk Class 2 ... not yet plugged in...just waiting phone to finish charging up
Not bad, cost me £24
Where from dude? that cheap!!!
i would buy the sandiks ultra cards.
the 1,2,4 and 8GB are real class 6 the 16GB is a class 4
normal sdhc are class 2.
im waing for the 16GB class 6

I DONT, i got the 8GB class 2 (for now).
but for that litle extra (say 5 a 7,5 euro extra) you can have a class 6.
lets say more BANG 4 your BUCK. More SPEED is always NICE.
Sandisk 8GB didn't work out of the box
interestingly, when I put in my new Sandisk 8GB card in the Touch Diamond 2, it was recognised only fleetingly (for about 0.5 second) and then disappeared from both File Explorer and settings, memory. Only after I formatted the card in a laptop was it recognised and usable in the Touch Diamond 2. There were some Sandisk files on the card (prior to formatting...)
I'm waiting for my new pro2 and I'm planning to buy a 16Gb memory card for it...but I don't know which brand has the best reading/writing speed...
I mean...are there any "class 6" card?
It's better a Sandisk or a Kingston?
I found some sites that offer 16gb micro-sd class6
http://www.supermediastore.com/adata-turbo-series-16gb-class-6-micro-sdhc-with-adapter.html
http://www.newegg.com/Product/Product.aspx?Item=N82E16820211378
Not sure if they will ship internationally. Hope this helps

Running fine with sandisk 16gb class 2.
Class 2 is enough for usb and internal memory from tpII
don't waste money in this case. You don't notice any difference at all.
I have a SanDisk 16gb class 4. This one is good enough. The compromise between speed and money

That appears to be a class 2 not a class 6, may be acceptable to many, but in the context of this thread it's not comparing "apples with apples". Having said that it's still a good price for a 16GB card.
Gordon
Class 2 is okay - The price is perfect
Class 4 is good - The price is good
Class 6 is perfect! - The price is horrible
--> Class 4 is the best tradeoff!
Just got a transcend class 6 16gb microsd for rp 640,000... thats approx equivalent to USD60. I can get a cheaper brand VGen for approx USD 50.. but then, for an extra USD10, you get a more reliable storage card with lifetime warranty....
at the end of the day, the reliability of the data being stored is the most important thing to consider... if the price doesnt differ much, then ALWAYS go for better quality one... this would be my rule of thumb when purchasing things usually... things have different prices for a reason, and usually its the quality...
as with speed, i dont think it matters a lot... a good indication is if you can watch movie with a class 2, then data transfer rate is good enough...
I went to a well known IT mall in Singapore today to get a micro SD card for my Rhodium.
Class 4 16 gb micro SD retails for 73 Singapore Dollars versus 26 singapore dollars for a 8gb micro SD Class 4. (Kingston)
I opted for a simple 8gb and wait for the prices to come down slowly. I don't think I will be using lots of space for making videos and photos. And if you want to view any videos, convert them to the screen resolution helps.
Just got a Transcend 16gb Micro SDHC Class 6 off a local store here.. to me the price at $123 is still ok.. oh well.. the price I pay for an early adopter... I can very much remember the time I pay $100+ for a 512mb full sized SD.. haha..

To some like me, I just want a bigger capacity and speed.. I already had the 8gb Micro SDHC class 6 like a year a ago. May be cheap now but I never regret get it then.. besides, I fill up these card pretty quick and they are not about Videos nor Audio files. Audio/Video I do it on a dedicated player.
I already fill up till I left 4gb on my Transcend 16gb Micros SDHC I got yesterday.

Where I bought my 8Gb Class 6 for £9.89
Hi for info I recently bought my TP2 memory card for £9.89 at
http://cgi.ebay.co.uk/8GB-CLASS-6-M...AsAccessoriesQ5fMemoryCardsQQsalenotsupported
Works a treat and noticably faster than my 4Gb class 4! It works perfectly with my TP2.
As a note my 4Gb class 4 drops off from the device occasionally, the 8Gb never!
Using the Class 4 card the TP2 struggles to play a 640 x 272 131kbps Video and 131kbps Audio 25fps 700Mb DIVX AVI movie, No problem with class 6 using TCPMP on the device.

hi!
is there any difference between 16GB class 2 Sandisk and 16GB class 2 Kingston?
I own a class 4 Sandisk 8GB and a class 4 Kingston 4GB and I don't notice much difference!
but I can buy a class 2 Kingston 16GB for about $52 and I was considering it (but it's a class 2...) or I can buy a class 4 Sandisk 16GB for about $75...
will I notice the difference (all I do is sometimes transfer mp3 or a movie to the card through Active Sync)... I don't use it as a Pen Drive or so...
I really need a new card since my 8GB is almost full!!! and I have to carry more than one!
BE AWARE
Don't buy transcend 16GB: they don't suppor power resume after sleep mode.
Example:
Create a windows media player music catalog placed on storage card
and activate random player.
Connect your htc headset and start listening music.
As soon as your device will go into standy/sleep mode with player running
on the next song the music will stop as your sdCard will disappear from system.
Modifying PnpUnloadDelay (and similar) doesnt help nor disabling sd-power-safe.
Tried 4 trasdendend with 3 different pro2: the same problem.
Bought a sandisk and resolved
So be aware!
Does the same count for Transcend 8GB Class 6 MicroSD's?
I can get one for 23 euros. The SanDisk costs 2 euros more for 8GB but Class 4.
Is 8GB enough for me anyways: navigation program, some photos, programs and videos. Because the SD's are getting bigger and bigger; I imagine that programs are too? Maybe 16GB would be a better investment then, or should I not seeing the use I make of it?
Got my TPII today so I am figuring it all out Thanks.
i want to buy a class 6 card in the uk, sems theres no 16gig here would settle for 2 X 8 gigs to hot swap one with movies on one with the rest of my stuff
any suggestions for good quality class 6 8 gigs in the uk
i was just wondering what the best class 6 microsd card available in the uk is. i know people are saying a-data is very good but i cant seem to find one on the uk. i have tried a google search but the websites are american and prices are in dollars. help would be much apreciated. thanks in advance
edit: i currently have a kingston 8gb class 4 sd card but i dont think tis good enough to run the latest hero builds. also does using an adapter to transfer files effect the speed and is it better to use a usb adapter instead of a card adapter?
This site seems to have some good prices: http://www.7dayshop.com/catalog/def...rwords=microsd&go=SEARCH&comp=&page=1&sort=3d . They are apparently not the quickest shop.
One guy on that site claims the transcend class 6 is slower than his Kingston class 4, but gave it 4/5 and bought a second... I think the Kingston is quite quick for a class 4 anyway, the rating system is a little wacky and no-one verifies it.
ok thanks. does anyone have a transcend 8gb card that can comment on the quality/speed?
http://www.amazon.co.uk/SANDISK-MOB...1?ie=UTF8&s=electronics&qid=1251474559&sr=8-1
I thought this was quite cheap for a well known brand.

I was in the exact same situation as you, live in the UK and couldn't find an adata card that everyone was raving about. I settled on a Transcend 8GB Class 6, and I have no complaints. I have *never* had the card show up as damaged, and have never had any issues with apps2sd and swap. The speed is decent too, never had a write speed bellow 6mb/s. I'd go for a transcend if I was you.
I bought two 8 GB class 6 microSD cards on eBay that are being sold as "FOR NOKIA E90 N95" and so far they're both working great (one is in my G1 and the other in friend's BB Storm).
I did read/write tests and they are not fake as far as I can tell and the price is really good, compared to branded products.
ok thanks guys. i seem to have found a website that sells adata memory card in the UK but im not sure if if they are reliable or not so i might stick to the transcend and sandisk ones.
I want to know what class of micro Sd I will buy for my X10mini.
There are may advantages using a class 6 or class 10 micro sd for video?
Can anyone tell me what is the transfer rate supported by this smartphone?
I bought a cheap class 2 16gb card, and haven't had any problems with it - music and video plays fine.
Remember the class rating of a card is the minimum data rate, rather than the maximum - mine manages 6mb/s transfer rates.
X10 mini from Rogers
a 16gb micro sd card came with my X10, i'll receive my x10 mini from Rogers in few days, i wonder there's any micro sd card come with it?
Unless you're doing HD video, a class 2 card is fine. I bought an 8gb class 4 card for around $29 from a computer store. Don't go to somewhere like officeworks as you'll pay $35 for a class 2 card.

Ok, so if I find a class 4 at a good price well, otherwise a class 2 works well.
But what is the max. speed of data transfer (to SD supported) by the X10?
i got a 16gb on ebay class 3 or 4 for about £15 ( Around double in dollers) works just FINE
Finally I have the solution to the problem
Many thanks to everyone for the answers, and I can also give a contribution (to me and others ) because today a technical staff of Sonyericsson wrote me that the X10 supports a micro sd maximum class 4, every other class does not produce benefits in terms of speed, are supported but will not be used at their maximum speed.

Be careful with e-bay as chinese sellers sell hacked 8 and 16GB cards, which in reality are 1 gb card which report themselves as 8 or 16 (and are marked 8 or 16).
I have bought a Kingmax 8GB class10 on ebay and it's very very good !
My x10 mini pro came with a 2gb card, doesnt say wich class I assume its class 1 or 2 as most stock ones are, from what Ive heard android phones dont take advantage of anything above class 4 from the OS at least, but you can speed up music and file transfer by getting a class 10 and using ur pc card reader to fill it up faster =) wont give you any better performance for phone tho..
I have a extra Sandisk MicroSDHC (8 GB) card. Works fine.
Sold my standard 2gb one.
i have kingston sd class 4gb and i buy it for 9 EUR from store and is working normal
I've bought Kingston 4GB MicroSD and it wasn't working. Maybe it should be useful to make a thread of compatible SD's.

Be interesting to learn the maximum throughput. Meaning sequential may be capped at 4 MB/s, wonder how fast it performs doing random R/W.

Anyone tried PATRIOT 16GB Micro SDHC 2v1 Class 4?
i heared that there are some problems with sd cards class 4 on mini pro, but class 4 and 6 works perfect
Im using Kingmax 8GB class 4 card. working just fine..
I just bought a 16GB PNY Class 10 card from here: PNY 16GB
Cheap at £17.99 and seems to work really well. SD Tools says it is writing at 9.3MB/s. My previous Transend 8GB Class 6 wrote at 6.5MB/s. Seems quicker when using camera: ready to take next shot sooner
My new card!
I just got a Transcend 16GB Class 2 for around $25! Class 2 doesnt make that a difference. I have set 3072 kb as the card buffer in MIniCM6
I had problems with a Kingston 16gb sd. Replaced it with a Sandisk 16gb, works fine now.
Hi. I read that a few of you have bought wintec micro sd cards from newegg.com. I was wondering if you had any problems with this card. The reviews on newegg seem mixed. I particularly want to buy the 16 gb class 10 microsdhc. Does this card work in the transformer? Any help would be great. I want to spend my money right the first time and not waste any on unreliable cards. Thanks

Not sure about the Transformer (yet... still waiting for mine. Hopefully tomorrow), but I bought one for my Motorola Atrix. After formatting it in the Atrix, it worked for a little while, then my Atrix said the card was unrecognizable. I had similar issues when I put it in my Nexus One as well. Using it in the SD adapter with my PC or camera doesn't seem to have the same problems.
I find that a class 4 card is good enough for most things. Heck, I use a class 2 card on my Archos 5 Internet Tablet to hold movies, and I have never seen it stutter. I just bought a class 4 card in anticipation of my Transformer.
If you want a faster card, get one from a reliable manufacturer. But I really don't think you'll need it.
I've been using the 32GB Wintec class 10 in my EVO for months with zero issues. It's fast too...makes a very noticeable difference when viewing pictures in the gallery. I was a little nervous after hearing other people's reviews, but it's been great for me. I make sure to backup fairly regularly though, just in case.
My 1st wintec 16gb class 10 would constantly get corupted in my epic and wouldn't be recognized in my laptop at that point. I formatted it numerous asy and the results were always the same. Rma'd it and just got the replacement today. Will load some things on and give it a shot with files I won't care about losing if it goes down.

I couldn't wait for a decent 16GB Class 10 microSDHC card to get back in stock, so I ordered two of these Wintec cards from Newegg yesterday. I know there's a chance they will crap out soon, but I thought I'd take the chance since I'm impatient. I wish the A-Data ones would come in stock sooner.
Sad part about the Adata ones is they're usually a class or two slower than their rating. So their class 10 is probably about a class 6 where Sandisk ones usually outperform their class. I have a class 2 32gb Sandisk in my Samsung Epic and have had no complaints about speed or reliability.
Im using one right now in a stock unrooted TF. But when I tried to root it , it always corrupts that card!
I bought two Wintec 16GB Class 10 MicroSDHC cards and they BOTH didn't work. I couldn't format them and I had problems recognizing them on the TF and computer. I'd stay away from them.
Wintec class 10 16gb microsd works fine with my TF.
Faster than my other class 4.

Buying a MicroSDHC card
Class has to do with the speed of data transfer to your “microsdhc card”.
You may want to be careful of that particular memory card (Wintec Class 10 MicroSDHC) on Newegg, Located at ...... Alot of very bad reviews for this item. It has a very high failure rate. 1/3 of the cards fail, become nonfunctional after a very short time, loose data, lock up, etc.
For a couple dollars more you may want to get SanDisk or Kingston memory. I have been using their memory products for many years. Both have an excellent rating and warranty. I also find it hard to believe that you can get a real, reliable and functional Class 10 memory at that price. Usually a Class 10 memory retail about $175.00 $190.00 but can be bought for $ 75.00 to $90.00 dollars.
People who usually use Class 10 are photographers, for speed of image transfer to memory and less time waiting between shots, and heavy duty graphic users that have a lot of transfers to do with large files.
For example for a real Class 10 memory:
NewEgg:..... $89.00
Amazon:..... Kingston-MicroSD-Adapter-SDC10-16GB $82.00
Example for Class 2 memory:
SanDisk 16 GB microSDHC Flash Memory Card $23.85
Example for Class 4 memory:
Kingston 16 GB Class 4 MicroSD Flash Card with SD Adapter $32.84
Class 2 or 4 will do just fine for your Asus Transformer.
Just go with Sandisk. Even Class 2/4 Sandisk cards will be fast enough. Cheaper brands just stick a class 6/10 on their cards and buyers will eat them up. But real-world performances will show you that they're definitely not in the same class as Sandisk cards.
