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.

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.

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

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.

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...)
what class of card runs the various android builds quicker with touch hd memory card reader
1. class 2
2. class 4
3. class 6
just looking a definitive answer so android users please vote and post make or were bought, date bought
thx everyone
the higher the class the faster the card...
i.e. a class 6 has a guaranteed transfer speed of 6 mb/s, while a class 2 has only 2 mb/s
or i dont get ur actual question...
I'm looking to upgrade to a 16gb card. Does it matter what brand or anything? I see tons of different cards on ebay.

well if you have the money don't buy one from ebay look on play.com or somewhere as the ebay ones are probably no where near as reliable, i have always bought of ebay personally and never noticed any issues but i know they are cheapo ones so will probably not last very long, and don't always hold the full 8gb
Read speeds!!
if im right class refers to write speed 2mb 4mb 6mb
surely the read speed is more important for running android via sd on card reader of touch hd
what is the microsd card reader hardware spec of the touch hd, if anyone knows
i managed to buy a class 10 16gb kingston microsdhc on amazon £34, whether it arrives as class 10 is a different story tho.
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.
Hello,
I want a new MicroSd HC Card for my Hero.
After doing some research on the internet, I am confused...
Some people say, that it is senseless to buy an expensive class 6 or 8 card for the phone, because it can not handle the extra speed a card with a higher class has.
Currently I own a Toshiba Class 6 8gb Card,
but this one has not enough space.
I thought about buying 16 or 32gb.
Do you have any recommends for me?
I have a class 4 16GB SDHC card for my Hero (it's a sandisk one for a reputable retailer, NOT eBay). when I perform speed tests on it, it says it is a class 2, which is the exact same class as the 8GB SD card it replaced.
Some class 4's can perform better than a class 6, it seems to be luck of the draw. Apparently the CLASS refers to the read speed I believe, Class 2 minimum 2MB/s. I've probably got that totally a*se about face...
I am told the hero can handle 32gb cards, only reason I bought a 16GB was because the Hero was replacing a 16GB iPhone 3GS. I've had no problems whatsoever with it. Another user (on the forum) has loads of issues with lag from his 16GB SDHC card. No reason whatsoever. Just seems to be hit and miss.
I WOULDN'T BUY A SD CARD FROM eBAY THOUGH!!!
I got a 16gb sdhc class 6 from adata - have been using it nearly from day one, can't say I noticed a change in performance from the 2gb card that came with the Hero.
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.
