What speed is the 2GB stock MicroSD card?

What speed is the 2GB stock MicroSD card the HD2 ships with? (Just to know)
IS Class 2 fast enough? I have a 16GB class two that I'd like to use, but not at the expense of performance on the phone, or problems, etc.
Anyone?

Class II is enough for a phone. Dunno the speed of the inserted one - guess it is class II. I'm using a class II 16GB mSDHC from Toshiba since more than a year and I never faced any problems.

Here I have done two micro SD benchmark using sandisk microSD reader:
SanDisk microSDHC 2GB Classe 2
SanDisk Mobile Ultra microSDHC 8GB Classe 4
The Ultra version has twice the speed of the stock one.

Yeah, that may be right and it could be faster when you copy some files to your phone or pull it down of it. But nevertheless the phone does not need more then class II, because it won't be able to exhaust it.

Even when recording video?

[Q] What memory cards are you using to run android from?

Hi Guys, I'm currently testing the MattC 1.5 build from a generic 4gb microSD card i had lying around and it works pretty well, but i was thinking of buying an 8gb Sandisk Mobile Ultra card to replace it. I would link to the car but i'm not allowed A quick search on google/ebay should bring up the card i want.
Do you think I would notice an improvement in speed with android running from the card?

If your current card is a class 2 and the 8 gb is a class 4 or higher than yes, tou would notice a difference.

I use Sandisk 16gb sdhc and no problems with running android-of course only proper wm rom.... Not sure which class is the card

my current card is a Class 2 4gb Sandisk, for £17 i might just get the new card and see how it goes. Would you expect an increase in the score on the Quadrant benchmarks?

Sandisk mobile ultra sdhc 4 gb class 6

are these cards definitely class 6 as i have seen various sites saying they are only class 2 but much faster than the class 2 minimums?

I use a Sandisk ultra sdhc 8gb class 6......working great

16gb stock card that came with my tmous hd2, so im guessing its a class2 but everything runs smoothly tho.

Hi,
Well, I use since last week a SanDisk 32 microSDhc class 2. Pretty fast in data transfer.
Read somewhere that the class 2 of this 32 GB edition can be compared to class 6 of older micro SD cards.
Had the standard 2gb microSD before, which was sold with the HD2.
Have no issues of speed with SanDisk 32 microSDhc class 2, when it comes to running Android and transfer data.
Recommend it!

Download SD Card Speed Tester from Market
and test your real speed. Run it three times on each card.
I have Class 2's that are 2's. I have the original 16 gb Class 2 that rates at six and a class 4 Sandisk that rates at a 9. You never know till you test it. Also have a Class 6 that rates at a 9.

8 gig kingstone class 4.
i got a 4 gig class 6 micro sdhc, but i can't notice a difference in speed big enough to compensate the loss of 4 gigs (lots of songs stored).

[Q] Most Reliable SD Card to Run Android

Might sound like a strange question, but what would you suggest getting for most stable Android run. I've had a SAN DISK 16GB but it would always get corrupt and formatting (tried using SD Formatter/windows tools/phone) would only fix the problem for short time.
So which of the following in your opinion is the most reliable choice:
1. SAN DISK
2. PATRIOT
3. Kingston
4. ADATA
5. Transcend
6. Lexar
7. SONY
Also, what class (2,4,6 would be nice if someone could explain whats best and generally what it means). As well as capacity (whether it affects reliability)

No one buy the kingston class 4 4gb card, does not work well at all! I trashed it lol

i got a Class 10 Patriot card, works well, really well

Transcends 8gb Class 6!
Never had a problem with it

Hi, I am using transcend 8Gb card. I dont find any problem till now.

RiData 16GB Class 6
Been using it for 2 weeks. No issues.
Write & Read transfers are averaging 9mbs when transfering backups to and from.

Kingmax 8Gb Class 6, not bad

Don't buy transcend 8gb class 6 card in any situation, it has really bad power drainage problem in every build, after I swapped it with my friends verbatim class 4 8gb I have top 1 % per hour drain in standby, believe me.

Any way to check faulty micro sd?
Thanks everyone for the input, seems like I've either got a faulty SanDisk card or doing something wrong here. Are there any tools to test whether or not my 16Gb SanDisk micro sd is faulty or possibly corrupt... By the way, I got it off ebay for $20... seems fishy, although it came in original packagin brand new.

...
German TakeMS 4GB Class6, works like a charm...

Transcend 16gb class 6 runs Android with no hiccups at all and the transfer rate is blazing fast

Samsung 4Go Class 4, low battery drainage, performs like a class 6 card. Original style (grey coloured).

Battery consumption
Battery consumption on Transcend sucks if you want long battery life use sandisk or best by my tests 8gb class 4 Kingston.

i have 4 different sd cards kingston 4 gig class 2, 2 sandisk 4 gig , and a class 6 transcend 8 gig...and i always get better results with the stock card

Sd card don't have jack sh*$ to do with battery drain. As far as cards go, it don't matter. Just pick one. There all the same regardless if someone says this one is faster because it's a class 6, or 8. I have a class 2,4, and 8. No difference what so ever. Even though its written on the class 8 at a higher speed.

Any idea on why sometimes I find non-removable random symbol files on my SD? Does this indicate corruption?

German TakeMS 8gb class 6 extreme fast and stable.

Memory Cards (SDHC)

Hi Guys,
I have a strange situation going on here with my micro SDHC cards. I have an 8gb Sandisk card class 2 and I just bought a 16gb Duracell class 4 card as I wanted a bit more space than 8gb for my desire HD (to be arriving soon).
Anyway the 16gb card arrived today in the post so I was bored and decided to do some speed tests on the 2 cards just to check. The class 4 card wrote at 4.1 mb/s which I presume is what it should do...right? How ever the class 2 card wrote at 13.5 mb/s!! I tested it several times with large amounts of data (using the H2testw program) and it kept getting the same results.
So it lead me to think that there is something wrong with my class 4 card (or its a fake). It does write at 4 mb/s but that is the bare minimum and surely it should be doing better? I got it off ebay and am now aware of the extreme amount of fake cards on there.
Anyone with a little experience on the matter care to offer me some insight?
Btw I will be using my phone for pictures and 720p recording so I want a fast card...but after this I am just confused.
Thanks

Your card is just fine. The class of a memory card just tells you how slow it isn't, not how fast it can get.
Class 2 - Minimum of 2 MB/s performance.
Class 4 - Minimum of 4 MB/s performance.
Being a class 4, a minimum 4 MB/s is fine and passes the class 4 classification. But a 13.5 MB/s for a class 2 is great!

in my experience larger cards tend to be slower in real life situations anyway, i have found issues using slower cards so tend to stick with a minimum of class 6 (but then your class 2 exceeds that spec )

I don't know. But one of my friend using class 4 transcend sd card and he can play 720p videos. While i can't using Sandisc class 4.

Thanks bdw. I purchased it and it's working fine. Write speed is 9mbps and reading at 11-13mbps
Will try diff cache value.

Class 6 gives good performance. Having no problems since 3 months.

I use 32GB class 10 Lexar.
No problem at all.

I've been using a class 10 16GB TOPRAM card for almost a year, with no problems.

I use a Kingston Class10 16GB since a week ago and it's working fine so far. 9.1MB/s write and 19MB/s read on 2.3.6

Thanks for starting this thread
Im going to order a class 6, 8 gig samsung card for my defy from letsbuy.com
@darshan - bro, what is you say ? how are you finding your class 6 card in defy? how about 720p playback and HD gaming?? Is there any issue with day to day usage, like with camera app and something? Does it hang? or does it goes in to READ ONLY by any chance??
Btw, Im running on stock 2.2.2 without root.
Thanking you in advance
