does anyone know the max transfer rate for SD Cards in the DESIRE?
Is it limited or dependant to the SD card?
I wonder if it is useful to prefer a CLASS 4 card (4MB/sec) for Class 2 (2MB/sec)
Well, I have a Sandisk 16Gb class 2 and it's slooowwwwwwww... under 1Mb/s for small files.
I found a Kingston 16Gb class 10 and I've bought it, I'll receive it by the end of the week and I'll tell you if I find any difference.
wow C10
how much did it cost?
Probably about a 100 bucks Hor judging by eBay prices. Gonna camp here and wait for benchmarks before buying one.
Yep, and because I'm french it's a hundred euros
I know, it's probably too much for that kind of device (class 6 would probably be enough), but I just want to try out
Here are the results using J Benchmark 1.0 on the phone to test my current SD card :
Parameters : Data size = 10MB, Buffer Size = 2KB
Write : 1,7MB/s
Read : 2,4MB/s
As you can see, it's around 2MB/s which complies with the class 2 logo.
sorry about pop this thread but it is related,
I want to buy a better SD card with a higher class, so I contacted htc and ask them up to which class desire supports , that's the answer:
hank you for contacting our Customer Support Center.
With regards to your inquiry,
Kindly note that the compatible Micro SD Card with HTC Desire is class 6.
Thank you once again for your continued patronage.
Sincerely,
Karim
HTC
so , I saw that there are some desire owners who has a higher class sd card,
and my question is does it has a faster writing rate or is it an overkill?
thx, Nitzan

Hello,
Now that Froyo more or less came out and apps will start having Apps2SD function, it's time for a MicroSD upgrade.
What I want is on-phone performance - that running heavy 3D games on SD would perform as smoothly as if it was on internal memory. Is there a general consensus on what brand/class would suffice, and what is overkill? I have no concern over data cable transfer speed, as I'm pretty sure the phone will limit the speed much before the SD card does.
I'm looking at this Sandisk 16gb MicroSDHC Class 2 for $35 after shipping:
http://www.amazon.com/SanDisk-Flash...ref=sr_1_1?ie=UTF8&s=pc&qid=1275145563&sr=1-1
Anyone know if this would suffice?
Past threads have always went on tangents about good brand vs knock offs, how class is important vs. a marketing ploy, etc etc. Has a general consensus been reached in the xda community over what is sufficient but not overkill for onboard performance? Perhaps people who have already ran App2SD and use games and videos a lot have some input.
Thanks
I have a Top Ram 16 Gig class 6 and I think I paid about the same as you looking to pay for a class2. I also have a class2 that I have had for over a year. I used to use it in my blackberry. It still works and it is made by one of the cheap manufacturers.
Argh, I'm suffering from chronic SD corruption. So I'm in the market for a new chip. Think I'll spring for a 32gb this time. What's the latest on one that's both compatible and fast? And cheap too, that would be nice, links appreciated.
Considering that due to the amount of RAM the N1 has your main apps will be loaded already so card speed is not a significant factor, unless you use lots of different apps on a regular basis.
A faster card is beneficial mostly for the time i takes when I am loading up new music and possibly vids if you use it for that
This is the first 32gb MicroSD card I have seen "In Stock" Pretty expensive for a class 2 though.

Micro SDHC is a standard that supports up to 32gb. Of course it can handle it just fine.
I run a 16gb Class 6 in mine, works fine
bewar ebay, there a lot of folks selling fake cards. They even read as what they were sold as but then fill up mighty quick............
The class is not needed I don't think
I have a class six and have been running games on it from sd for 3 months cant tell a bit of difference. I run linpack from sd and it works fine too!
the only real 32gb card is found here., http://www.sandisk.com/products/mobile-memory-products/sandisk-microsdhc

I'm running a 32gb Sandisk Class 2 in my Nexus as of last Friday. No problems (apart from a looooong time to refresh the media library after resyncing my music).
You can not get a genuine 32GB Micro SD card for US$40.
A good class 2 card (2MB/s) will offer you the same performance as any other class in your phone.
The limitation is not the speed of the card.
Buy a brand name card with the capacity you require and be done with the complexity.

I don't know too much about transfer rates but basically what you're saying is that a a brand name class 2 card will be just as good as say a class 6? I'm in the market for a new SD card as well, and the class 6 cards are much more expensive. I'm wondering if they're worth it.

No, in a phone they're not worth it at all and people who say so are either selling snake oil or are embarrassed because they've paid for one and are foolish for doing so.
The best I can do just at the moment is this:
wikipedia said:
In applications that require sustained write throughput, such as video recording, the device may not perform satisfactorily if the SD card's class rating falls below a particular speed. For example, a camcorder that is designed to record to class 6 media may suffer dropouts or corrupted video on slower media.
Click to expand...

The Nexus, like probably every other phone out there, is a) not typically used for high rate sustained write activities and b) is designed to write to class 2 media to begin with.
If you have a large, highly fragmented sd card higher speeds will help. This of course is easy to avoid in the first place.
Get a higher capacity, class 2, brand name card for the same money and you're away laughing.
NB - If somebody waves a magic wand and all of a sudden the Nexus can record video at 1080p at a high enough bitrate then perhaps my advice would be invalidated... but don't hold your breath for that to happen...

Thanks for the info man! I was obviously misinformed, you just saved me a bunch of money
so just curious. now that CM 5.0.8 comes with 720p recording, would a class 2 still suffice?
I am also searching the web recently to look for a cost-effective high vol microSD. My finding is: don't 100% trust the "class" specified by mfr. I used ATTO Disk Benchmark to test two 8G microSD that I have: Transcend 8G Class 6 and Sandisk 8G Class 4.
<Transcend Class6> Write: 6-10MB/s Read: 16MB/s
<Sandisk Class 4> Write: 14MB/s Read: 20MB/s
From similar test results on the web, it seems that Sandisk uses to under-state the performance of their card. Finally I get a Sandisk 16G Class 2 for my N1, and here is the test result with the same setting:
<Sandisk 16G Class2> Write: 7MB/s Read: 20MB/s
Although Sandisk only specifies it as class 2, it actually performs like a class 6.
I suspect the importance of the speed of the SD card too, coz I think the write speed into ROM, should be way slower than 6-7MB/s (correct me if I am wrong ^_^)... If the speed of v2.1 w/o app2sd is acceptable to you, then v2.2 with 6-7M write speed card should be logically fine with you.

huh that's interesting. i just might pick that up from amazon then..
I Dont think fragmentation makes any difference to write speed, these are not mechanical devices like hard disks.
Also defragging is pointless and shortens the life of the card by increasing the number of writes.
I want to upgrade the stock 4 GB microsd in my unrooted htc desire to a 16 GB microsd card. My question is can I copy what is on the 4 GB microsd and transfer them to the new 16 GB microsd and just insert it in? would all programs work?
many thanks for your help.
Yet, the apps are on the phones memory and the info is on the SD card so you can just copy across.

I agree - I had lots of problems with an unbranded 16GB card. Eventually ebay closed the seller down as there were so many complaints. I did get my money back via paypal. I finally bought a branded 32GB card - costly (EUR100!), but I love having so much space for my music / video.
Is there really a need for anything above class 4?
My HTC Desire came with a sandisc 4GB class 2. I want to get a larger card, but never had any reading issues with the class 2, and music and video played off it with ease.
I've seen the following item here, which is for a class 6.
http://www.amazon.co.uk/Transcend-m...r-TS16GUSDHC6/dp/B001PLIG5Y/ref=cm_cr_pr_pb_t
Anyone got one of these?
I've just bought the 'ultra' version of Sandisk's 16GB microsd card and I am very impressed with it so far.
Personally, I always feel that it is best to stick with the tried and trusted brands, and sandisk products have always been excellent for me
I just bought a 16GB SanDisk class 2 from amazon and it writes on average at 5MB ish
-------------------------------------
Sent from my HTC Desire
I thought the class number i.e. 2 meant the read and write speed 2Mbps. Therefore class 6 would be 6Mbps. If you have a class 2 and get 5Mbps then that is pretty impressive.
The Class of the SD card is simply the *minimum* sustained write speed on a card which is completely unfragmented. So, a completely blank Class 2 card should always be able to write large files out at least 2mb/s, but can easily be faster.
My 16gb Sandisk Class 2 reads at 20mb/s and writes at 7.5mb/s - well above the Class 6 minimums.
Regards,
Dave
my 32gb is a class 2 and i have zero issues with streaming video or music from the card, i expect when i root that apps will not be an issue either. plenty of read write speed.
the higher classes are for devices that require a higher bitrate for recording such as mini hd recorders and such.
Im running a SanDisk 16GB Class 6 and its like Lightning!
Hi,
This may be a silly question for some but i've searched around and i still cannot find a definitive answer anywhere with regards to micro sdhc cards being used in the samsung galaxy s. If i was to purchase a micro sdhc card am i going to need some form of adapter? I only ask because most places i shop around only sell micro sdhc cards.
It was my understanding that the galaxy s only had a micro sd slot which is what is currently confusing me.
Thanks.
it supports up to 32 GB of microSD
anything larger than 4 GB = SDHC support
Galaxy S supports Micro SDHC.
(Allgamer basically said that, just in a slightly roundabout manner).
I'd like to know (please), whether the device can perform all functionality such as record hd and playback 720p movies over dlna from a class 2 card? I want to order a sandisk 16gb card, but would save the pennies on a class 4, if a class 2 performs well.
you could still get a class 6 16GB cheaper than getting a Class 2 16GB Sandisk, if you buy from other brands like Transcend (excellent), Adata, OCZ, Kingston, etc....
If it helps, I'm using an old class 6 Transcend 8GB. Bought for a micro DVcam (hence the need for class 6) last year and think it was around £10 then - possibly cheaper now?
You can get a 8 GB SDHC from DealExtreme.com for < $20 any day of the week.

I am currently using 4 GB Micro SDHC card with SGS.It is my old phones (HTC HD Mini) Micro SDHC card and it is working great.
I just bought this Wintec 16GB class 10 from Newegg.com... now whether it's an actual class 10 that's to be determined cause it's in the mail. But for $30 you at least get 16GB.
anyone try a-data 32gb class 10?
I'm curious if anyone try a-data 32gb class 10?
half the price of other 32gb cards.
the reason I ask is many folks report issues with hd cams.

not that i know of, so far all the confirmed legit SanDisk 32Gb has been Class 2
some places advertise they have Class 4 SanDisk 32Gb microSD but.... the picture and the price listed are those of a Class 2
some people have confirmed the Class 2 SanDisk 32Gb microSD can write 4Mb/s but that was on a new empty disk test
i would like to see some test done on 60% full 32Gb Class 2 SanDisk microSD to see if it can sustain a Class 4 write after half full, being a Class 2
check this review link http://www.testfreaks.com/blog/review/review-of-kingston-class-4-32gb-microsdhc-card/

How ?? A 720p video at maximum quality usually takes around 1.5 ~ 1.8MBps, so a Class 2 (2MBps guaranteed write speed) in theory should be quite sufficient, at least with my Class 2 cards I haven’t had any trouble recording 720p video.The Sandisk 16GB Class 2 I have can be written to at a minimum constant speed of 8MBps (has around 4Gigs of Data on it already). And the Nokia branded (not sure about the actual brand) 8GB Class 2 which I got with my previous Nokia phone can be written to at 4MBps + (has 7Gigs of Data already). So IMO as long as you go with a name brand you should be able to get more than 2MBps writing speed which should be enough for 720p video.
You might get better speeds when transferring large files to your phone, but how often do you do that ?? And if you do that over Wi-Fi or Bluetooth like I mostly do, it won't matter at all. Spending on anything above class 6 (e.g Class 10) IMO is a total waste of money. I use a class 6 on my DSLR to record 1080p video, haven't had any issues with it so far. So I hardly think Galaxy S can exhaust a Class 6 card, or even a branded Class 2.
video is a secondary use
i use it mainly for applications and data transfer (portable hard drive), the faster the better, the less noticeable lag, and speeds up Titanium Backup quite considerably

The recent batch of SanDisk microSDHC cards (seen here in Brussels in Media Markt and Fnac) has Class 2 marking changed to Class 4 (8, 16 and 32GB). They have exactly the same packaging down to part numbers. That's mine for example: http://i37.photobucket.com/albums/e62/ping_ling/android/microsdhc.jpg

Hey guys, I just got my sensation yesterday! YAY So happy with it so far.
But can any of you guys recommend me which micro SD card is the best for sensation? I am looking to get 32GB.
I heard it will make the apps lag if the SD card is not very compatible with the phone? Any idea guys? Please help me. Thank you.
someone here mentioned that sensation only reads/writes upto class 4...so i guess it wouldn't really matter if u get a higher class
but u may end up using the card for something else like a camera. so it doesn't hurt to get a higher class
So what is the highest class available now? What brand do you recommend? Thanks for the reply!

Complete rubbish.
The official specification for Class 10 is a read speed of 10MB/s and a write speed of 10MB/s.
The official specification for Class 4 is a read speed of 4MB/s and a write speed of 4MB/s.
(sorry if that was stating the obvious, but I don't think some people realise)
The benchmarks for my Lexar 32GB Class 10 card in my Sensation (using "SD Tool" from the Android Market) are a read speed of 21.4MB/s and a write speed of 8.3MB/s (taken from an average of 4 tests).
So the Sensation doesn't quite meet Class 10, but it's much faster than Class 4 and 6.

Can someone tell me which is the highest class of SD card,which will b fully used by Desire S
And is there noticeable drop in performance of the phone between full 16gb and 32gb?

Imo class 10 is the fastest SD-Class.

Class 10 is the fastest micro SD card for now, but the htc engineer does not suggest that we use it because it could lead to some unknown error.
Class6 is enough.
32GB is supported by Desire S.
The purchase of the brand, Samsung is not a good choice because their indicators are virtual.
That's my personal opinion,just for reference.
I moved from a 16g class 4 to a 32g class 6 card, everything runs smoothly and didn't really notice any drop in performance.

Sandisk 32GB class 10 or Kingston
When you test a lot of roms (as beta tester), different tools or apk skinned, you need some space and faster w /rw
You could find this class of sdcard not really expensive, you must search a little.
i think people are exaggerating with these SD card classess.. my advice is that class4 and a quality brand should be enough for everyone. in fact you can have a class10 card from a noname manufacturer and the actual speed is same as class4 and a good brand. good brands are all that actually manufacture the chips. they are toshiba and sandisk/samsung. if you buy a sony, nokia or similar, you also buy those mentioned before, only rebranded. there is much written about this on the web, but in general: if you can't afford a 16gb class10 sandisk and they are trying to sell you same spec kingston for half of this price, it does mean something!
