Lots of grumbling about the microSDHC that Samsung is shipping with the GS4G, which does carry a "Class 2" stamp on it, but just how fast is it?
Tests were performed using a Lenovo T410s, Windows 7, ChkFlsh v1.16.1, and an Elago microSDHC Nano II USB reader. Tests were against the raw device.
Tested were
Samsung OEM 16 GB -- 14.9 MB/s read, 7.5 MB/s write
Transcend 8 GB, Class 6 -- 14.8 MB/s read, 11.1 MB/s write
AData 8 GB, Class 6 -- 14.9 MB/s read, 11.1 MB/s write
Given these results, I'm finding the all the bashing and reported "slowness" of the card a little harder to give a lot of weight to.
Even if the write speed is a little slower (or even a lot slower), that the read speed is comparable suggests to me that most things (like launching an app from /media/) wouldn't be significantly sped up by a Class 6 or Class 10 card. Maybe I'm missing something because of potential read bottlenecks in the reader or host USB controller that wouldn't be present in the physical device, but jeeze -- all of Angry Birds can be read off the card in a second.
My class 10 will be here Friday, I can let you know how that compares to the class 2 that came with it.
I benchmarked both of my cards in CrystalDiskMark (64-bit) in Windows 7 64bit. The cards were both placed into a Micro->Mini adapter. Here's what I came up with. Left side is Samsung 16GB, right side is my Transcend card.
As you can see, for random 4K block performance, the Trasncend beats out the Samsung by a good amount. Not sure how often the phone actually encounters that type of usage. Also, I don't believe the numbers on the bottom row matter for the phone. That's with a Queue depth. I think it only matters on a PC using NCQ (Native Command Queuing).
Random write performance is pretty horrendous for both cards.
The card that came with it keeps giving errors when I try to copy the partitions to my new c6. Might be my reader but this card doesn't seem very good. This could jave been the best phone on the market if it had a flash and a few gigs of internal storage. Not sure what theu were thinking.
Sent from my SGH-T959V using XDA App
better late than never, here are my results:
Class 2 card that came with my SGS4G -
Write: 3.3 MB/s
Read: 13.0 MB/s
Class 10 Wintec 16GB:
Write: 13.0 MB/s
Read: 14.2 MB/s
Although, on the Wintec class 10, I did see write speeds above 15 MB/s at one point.

Hi Community,
Does the class of a SD card really matters?
Info:
Using HTC Magic or see my sig
Using CyanogenMod 5.0.8.
Using Apps2SD
Using a 8GB ScanDisk class 2
and this morning when I try to play a game which is loaded onto the SD, not internally, my phone hanged, and followed by very sluggish response.
So I rebooted my phone, and when it was done, my SD card got corrupted. I tried to reformat and it won't. I used BOTH my phone's and computers/laptop's reformat function to do it and it won't work.
Thus, I guess I am left with a dead SD card.
Community, please tell me, does a class of SD card really matter for Apps2SD? I mean I did my research and their are 2 sides to it, some claims that ScanDisk cards are good enough, others suggested the need for class 6... Which is oh-my-god-so-expensive.
I thank anyone for the upcoming response.
Cheers,
JokerAce

As with all things computer, faster is better. I'm using a SanDisk 8G class 2 myself. Yes, apps 2 SD on a class 2. It's working for now, but I'm pretty sure that it's because I have a CDMA Hero. I haven't had many issues, other than my photos taking forever to load and one time that it locked up and I had to pull the battery. I'm looking at getting a class 6 8G real soon. I've seen them in the $20-25 range on eBay.

I guess we are better getting a higher class of sdcards. Thanks.
Yes we are. Class 2 works, but it's a bit slow for today's devices. I really thoght I was doing good with an 8 G, but the speed of R/W is a factor, especially with apps2SD.
From Wikipedia: http://en.wikipedia.org/wiki/Secure_Digital
Speed Class Rating
The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. It is equal to 1 MB/s (8 Mbit/s), and it measures the minimum sustained write speeds for a fragmented state
The following are the ratings of some currently available cards:
* Class 2: 2 MB/s
* Class 4: 4 MB/s
* Class 6: 6 MB/s
* Class 10: 10 MB/s
So theory stands - the faster the better (and more expensive!)

Inasmuch as a high speed card is better, at what speed are phones usually pulling/pushing data around at the moment?
I'm currently in the market for a 16/32Gb card for my SGS and this has made me curious on whether or not to consider Class 4+, as somewhere along the line the speed of the card might be irrelevant and the depth of my pocket will make its presence known.
It has been claimed (I think over on the CM forums) that the G1 is incapable of reaching speeds higher than Class 6.
That would be consistent with the state of the art when it was released.
In fact, I would expect that the newest round of phones coming out right now are the first that can handle Class 10. The cards have just been hitting the market lately.

Fantastic, thanks Gino. Seems that Verkkokauppa is a good source here in Finland (just getting used to living here....UK ex-pat).

A 16GB class 10 card for €104 is a big tag, but directly in line with speed....can find a 16GB class 2 in supermarkets for a fifth of that or thereabouts ;-)
Must shop around. I'm sure that a microSD card isn't onerous on shipping costs.
Hey, I know that there's been some threads around but from searching through them it seems most haven't been commented on since last year, so I was hoping to see if there might be some change in opinions etc since then.
I'm in the process of buying a HTC Desire, and while I love the flexibility of Android, I can see myself getting annoyingly held back by low internal memory.
So my intended solution was to eventually root my phone when I have a spare moment, and flash the StarBurst ROM, since Data2SD seems to do a better job at forcing apps to install onto an SD card compared to App2SD (correct me if I'm wrong - newbie here) -- I know that I'd still have to install some widgets etc onto internal memory.
SO: my question is: What size of card would be good? And will I need to consider a Class 4 to be able to make use of Data2SD / App2SD functions?
There's an approximate $4-5 difference between a class 4 4GB + 8GB microSD card on eBay (and obviously, a class 2 of these two will be cheaper)
- I'm happy to pay for the larger card, provided that the extra 4GB are likely to be put to use (ie, I'm not entirely sure how much of a card I should reserve for apps to have room for a decent collection in the future)
Hi!
I am using a 16GB class 4 from SanDisk. I have 15GB fat32 and a 1GB ext partition with Oxygen 2.0 and Data2SD. Absolutely no lags at all, just fine. Class 4 is good enough. You won't set the best result in benchmarks, but I personally don't care about benchmarks. As long as everything is going smooth i'm happy.
Size is a choice you have to make yourself. 1GB for apps is enough for me. Music and stuff on the fat32 partition. It depends on what you want.
I hope this helps.
1 gb for ext partition (data2sd) is more than enough and rest for fat32 (sd card) so size is really up to you but 4 gb wasn't enough for me. You should be more concerned with the card speed. Maybe instead, of ebay pay little a bit more and get the genuine fast card. I'm happy owner of a-data 16 gb class 10 working smoothly on StarBurst. Be careful of chinese fakes on ebay.

Yeah, I heard about eBay fakes along the way. This is the type of card I found through ebay SanDisk 4GB Class 4 (can't link directly due to being a newbie on here, unfortunately), it says its coming from US from a "dz-tech" seller.
- So if I need to stay away from eBay, should a google search along the lines of "8GB class 6 microSD" suffice for finding a reputable dealer?

Thanks for that what exactly do you mean by setting best results in benchmarks? I mean, I don't mind if the card doesn't score the highest in speed ratings, but I'm assuming that you're referring more to the fact that a class 4 is fast enough to let me run apps from the card through the phone smoothly?

I mean that if you run a benchmark, you will probably get better results with cards that are rated with a higher class. So with a class 6 (or 8 or 10) you will get a better benchmark result. But, my point is, a class 4 card is good enough to use for data2sd and that stuff (as used in starburst rom) You don't need a very very fast card. Your phone will run smooth with an class 4 card, saw it with my own eyes.
Oh, I almost forgot: I think you should buy your card in a real (web)shop, not from ebay. No offense but if you buy on ebay you never know if you get a good card. Especially with this data2sd-thing it's important to have a good card. But that's just my point of view.
Anyway, good luck & have fun with your Desire
Sent from my HTC Desire using XDA App
hello
Having tried different SD card. (class 4 to 6 - 10) for the data2sd or D2EXT, I still recommend a class 10.
but a little attention as stated above, there are many bad card cheap on Ebay. Prefer to buy a card at a site known or a shop.

After a lot of heartache in actually getting the original Desire I bought (original sale is still being disputed in paypal), I ended up buying a 2nd one that had a 4GB Class 4 included with it. Win!
I got an unbranded one, so so far I haven't run out of room (its day 2, give me a week. haha), but its good to know its at least one less thing to worry about if I do go ahead with the ROM
I understand where your coming from about Ebay with the dodgey chinese imports but take a look under the 16GB card on the accessories forum. I cant post a link because im still classed as a Noob lol
A comment the accessories forum on this SD was........
"I used h2test 1.4 with a micro sd adapter to test the speed with the test reading and writing 1GB of data
The test yielded results of 15.5 MB/s write and 16.8 MB/s read."
Ive ordered mine because the 720p is laggy when recording and i was a class 10 for best performance. and for £18 you cant go wrong for a 16GB class 10 Micro SD! Seriously i know where you coming from with Ebay but this is 100% genuine. Good cards and shipped from the UK!!!

Wow, I thought Data2SD only worked with Sense ROMs (and not even all Sense ROMs). Oxygen 2.0 is AOSP right?
I have been running a 16gb class 10 cheap sd card from lowpricememory for a few weeks with data2sd (Starburst and cool Z), the card was tested with write speeds of around 15MB/s and worked ok for a couple of weeks.
However I then started to get errors, with the card mounting as read only and also the odd crash.
I have since swapped to a Sandisk 8GB mobile ultra class 4 card, although the sequential write speed of the Sandisk is only about 6MB/s, the random write speed of small blocks of data is way higher than my original class 10 card.
The Sandisk card makes the phone seem faster, also the quadrant score has improved from 1600 to 2000.
I have formatted and tested the card from lowpricememory for errors since I removed it from my phone, none were detected, so I think that the card is fine, just not suited to running in a phone with data2sd.
It does seem to be that its not all about card class, you need to look into how fast a card can random write smaller blocks of data.
Tests of both cards are below.

I've been looking at this... (Class 4)
http://www.scorptec.com.au/computer/40130-arsdmcl4-32gb
I have no idea who A-RAM are... but its being sold at a real computer store not ebay so its gotta be legit?
Or I could get this... (Class 10)
http://www.scorptec.com.au/computer/40129-arsdmcl10-16gb
But I think I rather the space.
Another quick question, how do I rate my current (8GB) SD card and find out what class it is?
Er, a bump...?
Personally never heard of A-ram but that doesn't mean it's necessarily inferior, why not ask the retailer to provide some benchmark figures for you?. Personally I'd buy the fastest, not biggest card you can afford so would go for the class 10 16gb one.
Try sd tools from the market to bench your current card.
I used to work at PCCaseGear, whho also sold A-Ram, never heard of it before, but the 16Gb Micro SDHC i got performs as fast in a disk test as the nokia 8Gb that came in my N8 before i jumped ship to android. hasn't died yet...
I've used A-Ram before...
Never had a problem with it.
With memory cards I find myself a bit suspicious (bought one a wierd branded mem card for my PSPS and it busted with all my saves...)
Personally I would go for Kingston, Sandisk etc... They also have almost always a 5-year-warranty. I actually just ordered a 32gb Kingston Class 4 couple of days ago.
With phones I would go for size rather than speed. I would get class 10 for a good full hd vidcam or system camera, but not for a phone.
size and speed help, my 32 Gb has a pretty slow write time, which kinda sucks when copying new roms or tunes over. almost considering going back to the smaller but faster a-ram 16gb, solely for write speed.
Ive been using one I picked up from a shop in Aus, a year old now and still runs but some files do go missing... going to buy sandisk from now on.

Dude, a Sandisk Mobile Ultra would pi$$ all over that class 10 card.
WAY too may perople assume that coz, say for example, a Samsung, Patriot, PNY, or whatever make it is...they assume because it is a 'class 10' card.....that it's better and faster......WRONG!!
I have looked into this in GREAT detail......and Bring a Class 10 Samsung, PNY, Kingston (or whatever) to the table......and a Sandisk Mobile Ultra CLASS 4.....yes, CLASS 4, will pi$$ al over the other makes of class 6, 8 and 10!!
I was out looking for a new card and size was not the issue as I hardly ever go over 2-3gb of storage.....so I could of had a PNY Class 10 card for around £20.00.......but instead I went for the SANDISK MOBILE ULTRA CLASS 4 ! !
I've got a couple of old class 4 cards here (NON-Sandisk) and also benchmarked it against my mate's Samsung class 10....
....My little class 4 sandisk mobile ultra BLEW them all away.
please please please don't get any old make, just coz it says "class 10".
Sandisk = the best. FACT!
Here's a Benchmark test result from a very reliable source.
Check this out, very good read:
http://www.tomshardware.com/reviews/microsdhc-memory-card-performance,3011-7.html
"The US-based manufacturer SanDisk is, according to its press releases, the largest manufacturer of flash-based products in the world. Befitting this position, SanDisk offers a complete portfolio of memory cards. The company presents the microSDHC cards on its site’s Mobile Memory section, aiming them at owners of smartphones.
The Mobile Ultra microSDHC card is intended for transferring files between a mobile phone and a PC, which is why it comes with a USB card reader. We tested both the 8 GB SanDisk microSDHC card and the 16 GB SanDisk Mobile Ultra microSDHC. According to the manufacturer, both are Class 4 products.
Class 4 is a real understatement for the Mobile Ultra microSDHC model. Defying its designation, our test sample ran rings around many of the Class 10 cards and exhibited good to excellent read and write performance in all benchmarks. Clocking in at 22.8 MB/s, it even took the lead in our sequential read test. However, it is not quite as fast in the sequential write benchmark, achieving 15.8 MB/s. The card also demonstrates very strong random read and write performance, again winning first place in these categories.
The 8 GB SanDisk microSDHC cannot quite live up to the results demonstrated by its fast Mobile Ultra brother. It really is a Class 4 card, clocking in at 11.6 MB/s sequential reads and 6.1 MB/s sequential writes. Compared to other Class 4 cards, it is fairly slow. Interestingly, the Class 4 Silicon Power microSDHC memory card exhibits precisely the same speed in all benchmarks.
Best part is.....got it at Argos.co.uk for £9.99.
Comes with card reader and software!!
Matt
thanks for the info about this tolls, is a very interesting app
thanks again
I have used the 8GB and the 16GB version and I must say I am impressed. Write speeds are as they stated in the specs 14-17 MB/s depending on the type of file you are transferring. These are impressive numbers for a Class 10 even. Most makers just make sure it hits 10 MB/s and that is it.

I already bought the 16gb version of this card and i must say, it is really fast. i copied the files from my "old" card to the adata with around 16 mb/s. sd tools says the old card can write 5 mb/s, the new one writes 12mb/s, its absolutely amazing
So tempting, looking at reviews on Newegg and then theres this: http://www.ebay.com/itm/Micro-SD-SD...533036?pt=PDA_Accessories&hash=item3a669aef6c
with proof image test.
I am going to buy myself a 64GB micro sd card. I guess I will go with sandisk. But as there are certain sd types there come certain speeds. Such as UHS-ll, UHS-I ,and microSDXC. Now I want to make sure that my phone (SM-G3858) Galaxy Beam 2 is able to do r/w at certain speed levels. But how can I determine that? How can I check if the sd card slot takes UHS-I? I can do a micro sd card speed check when I already bought the sd card (with some apps). But is there any way to check the speed compability BEFORE you even buy the sd card?
I did 3 speeds test on my kingston 18GB MicroSDHC/SDHC Class 10 and the sd benchmark tests were ranging from (max): Read 401,31MB/s Write 10,45MB/s (400 seemed a lot to me, but thats what it said) So that would mean my phone supports at least UHS-l?
I was thinking to buy either the Sandisk Extreme at 45r/45w, the Sandisk Ultra Plus at 40r/lower write or the Sandisk Ultra at 30r/lower write. Or should I go with another brand? Any help is appreciated
thanks
:good:
EDIT: After searching for several hours to find the best 64GB micro sd card I decided to go for the Samsung Evo 64GB. It has full 5 star reviews on amazon and the price was way better than the Sandisk extreme plus. (I paid 37 euros including shipping) This is the best review I found:
"This is a very fast card, particularly suited to not only transferring files quickly but also running as a phone or tablet card for applications as well.
In phones and tablets one of the most important things is not just the transfer speed but also the IOPs that the card can deliver. Many class 10 cards have great transfer speeds but terrible and I mean terrible IOPs, often a 5 year old card easily out performs them in IOPs.
This card delivers in both areas, fast class 10 transfer speeds 23mb read, 15mb write but also 482 write IOPs and 1668 read IOPs.
That's IOP speeds that are slower than an SSD but way faster than a hard disk. Bare in mind that some class 10 cards give 4 write IOPs and you can see why I'm impressed. The only card I have seen outperform it in IOPs it the SanDisk Extreme Pro and they are seriously expensive and not available in 64gb. Testing against the third SanDisk I have, a 32gb ultra, is almost funny as the ultra only gives 15 write IOPs under the same conditions, making this card 30 times faster.
What does this mean for normal use, well it translates into an excellent general purpose card, that even if it doesn't have the official fastest transfer speeds will actually perform much better in the real world. Which is why its getting such rave reviews on here for speed (so long as you get a genuine one!)
This was tested in my Dell Venue 8 tablet using the built in card reader. For the techies (if you've got this far then I assume you are)I am actually using it to run Server 2012 virtual machines in VMWare workstation and the performance is surprisingly good, I would even call it snappy!

So anyways..At one point I´ll wait until the price of the Sandisk 128 GB Ultra plus card drops, then check for benchmarks and try out that one. Enjoy the info, im off
Sandisk is having quality issues with 64Gb cards, with many consumers reporting dead cards in a few months.
The Samsung you have choosen is awesome, along with transcend which are rock solid.
