16GB class10 kingston vs 32GB class2 Sandisk

Hey, I need some advice on which card to get;
I like having loads of space, but I also want a card capable of recording p720 video and run apps from SD in a decent manner.
So what card should I go for; 16GB class10 kingston or a 32GB class2 Sandisk?
They are about the same price.

I'd say go for the class 10 16Gb.
In my TP2 I have an 8Gb class 6 and read write speeds are wayyyy faster then my class 2 4Gb. A class 10 would be great for taking pics and videos without lag.

True, but do you really need a min transfer speed of 10MB/s to store those pictures and videos? AFAIK, a picture taken using the Desire camera is approximately 1MB...
Just some food for thought.

how about hd recording? whats the transfer speed?

the Class 10 16GB wins hands down, try using class 2 in android 2.2, your phone will slow down so much its annoying when loading large apps from sd

You don't "need" it, but you will notice a HUGE difference in the speed of taking and saving the pictures and videos.

class 10 hands down!

Get 32gb class 2 from SanDisk without question.
I have a SanDisk class 2 16GB microsd card. Here are the benchmarks:
Code:
Sequential Read : 17.914 MB/s
Sequential Write : 9.358 MB/s
Random Read 512KB : 17.922 MB/s
Random Write 512KB : 2.131 MB/s
Writing an image or 720p video is (more or less) sequential, so You can expect to have around 9MB/s which is more than enough. Class 2 means writing speed in worst case scenario is minimum 2 MB/s.

Do you have any tests/benchmarks that would show this? I, personally do not believe this since random read speed = sequential read speed = ~18MB/s.
Class 10 microsd card has about 23MB/s read speed. That is not much different from Class 2.
Besides, how big would an app need to be to notice the difference between 18MB/s and 23MB/s ????

Just found another benchmark of class 10 kingston:
CrystalDiskMark
The benchmark runs the test in Seq read/write, 512k read/write, 4k read/write.
In the 4GB Class 4 test, we can see a Read of 20MB/s and a write a 7.16MB/s. That is pretty good for a Class 4 card. When it comes to smaller blocks of 512K and 4K, the performance dips in the writing to 2.9MB/s and 0.039MB/s. Reading 512K is still at 20MBps.
[...]
With the 16GB Class 10 card, we can see that sequential read is 19.8MB/s which is almost consistent with the 4GB card at 20MB/s. With 4K block, the read is slightly slower at 3.2MB/s. A check on the write, we can see the sequential writing seems to be almost 2 times faster than using a 4GB card. It writes at 12.45MB/s. Writing 512k and 4K blocks are slower though. It proves that Class 10 card can write with a minimum of 10MB/s sequentially.

any chance you could do a benchmark with the speed tester app on the market to see if the speed is the same on the phone?
http://www.appbrain.com/app/br.com.fast4ward.sdcardspeedtester

My phone is currently in the service for warranty repairs. I can check it as soon as I get it back.
If it turns out slower on the phone, that would mean the phone is a performance bottleneck - proving class 10 cards even more pointless on Desire.

Seems the best bang for buck would be the 32gig one then judging by the very little difference in transfer speed!
Think I might look into one myself seen as though the desire has now become the replacement for my ipod video.

that's my thinking behind it, no point getting a fast card if the phone is a bottleneck.
i've only got a slow card so cant confirm one way or the other, except i dont get any slowdown i notice with apps2sd.
on the phone my PNY class 2 16gb card:
3 MB/s write
14 MB/s read
on my laptop (with H2testw1.4) Clicky
3.95 MB/s write
14.8 MB/s read
not much difference for me, i still had apps running on the phone and using the tester via apps2sd - so probably about the same.
EDIT: just tested it again after a rebootiing the phone, 4MB/s write & 15MB/s read so mine is class 4 speed on the phone and my laptop.

How did you get such reading i ran the application on mine and only got write speeds and reading speeds it also seems to always be .0, does it round up or down?
I did three runs and results were around Write 10.0MBs, Read 19.0MBs give and take a MB (results being the highest). I also get ClassUnknown on 2/3 of the tests!. The slowest was 8MB Write and Read 17MB which now i look at it doesnt seem to be that fast.
I did same tests on a 32GB Class 2 Sandisk and the results were the same compared to my class 10!!! cluster sizing is whatever windows 7 defaults them too, cards cleaned, not sure if its worth doing the tests again but with used space on SD?
I tried the same tests on 8GB Kingston / Sandisk 8GB Ultra Class 6, Class 4/2 are Kingston and Sandisk, both produce same results.
Class 6 and Write 7.0MBs, Read 14.0MBs,
Class 4 and Write 7.0MBs, Read 12.0MBs,
Class 2 Write 6.0MBs, Read 12.0MBs
I have not tried to benchmark these SD cards out of the phone onyl using that app but from looking at the app test results there seems to be so little gain for such big spend.

Reviving an old thread.. but i have two questions:
1- Are 16gb class10 cards even compatible with HTC Desire? There is no clear indication on this anywhere.. atleast to my info
2- Any class10 user here who can vouch for the difference in speed? Is spending 100$ really worth switching from a Class4 card??
Thanx in advance

I had a class six card vs a class two that was larger with my HD two. And when running an app, such as Igo navigation which all the files were on the SD card I could tell that the bootup was faster. If you are just using a card for storage and not using it to run important things then go with the cheaper one.

Class 10, this is the first time I heard this standard. How fast it can run ?
Sent from my HTC Desire using XDA App

With an aligned partition you can get read/write speeds of about 10 MB/s instead of 2-3 MB/s. That's what I got on the PC. Dunno how to easily see this on the phone
Sent from my HTC Desire using XDA App

Ok, enough about read/write speeds!
There's not only advantages on speed with higher classes, there's also better performance in read/write cycles. Meaning longer life for our little buggers the higher you go in class.
You know that these things have limited write cycles right?
The choice is yours!
RayanMX

if you are just planning on using app2sd, it doesn't really matter which card you use, but if you're planning on going one step up like data2sd/data2ext then a 32GB class2 sandisk is much much much much much much much much much much much much much BETTER!
the reason why it's better is because what determines how much of an improvement data2sd/data2ext is over stock setup is how fast it can read/write small files (i.e. how fast it can write sqlite)
it's well documented that a class2 32GB sandisk (i'm only talking about that particular card, card of different size/class or manufacturer is a completely different beast) has a 4k random write speed of 2.5MB/s wheres kingston crap is about 0.04MB/s, sandisk32gbclass2 is 60 times faster than kingston crap
i foolishly listen to ppl on this forum about getting a class 10 microsd for improved performance so i bought myself a class10 4GB patriot microsd, it is a piece of sh!t! i benchmarked it with crystaldiskmark and sure enough squential read/write were 18/12MB/s well within specification. However the 4k random write was only 0.03MB/s
today after doing some research i forked out $20 to buy a class4 4GB sandisk which has 4k random write speed of 1.15MB/s, my phone has never been faster

[Q] Class of SD cards.

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.

microSDHC Measured Speeds

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.

[Q] Recommended Micro SD for P500

Hi guys! my 2gb samsung micro sd just crashed. Can you guys recommend any micro sd I should buy for my P500? please state the brand and size (and class if possible).

I'm also searching for one, I think a 8GB class 6 would suffice. Any suggestions for brands and prices? I only know transcend.

You can try play-asia.com
I have ordered one a-data 8 GB class 6 recently from there

I think m friend bought a Final Fantasy XIII PS3 korean release in there. its reliable. I just dont know how long it will take for the package to come(also depends on where u are tho).
I have a follow up question. Will having a class 10 sd have a great impact on the performance of the phone? or is it just too much for our phone to utilize that class 10 speed?

Don't buy from ebay, there are a lot of fake sellers who sell fake cards with fake storage, very low speeds and stuff.

It would depend on what you are going to use the card for. Will you be storing your programs on the memory card? Dalvik cache?

Woaw! It's been a few... err.. since i last viewed this thread. Thanks for the response!
Will be checking the 8GB class 6 you guys mentioned along with the class 10 franco gave a link to (but i think it's quite expensive).
And, yes i will be zipaligning my apps, store them in ext, and transfer cache into it too.

i wont be able to buy items from ebay (because of where i live), I will have to find the item locally. I saw that item too (posted by franco), and i really want to get my hands on one of those. XD Hope I can find those here in our place. XD Thanks for the response, everyone.

If your attempting to take videos with your Optimus, then the faster class cards will probably make a difference. Copying files to your microsd card will be faster using a higher class. Accessing your photo gallery will be faster. In other words, it will help when you read or write non-random large files.
I am a lot less sure that a Class 8 or class 10 will be of benefit if you want to speed up your use of programs/data and Davalik cache moved over to your memory card. The big question is whether writing small files is critical to the overall speed of your Optimus. If writing small files is critical the speed of sequential reads or writes of large files is far less important which is what the class rating is telling you.
I would rather buy from the little guy/manufacturer that has a brilliant product. However, I recently bought 2 Sandisk class 4 cards for android devices. I tested them with Crystal Disk Mark 3.01 (64bit version).

I learned a couple of things. I ordered 2 Sandisk that were supposidly the same from the same dealer one week apart. They performed differently. The relative performance of the Sandisk cards writing 4k files compared to others was startling. I had seen such results reported before but it had more impact on me when I saw it myself. Since I will be using A2sd, I am happy with my Sandisk cards.
PS I also verified that the Sandisk cards were really the size proclaimed by using H2testw v1.4
PPS I have heard that older class 2 Sandisk are often faster. I also heard that Sandisk is in the process of discontinuing the class rating of their microsdhc cards.

@explore3: that's quite a lot to ponder on... I will be researching on the cards that I will be finding here in our place... I'm aiming for a class 6 8gb and that a-data class10 8gb if i find it here. I know class 10 cards are (maybe) too much for our phones but i like taking a lot of pictures since i learned how to take good macro shots with our phone. Taking videos would not that be great because our phones are capped to quite mediocre quality video recording.
I think i saw some sandisk cards in here too. I will take a look at them along with the cards im looking for. Thanks for the input.

i think depends on your use... 4gb is enough if u have partition + lot of apps, 8gb enough if u have partition + lot of apps + lot of music and 16gb if u have partition + apps + music + hd games + videos
of course class +4

Well explained.That's why I opted for 8gb =]

Thinking of getting a 32 GB class 4 card from a store is US via ebay. Is anyone one using a 32 GB card? Would I face any problems with it? Dont plan to use any app2sd patch. What are the things I need to take care while buying one?

No patch? You mean to say you're gonna fill that card only with multimedia files to be viewed on a O1? kinda weird :/ But to me class 4 is too weak for a 32gb card.

[Q] How to check micro sd card speed capability on a phone beforehand

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!
Full Crystalmark disk scores below.
Sequential read 23.66mbs write 16.03 mbps
512kb random read 23.25mbs write 15.67 mbps

4k random qd32 6.65mbs write 1.92 mbps
Parameters 5 iterations 1000mb sample size.
Tested on the 64gb Samsung Evo microsdhc."
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.
