Samsung Plus 16GB microSDHC

I just got this...seq writes are very good...very disappointed from the random writes..i only got Samsung based on the 32GB card results on previous pages...

Note : the card is black colored although that specs show silver color...weird ?

I tried again with the card in my Galaxy SII, connected via USB cable. The results are better (last pic), probably the adapters trashed my results....I'll buy a better adapter and try again for max numbers...

I have also ordered the 32GB one in previous post...will provide tests when i receive...

Ebay

Ebay is the perfect place to get it from.. I got a water-proof, dust proof, force-proof class 10 32 gb card.. its perfect.. and i also tried putting it in water and then wiped it and used.. perfect with no loss in write speed.. write speed is also very high with a normal micro sd card adapter.. following is the link to it.. please check if the seller is a powerseller and then buy it.. cuz they can easily.. and dont buy from anyother than uk and us sellers.. becuase there is a special protection for the buyer against these sellers...

So its very gud.. awesome.. card. its samsung company.. check it out i bought it from korean. its not racism its just avoid others if u find us and uk i dint find so i bought it form korea.. but korean products have no such buyer protection..

But whatever comes may,, U HAVE TO CHECK FOR POWERSELLER:) or else 90% chances u will be cheated.. i have gotten cheated 100 timess.

Thanks,

Sandisk class 4 32GB has better random read/writes than class 10's

Android phones rely on random read/write NOT sequential.

[Galaxy S II Accessories] Theflying:
I got the Samsung 32GB class 10. Works like a charm and pretty fast. Don't have any speedtest results yet.

And if I am correct the class is only a indication of how fast it can go in it's lowest speed. That would mean that a Class 4 can be easily faster than a Class 6 because of the usage of higher quality of material or configuration or what so ever. Correct me if i am wrong.
[Galaxy S II Accessories] Krakataus:
Correct. It is on the interest of the manufacturer to give the highest possible class to his memories.

Have a kingston class 10 and a sandisk class 4, both 32 gb, kingston twice as expensive. (I have to say I bought it two months earlier as well)

Sandisk is the card that I always have(had) in my device! Random writes are highly underestimated. Thing is.. My phone got ripped, with my card in it. Ordered a new sgs2 two days ago and a new sandisk card. Will be getting an official one for 43 euro's from a big e-seller in holland.

Bottom-line, If you want your card purely for transfer speed, (copying movie, music, and other files.) Get a class 10. If you dont mind waiting two minuts more, but getting a better in phone performance. I would recommend getting a sandisk class 4. Their speeds are comparable with other cards class 6 and they are the best in random writes. Im sure people can confirm my opinion. It's also better for your wallet!

Edit: Since people will probably want to know. There was no difference whatsoever between the class 10 and the class 4 cards in playing from and recording-to Sd with both full hd and 720p.
[Galaxy S II Accessories] cheekystew:
Thanks for the reply. In-depth and just the information I needed. So a class 4 will cope with all my mobile needs just fine.

I'm a bit disappointed so far with a Samsung class 10 32gb sd card. Read is fine (22,87), write is half of what I see with others (4,085).
[Galaxy S II Accessories] CroWarrior:
Hi,

I plan on buying new 32GB SD card, and here in shops near me (Zagreb, Croatia) the prices are really similar (the difference is below 0.5$), so I am not sure what to buy, concerning the post stating that class 10 can be worse than class 4.

There are a lot of cards, and I focused mostly on Transcend/Kingston class 4/10 32GB cards. Which would be the best quality card?

I would use it in my smartphone, mostly for storing music/videos, captured photos and videos and a few applications moved to sd.

I have Zenfone 5, but I believe it does not differ from GS II too much. :)

Thank you in advance. :)

[Galaxy S II Accessories] stoatwblr:
It's a few years on and class10 is old hat now. If you want to go faster, you need UHS-I

UHS-I 1 = class 10 (the numbers with Class 10 represent write/read speed)

UHS-I 2 = double that

UHS-I 3 = faster still

As asn example: http://www.integralmemory.com/product/ultimapro-x-microsdhc-90mb-read-45mb-write-class-10-uhs-i-u3

These are on sale for around $30 and are rated at 90Mb read/45Mb write.

i would like to get a bigger faster sd card, dose it get any faster than class 10?
[Galaxy S II Accessories] -Tj-:
Good thing I read this thread 'cause I'm looking to buy a 32GB card today. My usage is going to be mainly storage of movie files, music, photos, and other types of data that's just stored, and I've always been annoyed by how long it takes to transfer large files and large amounts of files to cards. I don't think I'll be running anything off it, but I'm new to Android. On WinMo 6.5 there was the option to install to SD, but that was really necessary because there was so little storage on the phone to begin with.

That said, should I go with a Class 10? Looking at the Lexar one ($83 on Amazon right now)...
[Galaxy S II Accessories] Mew178:
So one of the shop here in Croatia got the Transcend 32GB microSDHC CARD Class 4 (TS32GUSDC4) for 78$ just a week ago.

Compared to the Sandisk one that costs like 130$ is it worth it?

How does the Transcendent one fare? I'd probably mostly use it for Music and Video storage and Photos and Vidoes shot by the phone camera.

I guess I do mind the slow transfer times but Class 10's are so goddamn expensive.
[Galaxy S II Accessories] stesteste:
make shore ur sandisk isnt fake

DIFFERENCE BETWEEN GENUINE AND FAKE Sandisk 32 GB micro SD:

1. Package: The genuine pack is sealed and cannot be split open. The fake is just pasted at the edges and my fake item was all loose inside. Again, as far as I am aware, Sandisk does not provide any SD adaptors (Kingston does) but nearly all eBay items have a `free adaptor' inside the same pack.*

2. Check the barcode: If you have a iPhone with a barcode facility (like a Amazon/eBay app), check the barcode on the reverse of the pack. My fake eBay item barcode read 4GB instead of 32 GB.*

3. Check the external details: Sandisk, currently only makes Class 2 for its 32 GB micro SD cards and I confirmed this from Sandisk helpline in the US. eBay sellers are selling fakes as `Class 6 - 10' !!!*

4. Check the inner details: Once you open the pack, check the card. All genuine cards should have a serial number and a manufacturing country's identity. Fake ones neither have any such details and the external details are painted in a hazy style (see photo).*

5. The Catch: When you put in a fake micro SD card for the first time, you will be surprised to find that it reads the correct GB in the properties. Apparently the goons have made a software which enables the card's storage properties to give out a false capacity. One way to check this is to copy at least 60% date of the `claimed' capacity and check the card in 2-3 days time. There will be lost data in all fake ones.*

6. Finally the functionality: Download a simple programme called H2testw (ver 1.4) from the internet. It is German software and the most recommended to test all your portable media including micro SD cards. My fake one showed only 3.96 GB capacity instead of 32GB as claimed.*

7. Where to buy: spend the extra bit of money and buy from genuine big dealers. Amazon is always one of my foremost places but keep away from Amazon Marketplace since the same firms also sell in eBay i.e they are mostly shady and refunds will need a lot of wrangling. Of course, you might occasionally be lucky (as yours truly had hoped!), but one would probably need to be as dumb as me to follow my steps (till I became wiser!.*

Hope these steps help the next prospective buyer

thank me

Instead of posting the SD Tools results which is just sequential read and write, could you guys use Crystaldiskmark instead to test the random read and write? The random results are relevant to apps/games/photo performance as well as when playing back fragmented video files.

[Galaxy S II Accessories] Stitch!:
I agree with you, I am getting an almost double random write with my 32gb sandisk class 4 card. Which costs almost half. The sole reason I see for buying a class 10 of most brands is because you want your movies/music collection to be on your on your card 2 minuts faster.. Which is not a good reason to spend that much extra on a card.. Really people should know that random read and writes are the only thing that indicate the "real" performance on smartphones.
[Galaxy S II Accessories] Aero:
Where did you picked up a sandisk 32gb microsd class 4?
[Galaxy S II Accessories] Stitch!:
I have an apartment in Holland so I ordered it on digitals online.nl for 42 euros. (cheapest I found in france was 60 euros...)

Depending on where you live I would check some of the big e-sellers. Watch out for offers under 40 euros and ebay. There are a lot of people selling fake sandisk cards out there.
[Galaxy S II Accessories] Aero:
I know what you mean about ebay, that's why I am trying to avoid it as much as possible. I can only find the class 2 sandisk 32gb on the regular online store that I frequent.

Here is the results from my Lexar 32GB MicroSD...

If what you're saying about random speeds is correct I am beginning to wish I had read this thread first and gone with a Sandisk! However, without the benefit of hindsight, I still think that I got a pretty good deal on a quality 32GB SD Card (under £50!).

I do have one question though, unlike the 'SD Tools' app, and the Android Storage info in Settings (which both show around 29GB Free on my SD Card), other apps such as 'Storage Info', 'SD Card Storage Widget' or 'eFile' show a lower number under SD Card...

'Storage Info' app shows:- Internal- Free: 1.56GB, Total: 1.97GB, SD Card - Free: 9.47GB, Total: 11.50GB. The eFile app, and SD Card Storage Widget shows the same numbers under SD Card. This really freaked me out at first and made me question if I had bought a dodgy fake SD Card! I now realise these amounts credited as being the SD Card storage are the same as what is shown under 'USB storage' in the Android Storage settings!

Can anybody explain why these things are under different names? Is it something to do with Samsungs file system?
[Galaxy S II Accessories] nybreath:
Im about to buy a new microSD card.

I just wanted to know their performance first.

But all i can see here is just sequential read and write tests, their are really nowhere close to real life usage.

Could you do some random read/write test speeds please?
[Galaxy S II Accessories] cheekystew:
Please read the thread dude!
[Galaxy S II Accessories] Sleepycat3:
It is Android. SD card refers to the phone's internal memory allocated to storage if you follow Android's directory naming method. Then the microSD is called the external SD.
[Galaxy S II Accessories] iamthecosmos:
Strange! Thanks for the explanation though! :)
[Galaxy S II Accessories] nybreath:
I read the whole thread and there is only 1 guy that did a random write test, the other just uploaded pics of sequential test.

what should i read?
[Galaxy S II Accessories] reyza:
The random test involves removing the card from the phone, popping it into the adapter, getting the test on your computer and running it. That's more effort than most are willing to put in for the sake of a thread.

Unless I missed it, I didn't see that there was an app that can run the test on the phone
[Galaxy S II Accessories] nybreath:
Didn't know that.

The problem is that all these sequential test aren't really telling anything about how the micro sd will perform with the phone, if not in the rare scenario where you are transfering a big file and you are so lucky to have a sequential free space big enough, that is extremely rare unless the card is empty.

I have read some ppl saying how awesome the performance are looking at those test, and they should understand that those tests are a lot far from the real performance, ppl shouldn't be misslead by those big numbers.
[Galaxy S II Accessories] cheekystew:
Basically San disk 32gb class4 is about the best. Don't over pay for a class 10 that will under perform in you're android handset. Sometimes less is more and in tis case is certainly true!

Glad I created this thread, it saved me money and helped me get the best out of my SGSII.

So basically, the best 32gb microsd card for a smarthphone is sandisk class 4...

so anyone knows where could i get one of these cards, genuine one of course.

Any good reliable online site thats ships internationally?
[Galaxy S II Accessories] nybreath:
Awesome thank you a lot.
[Galaxy S II Accessories] Sleepycat3:
Note that it is the older cards that are fast. Newer cards now have slower random speeds. So a new sandisk class 4 could be slower than an old sandisk class 2 or 4. Manufacturers tend to keep changing the base cards used in the final product.
[Galaxy S II Accessories] nybreath:
Yeah in reality the faster cards are those with more NAND chips, and newer cards tends to have less of those.

Mustang Class 10

Here is result from my Mustang 32 gb class 10, bought from Sweburn.
[Galaxy S II Accessories] :
So how do we find a SD Class 4, older version and what should I expect to pay for one? Is there a born on date located somewhere on the package? Or a type of packing that is unique for that time so we can differentiate between the cards issued today?

I really, really need something soon. I found this in a current photo magazine:
[Galaxy S II Accessories] Stitch!:
Your picture is not an micro sd card, please pay attention to this, otherwise you will spend cash on a useless card.

New packages are red, and sandisk is only selling class 2 right now so if you find a class 4 its an older model. See the new model/package in the image below, and the old model I have. (fast random speeds)

Class cards of the older model are also supposed to be better than the new one, packaging is the same.
