Hi,
Had my SGSII for a few weeks now and I've filled my internal SD memory. Was hoping you guys could help me.
I'm in need of a 32gb class 10 micro SD card for all my HD content. Do any of you flash-a-holic's know of anywhere I can purchase one from? I'm sure I'm not the only one wanting upgrade the memory!!!
Cheers

I have such one from Amazon. It' s from a company I never heard of but works in my SGS II since I unpacked it perfectly and stable. Has lifelong guarantee.

Video rec to sd is nice and smooth and fast, divx videos stored on this class 10 msd play perfect.

Just search in Amazon.....

I personally use Lexar High Speed MicroSDHC 32 GB Class 10 and it works well for me thus far (with full hd content as well)... it also comes with a usb card reader but it's kinda pricey (cost me $95)

I'm a believer in you only get what you pay for so lexar sounds good. In uk Sterling pounds its about £ 60-70. Did you buy it online?

Don't think a class 10 is as fast as you think it should be, I have a samsung 8gb class 6 that will probably out perform most class 10 cards. Why pay the extra

I have a Sandisk 32gb class 4. It stores 5 MB/s. I have a somewhat unknown 16gb class 6 and it is 15-16 MB/s! So buying cards can be very difficult and rather surprising.

This thread is confusing me all the more. So basically its pot luck! From one SD card to the next speeds can be completely different even same class, same brand ! I guess similar to processors!

I have a Kingston Class 10, 16gb but I could not get this app to test it in the Galaxy S2. It seems that you can only speed test the internal 16gb memory. Thats why you get the High speeds...

I have a class 2 or 3 from Sony Erricsson phone and it's faster than yours in reading.

I just checked the app, if you do not mount the sd card it tests /mnt/sdcard (the internal memory) but if you do mount the sd card it does test /mnt/sdcard/external_sd. For me the app works.

I think testing on a pc with a card reader is the only way to get comparable results. I don't trust the phones doing a proper job on this. My numbers above are done using H2testw 1.4.

I got it from Amazon...

Btw using SD Tools (the app people in previous posts used to test speeds) I get 10.8 MB/s writing and 21.7 MB/s reading.. so it's pretty good..

    My recommendation after playing with all sorts of microsd cards and speeds is to get a sandisk 32gb card ( the new sandisk cards do not show a class speed , except for their ultra and extreme cards - This is their new policy )

    Why this recommendation

    - Randrom read write is the most important for speed during normal phone performance and i have seen sandisk cards have it the highest .
    HERE IS A POST FROM SOMEONE IN XDA. Forgot the source
    Class 2 and 4 cards have better random access speed and random read/write than class 6 or 10 cards in general. To get higher sequential write speeds, manufacturers sacrifice the random access speeds. That's just how it is.
    The best all around card I've ever found is Sandisk class 4.
    My 32gb Sandisk class 4 outperforms any other class 10 or 2 32gb card I've tested in the random access and random read/write speeds. That's what's most important when using with WP7 or Android when using it for apps or OS files that need to be accessed quickly. Class 6 and 10 cards are setup to initialize the area of the card that is about to be used to make the sequential write/read quicker, but it takes extra time in the beginning to do the initialization. If your using the card where you need to access small bits of info from various parts of card quickly, you will do best with class 2 or 4.
    Most people seem to assume that the higher the class, the better the card is for everything, but that's not how it is. Different purposes need different kinds of speed... cards with higher sequential speeds have lower random speeds.

    ( quoted from one of the users in xda )

    - Lexar class 10 ( I paid 94 $ for this :-( ) has terrible random speeds. The worst infact. Some of the other class 10 cards like kingston, patriot, topram have higher random speeds. However failure rate of some of these cards ( except kingston is high)

    - Sandisk 32gb is relatively cheaper and very reliable.

    - However if you are interested in regular copying of large files , like for eg : daily trnasfer of lots of music and movie files it might be better to get a class 10 card.

    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
