There's pros and cons to getting Class 10 cards.

From what I read, Class 10 offers the best read/write speeds so this is a positive point.

The problem is, the random access performance of higher class cards is not as good as the lower class cards.

Some users have stated that Class 10 cards in their Android devices have created lag, which is attributable to the lower random access performance.

Personally, I'm using a Class 4 32GB Transcend card and so far I've not experienced any problems. I did use a Class 10 16GB Kingston and it my Play did suffer some lag.

I think the main advantage of higher class cards is performing file transfers between sources, as the higher write/read speeds would indicate.
[Xperia Play Q&A, Help & Troubleshooting] crispyduckling:
yes that is true some people say that there class 10 cards give them lag in games.

i have a class 10 memento card in mine but i havnt had any lag issues

but i do notice that transfering large amounts of data

and loading games times are faster on a class 10
[Xperia Play Q&A, Help & Troubleshooting] J4r3dP:

[Xperia Play Q&A, Help & Troubleshooting] AndroHero:
if a sd card dosent state the class on it, it will most prob be a class 2. i have a class 4 32gb kingston card, but ive used class 2 on all my other devices with no issues :)
[Xperia Play Q&A, Help & Troubleshooting] bigsky2:
If you look on the microSDHC card, it will have a circle with a number in it. That is its class.

If there is no number, it is Class 2.

I bought a class 10 Lexar 32gb microsdhc and i was shocked when i put it in my play. It was lagging in all the gameloft games most noticeably in Sacred Odyssey. I returned that and bought a 23gb Kingston class 4 and i have no problems with that :).

I think its because the card had problems reading lots of small files, i noticed that when i was copying my data over the speed was coming down to 1mb!

[Xperia Play Q&A, Help & Troubleshooting] speedyink:
I just bought a 32gb kingston class 4 for $17 off ebay :D

It's not that bad, and digital zoom (which is the only zoom phone cameras get..'cept for that one japanese one..) is just as effective as zooming into your picture after you've taken it. It's a useless, garbage feature, and everyone who misses it should be ashamed.
[Xperia Play Q&A, Help & Troubleshooting] subcu1ture:
well digital zoom is pretty ****ty anyway, it is pretty much zooming into the full size image live and then cropping it and enlarging it. You get better results taking a full frame image and then zooming and cropping on your pc.

I also have read in other places that the play is capable to 720p.

Sony usually likes to keep thing hidden so when they release an update you stop raging for a while because there are pretty new things that the device has always been capable of.

DIFFERENCE BETWEEN GENUINE AND FAKE Sandisk 32 GB micro SD: (see my self-explanatory photographs for each point)

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

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!.
[Xperia Play Q&A, Help & Troubleshooting] speedyink:
Luckily I purchased through Paypal, and apparently I'm covered for such instances. So all should be fine. Just have to wait now.

Still looking for my 32GB card.

Cheapest I have seen from a reputable seller and brand is just under £50 for a Class 4 card.

Ideally, want a Class 6 (though 4 would be an improvement on the Class 2 that came with my Play).

Also despressing that the 32GB cards seem to be holding their price when at certain times, you can get genuine 16GB cards for around £10.

£50 is just too much for me, waiting for a price crash.:D

[Xperia Play Q&A, Help & Troubleshooting] liaoip:
Hello,

I started off with a Lexar 32GB Class 10 card. Since I didn't have anything to compare it against at the time, I thought the lag and slow boot up time was normal. However, after reading a few threads and researching, I bought a Sandisk 32GB Class 4 (tested) and the system is much quicker. Whether it's the boot or loading icons for programs stored on SD or access times, everything is much quicker. Now I'm stuck with the Lexar that I have to sell on ebay.

So my 2 cents: go with a class 4 32gb (I think according to the tests done here http://xdaforums.com/showthread.php?t=1150369) the Sandisk is the best overall.

I bought sandisk

I bought a few 32g class 10 on ebay, they all failed to store data. but all had higher capacity then the sandisk class 4. the cards off ebay only brand named as "micro hc" formatted with 31.1g available and the Sandisk only allows 29.5g of the 32. the sandisk is the only one that worked without error though, if i put files on the micro hc it wouldnt ever be there after i looked in root explorer on the xplay. the sandisk always had the stuff there and ive had this card now maybe 6 months, used in my droid 2 global.

Id go with sandisk, a little less gb but a lot less frustration, no lag on games, im running everything installed on sd card.
[Xperia Play Q&A, Help & Troubleshooting] Rogue Leader:
Sounds like those Class 10's you got were fakes.

Incidentally I got a Cheapo 32GB card online for my nook and it comes out as 31.99999 GB which I assumed meant it was a fake, but I tested it and while it was not a fast card it tested to the full size. But yes the Sandisk on the other hand is usually around 29.5-29.8 GB, but it is noticeably faster.
