Or you can get the same 32GB card $20 cheaper on Amazon: http://www.amazon.com/SanDisk-32GB-m...5217690&sr=8-2

I saw that one at Amazon and I stayed away because I couldn't find any information on the Class? I was under the impression that a Class 6 was optimal but I think the current 4GB card I'm using is only a Class 4???

I ended up ordering this one - 16GB

I'm not sure how big we really need. I realized this morning that I've spent hours now fiddling around with this machine that is probably 92% of the time an Angry Birds game player.

Class is mostly irrelevant unless you're planning to run an OS such as CM7 from the card, in which case Sandisk unclassed/c2/c4 8GB and 16GB cards have been reported to outperform pretty much any others, and to outperform higher class cards by a wide margin. I'm running the latest stable CM7 overclocked to 1.3Ghz from an unclassed Sandisk 16GB right now, and it blows away the stock OS.

Any card higher than class 4 is probably going to have terrible small-block random writes, which *appears* to be the benchmark most predictive of performance as an Adroid boot drive. Those cards have been optimized for moving large blocks of data, which can result in small-block writes a couple orders of magnitude slower than an unclassed card, which hasn't been optimized for anything.

If you're just using the card for storage, a higher class card will let you copy large blocks of data to and from the card several times faster (like moving video files from your PC), but won't affect performance.

Keep in mind that if you are running CM7 from an SD card, you probably don't want a 'high-speed' class 10 card. These are optimised for large linear read/writes, and tend to have very poor performance for small random read/writes, which is what seems to affect CM7 response and stability the most.

Edit: Or... what they said.
