In addition to offering a lot of storage for only a little bit of cash, the SanDisk name has a much better reputation than Patriot, which a few G&E readers pointed out is known for a high failure rate. In fact, SanDisk's quality is so good that this class 4 card has been observed to be twice as fast as cheaper class 10 cards in some benchmark tests.
This card has received overwhelmingly positive reviews on Amazon, comes with a micro SD card adapter, and will be shipped for free to your house in two days if you're already a Prime member. And with this deal arriving in the weeks before preorders start for the HTC EVO 4G LTE, it couldn't have come at a better time.
[Amazon]Update: A SanDisk 32GB micro SD card, along with an Everything But Stromboli card reader, is also available on Amazon right now for only $22.75. (Thanks, Peter!)
