Hey guys, I need a new USB flash drive for my keychain, my current one has crapped out. I want something really tiny. Most of the small ones don't have great reviews, or don't seem rugged enough to be on my keychain. I did find this MicroSD card reader, http://www.amazon.com/ELAGO-Mobile-...?s=electronics&ie=UTF8&qid=1321033485&sr=1-16 I was thinking of getting that and then getting a micro sd My question is whether or not that will be comparable to a regular usb flash drive. I found this table: http://en.wikipedia.org/wiki/Comparison_of_memory_cards But I'm not sure how to read the read write speed. Higher the better right? Are those numbers right for the USB? USB is 1-40 while the MicroSD is 133/133? over 3 times faster? I probably dont' really need speed specific, but I would like to know.
