Micro Center Class 10 SD cards

I was at Micro Center today and decided to pick up a couple SD cards to use for my Raspberry Pi (when and if I ever manage to get one).  They've always carried house brand/bulk USB flash drives and SD cards for pretty cheap.  I've bought a bunch of the them over the years and, while they work fine, they always seemed pretty slow.  I was thinking I would get a name-brand high speed SD card for the RPi but then I noticed they carry an "Extreme Speed" house model so I decided to check one out.

kevin@minteee ~ $ sudo hdparm -t /dev/sda
Timing buffered disk reads: 88 MB in 3.00 seconds = 29.31 MB/sec
kevin@minteee ~ $ sudo hdparm -t /dev/sdb
Timing buffered disk reads: 46 MB in 3.11 seconds = 14.78 MB/sec

/dev/sda is the internal SSD on my EeePC 701 and /dev/sdb is the 8GB Micro Center card I bought.  It seems to be about half the speed of the SSD on reads which seems like it's pretty good.  I don't really have anything to compare it to at the moment though.
