a 7200 rm hd is considered a gaming quality hd. look at the cache the drive, 16,32,64 are common sizes, the bigger the better the drives will perform, I have a 7200rpm, WD blue with 64mb of cache, I can say it's a decent drive but is by no means superfast, takes about 45 sec to fully load everything stock...it scores 5.9 on WEI, everything else scores 7.4+. it is the slowest thing on my computer.
