32mb vs 64mb cache

[Kylothian]

Hey.

Sorry this just bugged me.
Im looking to get a new drive, and ive been poking around trying to find the differnce between the 32mb and 64mb Cache drives. Is there a difference in speeds ect?
Im looking at the WD Caviar Black im sticking to 7200rpm 64mb cache but is it really worth that extra few bucks.
Then I also saw this HDD:
Western Digital caviar Green 2Tb, Sata3G , with intellipower ( 5400-7200rpm for powersaveing ) , 64mb cache for less than the Caviar Black
now i dont know if its running at 5400 or 7200.

Sorry if this is a crappy question, but it just bugged me

Thanks in advance

stick to black.. green is nice and newer... but keep ur money doesnt make such a drastic differecne... saving money on hd is good and waste more on gpu/psu/cpu/case instead

The more cache the better, and a drive with 64mb cache will run faster than a drive with 32mb of cache.
