I am choosing a hard drive for my gaming rig that I am going to be building soon and am trying to figure out ways to lower my price some so I can save some of my hard earned cash.

The question I have is what is the real difference in a Hard Drive with a 8MB Cache and one with a 16MB Cache? These are both Western Digital 250GB Hard Drives.

WD 8MB Item: http://www.newegg.com/Product/Prod [...] 6822136113

WD 16MB Item: http://www.newegg.com/Product/Prod [...] 6822136161

Any information on these would be great!

32mb's. This is the best drive on the market today for the money

Don't worry about it. What happens is when a processor needs a memory address it checks L1/2/3 cache -> Ram -> then goes to the HDisk if it hasn't been found. With ram sizes being so massive these days a few mb's of cache on the hdisk doesn't seem like it'd increase performance measurably.

As dustpuppy said, doesn't really matter because you won't feel the difference nor if you timed it (with a stopwatch) between the two when the HDD is being used as an OS+app drive.

Go for best $/GB which for today is 500-1TB and most of those comes with 32MB cache anyway.
