Hey everyone! I have been wondering what the difference between the Western Digital Caviar Blue 500 GB SATA III 7200 RPM 16 MB Cache and the Western Digital WD1002FAEX Caviar Black 1 TB SATA III 7200 RPM 64 MB Cache hard drives were. Is there a noticeable difference between a 7200 rpm hard drive with 16mb cache and a 7200 rpm hard drive with 64mb cache? If you're wondering what programs I would be running these on I will mainly be gaming and copying files.
