I am just about to buy a new Desktop PC, I notice that I can upgrade the hard drive to one with 8mb buffer, what is a butter and is it worth paying a bit extra to have a hard drive with one? Thanks, Tomsdad
"...A good empirical example may be found by comparing Western Digital's Caviar WD2000JB (8 MB) with the WD2000BB (2 MB) (cache). As illustrated by the comparison, the 8-megabyte buffer delivers a single-user, desktop machine a 30+% performance gain. This gain goes a long way to closing the gap between 7200 RPM ATA drives and their 10,000 RPM SCSI/SATA counterparts..."
