I just installed my Barracuda V 120 Gb with 8 Mb cache, which replaced my "old" 80 Gb Barracuda IV with 2 Mb cache. Xbench 1.0 gave the old configuration a rating of 50.96 with disc test at 55.61. The new configuration (system carbon copied from the old drive) got an overall rating of 54.48, but more importantly a 82.56 for the disc test. I guess the 8 mb cache is doing its job...;-) I get a feeling that the new drive while reading is a tad bit louder though. Now I'll finally install my Radeon 7500...:-) Regards, Joakim
