I've read quite a lot about the difference between 2mb and 8mb cache drives being just a lot of hype. When I've looked for speed benchmarks, it seems that I'm always finding the 2mb cache Barracuda V, but nothing on the 8mb version or any head to head comparison. Does anybody know from either personal experience, or otherwise, which would be the better way to go? I recall seeing something where some 8mb drives had actually been clocked slower than their 2mb counterparts. And how are Serial ATA vs EIDE drives?
