Hello people, I'm about to buy a secondary disk for my computer. I will buy a Western Digital 250Gb SATA2 drive, but they come in two "flavors": with a buffer size of 8Mb and with 16Mb. The difference between them is U$S 13, not much really, but if I can avoid spending them, the better . So I wonder if there's a real performance difference between both models, considering that my PC is not a server and generally the highest activity on the hard drive is when I defragment it. Our mutual friend Google didn't answer this for me, so I need your help and experience on this Thanks in advance!
