well hence since there are only hdd's on the market for large storage, instead of complaining, help with the first question, and YES i do see an increase of of performance, and I am a poster boy for raid, I have 8 Tb in raid 5 in my server, i have 1 Tb in raid 0 and 75 Gb in raid 0 in my main machine. If you feel so inclined, go work for WD, Maxtor, Seagate and come up with a better solution for large storage. Do I look like i have dimm chips coming out of my eyes, thought not, so as long as i dont see stuff slowing down im good!
