In the previous post, Part 1, I took down the server early due to unforeseen circumstances. Today, I spent the whole afternoon bench-marking the drives in raid 0 configurations. I have settled with 2x 10K drives over a 15K drive because the 10k has a max power consumption of 8.6watts x 2 whereas a 15k draws 19watts max. Lesser power means lesser heat and also lesser vibration noise.
The test is performed on an intel system and PERC 5/i raid card.
