I have a retired server that I use for video encoding. It has dual quad core Xeons, 16 gigs of ram, and an Radeon R7 250. It's not spectacular, but mainly the hard drive is what's slowing it down. I want to set up RAID 0 with 2 10k hard drives, but the raid controller is connected via PCI-X. Would it be a waste to replace the hard drives with faster ones with this type of RAID controller?
