I'm trying to hunt around for a solution to a disk issue I have with my home server. Basically, I started to use it to stream video (going from a virtual host, it now does alot more). I see alot of lag and I am fairly sure it's my motherboard's SATA output. The 2 drives I have storing the video are RAID 0 SATA II drives on SATA 1 ports. I'd like to upgrade these drives to 2TB SATA III drives, but I need a solution.
My motherboard is an Intel D975XBX2
It has a Radeon x1900 (old card), Q6600 (old quad core), 8GB ram, and 5 drives at the moment. I am tryng not to rebuild.
Any suggestions on how to increase the I/O keeping in mind that this is also a storage server, domain controller, virtual server (hyper-v), running W2k8R2?
