I currently have a p3 600 w/256MB WIN XP Pro and a WD 100MB drive. At times my PC is slowwwwww. I know it is my I/O subsytem. I am planning on upgradeing the PC to either p3 1.26 or a p4. I may switch to Windows 2000 workstation too. I want to go with a RAID 5 solution on my PC. It will serve my performace need as well as a backup need that I am seriously lacking. I also want to have ~250GB of storage. I am currently looking at SCSI and Fibre Channel. I don't think I want IDE. Fibre Channel drives are cheap but the equipment is expensive. I see adapters that will allow you to juri-rig and avoid some cost but I don't know if I want to go that route yet SCSI drives are more expensive but are always falling. Equipment is fairly priced. Does anyone have this kind of setup at home? All thoughts are welcome.
