Looking to build a new mach. Looking at a i-975 xtreme with a x58 mobo. Alot of memory using Win 7 64bit OS. But storage I have 1 WD VelociRaptors should I just get a cpl more and use them in a raid array or I have been looking at a cpl SCSI 15000 drives with a controller. SSD is nice but for the size an money I think it is kinda pricey but do or would they out perform the hard drives? Anythoughts would help thanks.
