Hey eveyone got a interesting question..... I am upgrading my system tomorrow and need a little advice.... In my currant system I have 5 hard drives. 2x 80 gig Seagate SATAII drives ( RAID 0 ) C: Drive) 2x 250 gig WD SATA 150 drives (RAID 0 ) Media Storage) 1x 300 gig Maxtor SATAII SATdrive (System Backup) As you can see I use the above 2x 80 gigs in the RAID 0 array for my system disk (Windows XP) Sitting on my storage shelf I have a 74 gb WD Raptor drive that I was interested in using when I set my new system up tomorrow. However I wanted to know if I would notice any increased performance using the single Raptor drive for Windows over the SATAII RAID 0 Array...... Id prefer to keep using my two 80 gigs in RAID 0 but (being 2xtimes more space then the raptor) if the single Raptor will compliment my new Core 2 Duo E6600 and DDR800 better I will probably use it. Any opinions would be great..... Thanks in Advance. !!!!
