what is the best hard drive to use in a RAID 0 configuration

i was looking at western digital 400gig if it is SATA 3.0 or a raptor 10 000 rpm, or a maxtor 15 000 rpm!

also is a raid edition hard drive better for stability or not? :?:

8O I don't know much about RAID as I have never had that. However, RAID 50 is suppose to speed up hard drive thru put. However, using fastest sata harddrive 15,000 rpm is needed to really take advantage of speed up & worse, present computers are at maximum thruput for hardrives. So for all money, not much happens. This is due to fact that core clock is too slow to move data any faster than 80 mb/s INTO MAINBOARD, most do 20 mb/s.So look for core clock of 333 mhz/sec or ddr-2 at 1,333 mhz/sec. That stuff will start showing up retail next fall.Maybe then RAID controllers will be upgraded to faster THRUPUT IC CONTROLLERS too, so your investment will pay off in media quality & especially gaming, if whole system is upgraded to faster clock..Signed:pHYSICIAN THOMAS STEWART VON DRASHEK M.D. :cry:

Please correct me if I am wrong, however all 15,000 RPM HDDs I am aware of are U320 SCSI.

And SATA 3.0 doesn't exist yet.

Also RAID 0 is fast however the chance something is going to break is increased by a factor of N if you have N drives.

If you have 2 drives it is a factor or 2, 3 drives a factor of 3 and so on.

If money is no problem I would suggest using a Hardware RAID controller like the 3ware 9550SX series or Areca PCI-Express controller.

The 3Ware is PCI-X however so you need a high-end server or workstation class motherboard with PCI-X to use it. Similar hardware RAID controllers from ARECA and others come in PCI-Express versions as well as PCI-X versions and theoretically could be used on a motherboard with 2 fully functional 16x PCI-Express slots.

The 3ware 9550SX can offer 800MB/sec RAID5 reads and 380MB/sec writes.

Q2. How is the 3ware 9550SX different from the 3ware 9000 Series controllers?
A2. The 3ware 9550SX controller delivers over 800 MB/sec RAID 5 reads and exceeds 380 MB/sec RAID 5 writes, making it 200% faster than the industry-leading 3ware 9000 Series controllers. The 9550SX is a SATA 3Gbps (SATA II) controller, while the 9000 Series is SATA 1.5Gbps (SATA I).

I can show you some 3Ware 9500 benchmarks if you are interested.
