goates,
Hard Drives are getting so reliable that there is little extra risk running on RAID 0.
"When you have a Striped Array and I drive fails, you have lost your data", is the main argument against using RAID 0. I always reply, "what happens with you use a single drive and the drive fails?" You lose your data too.
I have run RAID 0 for years without issues and enjoyed the added speed you gain in Disk Access. Windows is all about Disk Access.
I do have a backup drive in my comp and I back my data up to, should a drive fail one day. Any data I cannot live without is now backed up to a DVD.
If you want speed, a pair of 10,000rpm Western Digital SATA Drives on an SATA RAID 0 Array with a 16k Stripe is about as fast as you can get.
Take Care,
Richard
