Computer newbies forum: PCI-X compatible with PCI?

RAID 0 for backup????? It's not fault tolerant.

With Raid 0 you are splitting the data evenly between two SATA hard drives...half of your file may be on the one and half on the other. Thus if one dies you're completely screwed...you lose it all. Raid 0 is not used for backup, but performance.

If you want two SATA drives, one a duplicate of the other, you want Raid 1. However, this only solve the issue of one hard drive failing physically. If your computer gets fried in an electrical storm or you accidentally delete a file you're again out of luck...the data's gone for good.

If you want to securely backup your data you want to use a portable hard drive, flash drive, etc. That way:
1.) You have a backup even if the computer bursts into flames.
2.) You have a backup even if you're robbed.
3.) You have a backup even if you delete the file from your computer.
If you don't use an off-site backup method then you're only protecting yourself from select incidences and are still in danger of losing your data.

Hope this helps,
