Raid0 - - as in ZERO? NO, that's just wrong on so many levels..... Raid 0 just _increases_ your chance of data loss by the number of disks you have. (Loss of any 1 disk can cost you the whole array). Go raid 1 or raid 5. Either will run right thru a single disk failure. Throw in a hot spare, and the system will probably recover from the failure before you even know it happened. And at least evaluate software raid. Its not dependent on late arriving and often flaky controller drivers. (There are still reports of raid controller problems in SuSE 9.1). I've been using software raid for about 5 years now and I really like it. Due to a power surge I had to replace one of the disks, and the software worked perfectly. Yes, it takes a tad more cpu power, but never exceeds 1% cpu on some pretty wimpy hardware. Software raid also allows you to mix scsi and IDE devices. -- _____________________________________ John Andersen
