ide raid

Is it possible to have a four drive array
that is both raid 1 AND raid 0?

if so, where to start, to configure the array for a win2k server?

RAID 10 or 0,1
This RAID level resembles a combination of RAID 0 and RAID 1. The idea is to mirror a stripe set or to stripe a mirror. The effect is the same. Due to striping, the read and write performance is excellent, as long as no failed drive needs to be rebuilt by the mirror-process. The reliability is also excellent, because you still have a complete backup of your data on another drive. However, you require double the amount of drives than with RAID 0 to achieve the same capacity.

Thanks Vernon, that's exactly what I was looking for. I thought I had read somewhere that it could be done w/ SCSI drives, just didn't know if it could be done w/ide drives too.

Through your link I found that promise makes one that works w/ IDE. "FastTrak100 TX2"

Now one more question before I finish (virtually) configuring this new file server and move on to the "talk" w/ boss about funding.

Should I install a fifth drive to handle the o.s., and set the IDE raid 1-0 array as the storage area, or can I (should I) just place the o.s. on the drive array also?

I'm not quite sure which way to go, The array would be faster, but the separate drive may be safer. (Easier to secure)

Any suggestions are appreciated.


Thanks Craig
