hey i am obviously completely new to this, but i was wondering if it were possible to "RAID" partitions on one hard drive? Say i were to slpit a hard drive into even fourths, could i then set it up to pull data off the partitions as one like RAIDed hard drives?


no specs needed just hypothetical question

Quick story - I provided consulting support for company with network. Their admin ran backups on the SAME TAPE every night. One night the drive failed while backing up. There's no redundancy in using one tape and they lost everything.

RAID stands for Redundant Array of Inexpensive Disks (now termed redundant array of independent disks). Initially there was one raid, now there are several types.

Raid 0 - Striped disks. Distributes across several disks improving speed. If one disk fails, all is lost (which is why you run backups). It's what I run on my workstation, but not servers.

Raid 1 - mirroring

Raid 5 - striped disks with parity

Raid 6 - striped disks with dual parity

Raid 10 - striping and mirroring

Raid was first envisioned to run with 5 disks. I'm striping with 2, and some require minimum of 3. You cannot run RAID with one disk.

You can only set it up with 2 or more physical drives. What you have is 1 physical drive and 2 logical drives and won't be able to RAID them.

Sorry GRock, but the answer is No. You can only set up a RAID array on multiple HDDs (minimum number required =2). See http://en.wikipedia.org/wiki/RAID for more information.
