Raid

What are the advantages of RAID-5? How does it function and is it better than RAID-0 or RAID-1?

i believe raid 5 is essentially both raid 0 and raid 1. it has data striping but makes backups of your files as well (which in raid 5 doesnt slow down as much if I remember right), usually onto one or two backup drives. it's nice, but rather expensive since you'll need like 4 identical drives.

Is this also know as RAID 0+1? Or 0/1?

Yeah raid 5 is great if u r running a server. you have backups of you drives so if one dies you dont loose anything. on the down side it is a little more expensive to set up and I think its a bit slower. probly not worth it if your not building a server

So RAID-5 is basically RAID 0/1 without having to have 4 drives?

no you need 4 drives.

Yes, two for the mirroring and two for the stripping.

I thought only 3 drives were required for RAID-5? Am i wrong?

EDIT: Also, when you do RAID 1, does it show as one big drive or as 2 separate?

RAID5 - Block-level Striping + Distributed Parity
Similar to RAID4, RAID5 improves by splitting the parity information across numerous drives in the array (thus removing the write-performance bottleneck)
Like RAID4, striping is done at a block level (and the stripe size can be adjusted)
A minimum of three drives is required
Has a single-drive fault tolerance
RAID5 offers excellent read performance and good write performance (although improved in comparison to RAID4); should be noted that parity generation can introduce serious system performance degradation issues

From RAID 101
