RAIDing 2 diffrent sized drives?

Dazz · 01-17-04, 05:02 AM

Just wondering?, I currently have 1x WD 80GB SE drive now if i got an 40GB WD SE drive and i set it to RAID-0 that means i still have 80GB space but is equ to a 14k drive in peformance?

IIRC, in order to use RAID, the two drives have to be identical, same size, brand, model, etc.

Ah crap, 160GB is toooo much for me!

I did the RAID-0 thing and found it to cause more problems than it solved. But if you really want to try it, get a pair of WD Raptor 36 GB SATA drives and RAID those for your OS, games, etc. Then have a separate 40 GB (or whatever size) drive as backup for programs, movies, MP3s and anything else.

I have 4 identical 60 gb drives. I have 2 of them in raid-0 configuration and the other 2 unraided. I use the unraided drives for drive image backups (1 backup per drive). The reason that I didn't raid the other 2 drives was in case I had a raid failure and needed to restore a backup. Just a little FYI...

You can actually mirror 2 drives which are of different sizes, the only thing is that the drives will only have the size of the smaller drive. So if you mirror a 40 gig and 80 gig, you'll be wastin g 40 gigs on the 2nd drive bu will have a 40 gig mirrored set of drives

why not just 0+1 them ?

that way you are striping and mirroring.. specially with 4 identical drives

because then you need a RAID controller that supports RAID10.

Yeah thats what i thought too but saturnotaku says otherwise, reason i am asking is that a little layer on i am thinking of RAIDing my drives and needed to know. the 40GB drive isn't all too expensive and would like extra hard drive peformance. 80GB to me is still ALOT, by the time i fill it i would of formated. I currently have a 10GB IBM drive as backup. Should be getting a DVDRW soon was looking at an 4x but thinking of a 8x so backing up 4.7GB won't be too hard and won't need the 10GB anymore.

RAID10. so, you need support for four drives. and in that case, no, he probably doesn't have one--I can't think of a RAID controller on a motherboard (short of some of the higher-end Tyan boards, perhaps) that support RAID10.

Yeah, I'm just using my ABIT onboard Highpoint RAID controller. My only problem now is that I now have 94 gigs of HD used on my RAID 0 drives so it is now to big to fit on a 60 gb drive. Anyway I've just been installing games since my last backup so it wouldn't be a huge loss if I had to restore from it.
