Raid Questions

post #1 of 8
Thread Starter 
Ok two questions
1) Can I use RAID without a RAID card?
2) Can I RAID two different drives?

1) yes, many motherboards have this integrated. Figure out if your motherboard supports this. If not, you will need a card.
2) yes. It's best to use two drives of the same capacity, other wise the larger drive will be crippled and only allowed to use the amount of space as the smallest drive's maximum capacity.

1) yes. just make sure your motherboard supports RAID.

2) yes, but not recommended. When you use different drives, the smallest drive determines the RAID... thus, when you put an 80GB and a 250GB in RAID0, the RAID array will be 2x80GB. The excess 170GB of the larger drive CANNOT be used at all.

1) if your motherboard supports it. Even if it doesnt, you can get a really cheap raid card for under $50 if you aren't too picky about performance
2) yes, but performance will drop a little and your size will be limited according to the smaller drive. So if you use a 80 gig and a 300 gig drive, you'll only get 160gigs in RAID0 or 80gigs in RAID1, and the remaining 220gigs in the big drive will be unused.

Unless you use Intel's matrix raid

Ok, so should I RMA my 64.99 250GB HD and get a 500GB HD for 69.00?

I'd get another 250GB drive, slap those to in RAID0, and use the 500GB for data/backups.

NEVER rely on a RAID0 array alone...

Eh, I'll wait and see for prices then, I don't need more than 250 GB right now, its just that for 5 bucks more, I could get 250GB more, so I thought I should just return the 250GB...
