RAID Question

post #1 of 5
Thread Starter 
Hey Guys,

Im looking into going RAID and I have a question.

I have a 400Gig 7200.10 Perp Seagate.

I have found a 320Gb 7200.10 Perp Segate for £45. Or another 400Gb for £80 (WTH)

Q
Does the HDD's both have to be the same Capacity for RAID to work?

A
Your up guys

No they do not but the Size will be 320x2=640 so you will lose 160gig of space with a 320 and 400.

Also, since they are different sized HDs, I would guess they use different number of platters. Their performance is slightly different and you take the performance of your worst HD in RAID.

It is best to use the same model HDDs in a RAID array although not necessary.

If your talking about RAID0 then you want the same HDD for best performance.
