Looking to replace or suppliment my current HDD (200Gb Seagate Barracuda, full up) and I was looking at the WD AAKS series drives.

Would it be better to get a single 5000AAKS or two 2500AAKS from the point of view of speed, performance and redundancy?

Would RAIDing the two 250Gb drives together be of use or just unnecessary, and if so which level of RAID?

Many thanks.
 
I was going to put the Barracuda in a caddy once I'd transfered the data to the new drive and use that for my back-ups. Purely to keep the kid's photo's on really, can't afford to lose them.

I guess speed is more important to me at the moment...
 
Sod raid.

If a copy corrupts then your buggered either way.

My setup:

Main HD 1 = 500Gb
BU HD 2 = 500Gb - backed up everything every 24 hours
BU HD 3 = 320gb - external - only major files - every week.


Just need to buy my Mac Pro first :rolleyes:
 
Well, if you want something very, very fast, the two 250s in RAID0 will be very quick. Bear in mind, though, that the AAKS drives are very quick in their own right, so a single 500GB drive would still be quicker than your old Seagate and give you a lot more storage space. Personally speaking, if it were my family photos or anything and I didn't have copies anywhere else, I wouldn't trust a RAID0 array ever, and probably not even a RAID1. I'd Get the single 500GB drive and make sure I had a completely seperate backup (maybe the 200GB Seagate, or more likely multiple DVDs).
