2 Late for RAID?

Different drives, as long as same capacity/speed, are actually better though (more for RAID 1 or RAID 5/6 than RAID 0 though) because different manufacturers drives are more likely to fail at different times when placed under the same/very similar load, such as in a RAID setup. You wouldn't want your RAID 1 or RAID5 setup going along happily, then two drives failing at once because they were the same manufacturer and had the same lifespan!

Even from the same manufacturer it is very unlikely that two drives will fail at the same time.

With RAID it is possible for different drives from different manufacturers to be set up together, but the best results come from identical drives and most step by step guides will recommend this.

Suspend to hard drive rather than cold boot helps a lot if your only real beef is with windows start time

1 - Buy three more disks identical to your current one. (If you can't, get three with equal or greater capacity and identical amounts of cache to your current disk.)

2 - RAID 10 them all.

3 - Profit!

Oh, I agree, very unlikely - just more likely than drives from different manufacturers! Apparently I don't practise what I preach, either, all the drives in my array are the same. But bought at different times, and in my defence, they were the only 1.5tbs around..

Not sure about profit - it's deffo a more expensive way to do it, and IMO less secure! An external HDD to back up to would be better really, means if there's a power surge or something like that, chances are your backup will survive while the entire RAID array, and any other internal drives, get fried.
