The hdds don't have to be made by the same manufacturer, they can even be PATA and SATA hdds. The only problem would be one of the hdds being too small in capacity to hold the contents of a larger hdd. I found a decent article on RAID configurations and installation tips, you can read it here.

Be advised also that if ANY of the discs in a RAID 0 go bad, all data on all hard drives will be unusable.

If you need to do a RAID 0, I would advise you to also do a RAID 1, for redundancy.

Good luck.

modern hard drives are so fast already there are few if any good reasons to use raid stripe, I gave up on it 3 or 4 years ago after losing everything a few times because of a bad run of hard drives

one client had a lot of problems with raid mirrors

The failure of just one drive will result in all data in an array being lost


Should never be used in mission critical environments


this is what I learned about raid stripes

If I was going to go with a RAID I would go with RAID5, if one of the drives goes down you don't lose any data and the system can keep functioning. This requires at least three hdds.

I actually tried to understand the stripe and mirror part by only using 3 drives, parts of it made sense.
The old style method seemed best, buy 5 identical drives, 2 are striped, then mirrored with 2 more, the fifth is a spare for when and if one dies.
