RAID 10 or XRAID or RAID 5

[Punkwaffle]

Which is the best? I'm looking for reliability and speed. Want to be able to have at lest 2 drives fail and still be safe.
Which one is best to buy? I looked at the Buffalo Quad and it looks good, but I heard it takes forever to write files to. I also was looking as the NV+ from Netgear. Any reccomendations?

The only level listed that can provide this is a level 10 array (for certain, keep reading). You can also go with a level 6, but you'd need a proper hardware RAID controller to do it (FakeRAID, which is software based isn't good for parity based arrays, as it CANNOT deal with the write hole issues with parity based arrays = 5/6/50/60).

X-RAID (I presume you actually meant X-RAID2) may not actually provide that level of redundency. Check the product details carefully.
