I have a RAID 10 setup with 4x 80GB SATA disks and a hardware RAID controller.
A few weeks a go we lost a disk and then a few days after that we lost another. I replaced
the disks and rebuilt the array...everything was fine.
My question is - was I lucky?
Can you afford to lose any 2 two disks in a RAID 10 setup
or does it depend on which combination they go bang?!
