If you use software mirroring, you can do it all (I did it few weeks ago - I added another two 250GB disks to mirror of two 250GB disks, I now have 500GB RAID10). If you use hardware mirroring (if it's not real hardware mirror, switch to software mirror! see http://linux-ata.org/faq-sata-raid.html), if highly depends on what your RAID card(s) can do, or you can simply create software stripe of two HW mirrors, On 20.07.07 08:18, Alex Samad wrote: > Also raid 10 - will give you benefits of striping and mirroring, 1 hard > drive can fail and the other mirror will keep functioning. RAID10 (shortcut from raid1+0) is strip of mirrors, you maybe thought "the other _in_ mirror..." (raid0+1, aka mirror of stripes, is also possible, but has much higher probability of failing, when two disks fail) -- Matus UHLAR - fantomas, [EMAIL PROTECTED] ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
