Single disk will be restored far faster than a whole raid array. Especially if you can do hotswap of your disks, well yes, hardware should support this ofcourse. Anyway, I do think that a correct combination of AFR and DHT will make up for that disk loss. If only Gluster could do data relocation as a node/disk goes offline. >Konstantin Sharlaimov RAID-6 isn't raid-5. Raid-6 has more parity control disks, that means it can do paralel reads from more than one disk and performance doesn't degrade as much as with raid-5. That's why I think you get your rstore fast - your disk is able to recive data fast enought to do writes at high speed: actualy 8 hours for 1.5TB is about 72MB/sec average write speed - not many disks can keep up such speeds all the time.
