With those 5 disks in a RAID5 array, you can safely replace any of them, without losing any data. > Throughput is a concern though. I currently was getting 50MB/sec over > the > network.

Remember that with a RAID5 data is read sequentially from N-1 disks (where N is the number of disks in your array). Writing can be a bit slower due to parity calculation that needs to occur. I would stay with the software RAID setup, but it seems you should try and read some more about it. Remember to use some monitoring tools like smartd and mdadm --monitor that will shout at you when there are problems. -- Cheers Michał (Saviq) Sawicz
