Disk upgrade ReadyNAS 104
Hello I have a ReadyNAS 104 with 4 x 2TB drives. I wants to replace all 4 drives with 3TB drives. I have taken a full backup to an external 2TB drive as I only had 1.39 TB of data in tot...
Since you have made a backup, it will be faster to replace all the drives at once and let the system do a factory default on them, then restore the backup. You'll skip the intermediate resyncs for 2 and 3 drives. Of course, if you need concurrent access to the data, that doesn't work as well
But if you have not yet purchased the drives or can return them, may I suggest you go with 3x4TB instead of 4x3TB? For about the same price, you get 1TB less to start (which you apparently don't need right away, anyway), but you can add one more 4TB later and get the full 4TB instead of having to replace them all again if you need another increase in space. The next expansion is thus much more economical.
If you continue along your current course one by one, replace them with power on. Order should be from most unreliable (based on any SMART errors, or the oldest) to most reliable. Otherwise, order does not matter. If you replace them all and restore the backup, do it with power off.

I agree, this would make the next expansion cheaper.
The 3TB drives I have are FREE.... so thats why I am using them.
Thanks for the info
