As I have an nMP on order, I was thinking about changing from my Netgear ReadyNAS PRO (on GIG LAN) to a Promise Pegasus2 box. A couple of questions: I read that Pegasus disconnects when used with a MBP that goes to Sleep, and does NOT reconnect on waking the MBP. It is necessary to unplug/replug the Pegasus2. This is a show stopper for me as I also want to be able to use it with my MBP. Has this been fixed by a firmware upgrade, or is it still the case? How can you upgrade the drives in a Pegasus2 without loosing data? In my ReadyNAS, I was able to migrate from 2TB drives to 3TB drives, just by changing the drives, one at a time and waiting for it to resync, without downtime. As more larger drives were added, the ReadyNAS increased its overall capacity, and I didn't need to copy everything to another storage, just to upgrade. Can the Promise2 do this? I think it is called "expandable" RAID, or X-RAID.
