Most other 2TB have agressive powersaving features to be called Green drives. This can confuse raid/disk controllers and the disk gets locked out because it doesn't respond as the Controller expects. This is apart from any reliability standpoint.

Hitachi drives works very well in a RAID setting even with powersave features enabled, thus they should be excellent for Sooloos as well.

Also the Hitachi drives are mechanicly engineered to be put in large disk arrays because of their tie with IBM Enterprise Storage and not just single desktops.
