Summary: I've had this paper weight for nearly 3 years. During this time, I've had to replace the hard drives in it on 4 difference occasions. This last time, I swapped the drive and during the 3 day rebuild that it takes if using larger drives, the OTHER DRIVE "failed" so I lost all of my data.
Terrific NAS for the price. Great reliability. A few rough software edges at first but then flawless for over 4 years!

Summary: I have had one of these running 24/7 since January 2010. There were a few firmware glitches in the first month or so that produced false heat warnings but the unit worked fine even then. After a firmware update it has been running and in daily use for over 4 years.
Summary: Drive functioned correctly for two weeks beyond the expiration of its guarantee. Procedure for resetting simply doesn't work. Repeated technical support queries went unanswered. The amount of time sunk in trying to get this NAS to simply function was off the charts.
Summary: You want to feel safe with a RAID storage system. Had this unit for a pretty short time. Left for a week and upon return found that both hard drives had crashed and were unrecoverable. The odds that both Seagate drives were manufacturing defects and would crash together is pretty slim.
