My old Drobo, a second generation, 4 drive unit that I bought new in 2008 has been a faithful servant. It spent a lot of its time as the time machine backup and deep storage for music, photos, and videos. A couple of failed drives (easily replaced) and not a single byte of lost data in the 9 years that I have had this tethered to my Mac(s), it is hard for me to point out a fault.
