I really worry about your staff if you have damaged hot swap anything. How many insertions are they rated for? According to its data sheet, a lower end Tyco/AMP SATA connector measures up against EIA-364-09C (i.e., "Mate and unmated [sic] connector assemblies for 500 cycles at a maximum rate of 200 cycles/hour.") Other relevant forces are on there, and you can read the rest if you're interested here: http://tinyurl.com/ybnacp7 Basically, if you break them, you're doing something wrong or you are buying equipment with counterfeit or excessively substandard parts. I wouldn't consider this to be on the scale of a plague.

Plus the cost of the tape drive (~$700), plus time, increased risk (longer backup duration means more risk), deployment flexibility, etc etc etc.

Yes, archival storage.
