However, if you buy external USB hard drives, it's only about $20/TB, you have full random access, you don't need a fiber channel card, and if you buy a bunch of USB hubs, you don't have to change tapes every 1.5 TB.

IMO the niche where tape still has an advantage is pretty small these days.




The idea of making a rats nest out of 50TB of USB hard drives aimed at consumers is not appealing. They're not as durable as I'd like, either.


Well, my experience with backup tapes is not one of durability either but maybe that's changed in the intervening 30 years or so.


I can't speak to the old generations of tape, prior to 2000. The LTO cartridges seem fairly sturdy to me, and I haven't run into many problems with the media itself. Unlike hard drives, tape media is fairly insensitive to shock, which makes it easy to transport. I've seen cases of water-damaged media, cases where the leader pin broke off (and got taped back on, and the tape was successfully read), cases where tapes were physically lost, cases where the database recording the locations of tapes was corrupted...

...but data durability has been overall excellent, and compares favorably to disk.
