I'll side with jkieth.
The immediate answer to the original question is, yes, of course it should work. However, you have just told us the interface, not the tape drive. You also haven't said anything about your backup environment or needs.
There have been many arguments and discussions about tape versus disk over the last few years. Curtis Preston (see
http://www.backupcentral.com) famously titled a presentation "Seriously, Tape-Only Backup Systems Are Dead" at the 2006 Lisa/Usenix Conference --
http://www.usenix.org/events/lisa06/tech (scan down the page for Curtis Preston). However, if you listen to his whole presentation, what he is really saying is that for large installations, disk-to-disk-to-tape is the only way to get the performance and features that are desired. He's not saying tape is dead.
There are many many different environments and configurations for backups over a wide range of scales. There's almost never just one right answer. I also seriously doubt you can infer that people aren't investing in sata tapes based on a one day response lag on the forum.
