I'm researching the purchase of a new library with LTO generation 4 tape
drives and am interested in using the on-drive encryption to encrypt my
backup tapes so that if a box of tapes ever falls off of the Iron
Mountain truck I'm not having to explain things to the board of
directors and legal, update my resume and/or both. The spec sheets for
the LTO-4 drives that I've seen claim throughput of up to 120Mbps, but
as we all know the devil is in the details and for all I know that
throughput could have consisted of writing extremely large files
consisting of nothing but the letter "e" to tape, without using
encryption. Has anyone upgraded to LTO gen 4 yet who is also using the
on-drive encryption and if so what kind of throughput do you see on
average. Any real-world, real-life information will be greatly
appreciated.
 
 
Thank You,
