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, Jamie Jamison ZymoGenetics, Seattle
