Robert, I went to the site you mention, and looked at the drives. The STD12000N seems similar to what I've used. The backup software we were using did its own compression. The STD14000N-SB is similar to what the UNIX guys used. I feel comfortable with the 4mil 90m uncompressed 2GB drives, but please get several second opinions. I haven't used tape backup with FreeBSD all that much, and I don't want my inexperience to cause you trouble. The model with hardware compression is nice in some circumstances too. The UNIX heads at work like the hardware compression. Perhaps someone on the list can address hardware compression as well. Thanks, [RC] Oh, before I forget, if used for a full-tape nightly backup, I've not seen one of the HP 4mils live for more than three years. I personally wouldn't expect much more out of the Seagates. (There is only one 4mil drive maker in the world anyway. <GRIN>) But in my work environment, replacing a 500$ tape drive every three years was not a concern. If you don't run a full tape every night, I would expect that you'd get a proportionally longer life out of the tapedrive. When we reached the point that we had two dozen (4mil) tapedrives in the field, periodic failures began to be annoying. We eventually switched to DLT in the hopes that a simpler tapepath, and a larger tape format would translate into less wear and tear failure. (Equally important were the faster data to tape speed and the larger capacity. At one point we had three 4mil drives for one weekly backup alone.) (Please, no abuse from exabyte lovers, they didn't have anything comprable to DLT WHEN we made our decision to go DLT.)
