A new HP DDS-2 drive will run you about $400-500, and those are pretty expensive for that medium. With compression you can get up to 8 GB, good media can be about $10. With a CD-R and compression you can get about 1.2 GB, and good media can be about $5 (you can get cheaper, but it gets pretty flaky). So for DDS-2 media, you're paying about $1.25/GB and for CD-R you get $4.16/GB. The cost of the device to write it is about the same for both. DDS-2 media is pretty flaky, in my experience, so I wouldn't use it for Real Backups, but then again, CD-R is equally as flaky (if not more so). > CDs are so cheap nowdays that there is no sense for a rewritable when it > would be just as quick/easy to rewrite the whole thing. Whatta waste. If you're not worried about expense, why don't you save the money you'd be wasting on CDs and buy a DLT drive (mmm.... DLT....)? :-) Besides, it's not the expense of the media that bothers me so much, it's going out and buying it, but with a DDS tape I can just re-use it, and formatting is as easy as pulling out the de-gausser. Of course, you do miss one of my favourite uses of CDs: zapping them in the microwave. -- Brian Cully <shmit@erols.com> ``And when one of our comrades was taken prisoner, blindfolded, hung upside-down, shot, and burned, we thought to ourselves, `These are the best experiences of our lives''' -Pathology (Joe Frank, Somewhere Out There) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
