I've been using Exabyte drives on various systems since about the time Sun started offering them. In my experience, they are highly reliable and have excellent transfer performance. A couple of years ago I started working for myself. My systems in my home office grew too large for the surplus QIC-150 tape that I had been using; so I investigated the available tape backup options. Since it is coming out of my own pocket, price was a factor. Even a refurbished Exabyte was noticably more expensive than a Travan. BUT it makes up for it in cartridge costs. Travan cartridges were running $40 each as compared to $9 to $13 for an 8mm data cartridge. For a one month cycle of daily backups, the difference in cartridge price alone paid for a refurbished Exabyte 8505. (And I get the performance and reliability advantages.) DLT probably offers even better reliability and performance; but both drive and cartridges are more expensive. Exabyte 8mm seems to be the best compromise. On the other hand, if you need an auto-changer; the Exabyte systems are significantly more expensive than some of the DAT systems. (And physically larger.) But their multi-tape systems offer options like multiple drives sharing a single collection of tapes and a laser bar-code scanner for positive cartridge id. > If somebody uses a similar system on -STABLE, I would be very > glad if he/she could drop me a short note telling me what > he has got.

For 60Gb (uncompressed) you will need either an auto-changer or a pair of high-capacity drives. The Exabyte Mammoth is rated for 20Gb native, 40Gb at 2:1 compression per cartridge.
