The Travan is getting less than 150K/s by my calculation, which is only marginally better than my old SCSI QIC-150 (which of course only gets 250Mb on a DC6250 which probably costs more that the Travan media, so it wins there). > > (Benchmarks are great, eh? <g>) Exactly. Of course a DLT is overkill for most home systems (do _you_ need to back up 25Gb/night?), but great for big servers. DAT is good for serious home users and medium servers at up to 6Gb per tape at about 600K/s. Below that maybe the larger capacity QIC drives for up to a bit over a gig, and maybe then Travan. After that, anything you can scrounge :-) (old QIC, old floppy tape, maybe a SCSI reel to reel drive if you are completely mad)
btw, does anybody know what (if anything) the density code 0x04 is used for? My tape drive appears to accept densities 0x04, 0x05, 0x0f and 0x10, but mt just says unknown for 0x04.
