<<Does anyone have one of these drives ? They hold 2-8 gigs of data. I
just want to know how fast they can fill-up a 90mm tape ?>>


The rated speed of DDS drives is 11MB/min of uncompressed data. With zero
compression, a DDS drive will take just over 3 hours to fill a 2GB tape,
provided that the system and interface are fast enough to stream data
continuously to the drive. Adjust the time downward by your average
compression factor, then upward for stop/start, and for backup software
that does not use continuous streaming.

IOW, "It depends". ;-)

FWIW, the "2-8GB" is not really accurate; the standard compression factor
used for rating DDS-DC, DDS2, and DDS3 devices is 2, giving a capacity of
2-4GB for DDS-DC drives using 90m DDS media.

<<And if you know - how much they are going for ?>>


No idea. These drives are obsolete-does anyone still sell them? New
copies of the replacement drive, the C1536, can be had for a little under
USD600. C1533s, the 4-8GB DDS2 version, start around USD800.

You might hang out on
