I've been told (I'm sure on this list) that generally hardware compression is better than software compression. I throw that out for whatever it is worth. Paul (It would be great to get ~47G on a tape. I get about ~14G, being a different--DDS3--type tape, of course.) ->>In response to your m

hardware vs software compression

2002-02-25 Thread Carl Wilhelm Soderstrom
I've got an AIT-2 tape drive, which supposedly will hold 50-100GB. the tapetype that I found, seems to say that it's 43GB: define tapetype AIT2 { comment "AIT-2 with 230m tapes" length 43778 mbytes filemark 3120 kbytes speed 5371 kps } but what happens when the data is compressible? I'm doing li
