Charles Henrich: |Does anyone know of any zip drivers that are in user space, or behave |nicely in kernel space? If I do a copy to a zip disk with the ppb |drivers the entire system goes into space, taking minutes to launch apps |and other fun stuff. Any ideas on what I might be doing wrong, of if |this is "normal" ? Paul T. Root: |The SCSI would have helped, but the ZIPs are still slow. Something like |35 msec. A better choice is the Syquest drives. They are all around |10msec (9-13 depending on which one). I have 2 EZ135s (one work, one |home) and my friend just bought a SyJet (1.5 gig) that he uses as the |boot disk, 1 for Win95, 1 for FreeBSD, etc... I'm very satisified with the speed of my SCSI ZIP. Pretty fast IMO. We should qualify that the Syquest may be a better choice for speed. For other concerns, not necessarily. I've slipped and dropped a ZIP disk a few times, but haven't winced and prayed; just picked it up. The price of the disks is nice as well. |I'm not complaining about the speed of the ZIP drive, Im complaining |about the fact that it takes FreeBSD down with it.. Maybe a userspace |zip package would be better suited to the task than a kernel driver. I saw this same behavior when I was PLIPing between my two boxes here. I guess Ron's seen the same. This was on and ECP/EPP-capable motherboard parallel port BTW. Randall
