Specifically I have a quote from a local supplier for a CDROM, SCSI adapter and a 500MB disk. The equipment in question is Toshiba XM5301B quad speed CDROM - SCSI-2 Adaptec 2842 VL kit 32 bit to Fast SCSI adapter 540 MB Quantum Maverick Fast SCSI-3 512K cache 9.5ms disk I've been trying to find out: 1. Will these three actually work together 2. What is SCSI 1/2/3 fast wide etc - to try to solve 1 3. Is the quote really telling the truth about the disk. The SCSI-3 and 9.5ms access times don't tally with other adverts [Quoted access of 14ms]. Also I've got Rods post about the quantum range of drives. I am aware of the www pages at www.freebsd.org but at the moment our connection to there is down - although ftp works. In any case our ISP is having problems at the moment and retrieving stuff is really slow 35B/s-ish. Are the documentation pages available anywhere in the UK?? Thanks for any help you can offer.
