Still true?
>From the manual for the Adaptec 2940U2W adaptor: "We recommend keeping your Ultra2 hard disk drives separate from your non Ultra2 peripherals. Connecting a non Ultra2 hard disk drive to the Ultra2 connector on the SCSI Card 2940U2W causes the Ultra2 SCSI segment of the SCSI bu s to drop down to Ultra SCSI performance levels (40 MBytes/sec)." For this reason, I bought a second adaptor for the SCSI CD-R that I put into a machine with SCSI Ultra2 drives. -- Neil Roeth -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/ TriLUG PGP Keyring : http://trilug.org/~chrish/trilug.asc
