Hi all: I'm looking for the fastest disk I/O possible under 386 UN*X on a 386 AT. Some people seem to like ESDI, others seem to like SCSI. I'm not really religious about it; I want to get what goes fastest. If you could buy any ESDI controller, which one would you buy? If you could buy any ESDI disk drive, which one would you buy? If you could buy any SCSI controller, which one would you buy? If you could buy any SCSI disk drive, which one would you buy? I'm really not trying to start a net.argument, so please respond via email. Brad Staff Zenith Data Systems uunet!zds-ux!bjstaff

SCSI - the Adaptec 1542A seems like one of the hottest controllers available. ESDI - maybe the DPT caching controller. -- Larry Snyder, Northern Star Communications, Notre Dame, IN USA uucp: larry@nstar -or- ...!iuvax!ndmath!nstar!larry 4 inbound dialup high speed line public access system

The WD7000fasst card is a real nice card that handles eveything that I have been able to throw at it. The software that is used, comes from Columbia Data Products and meets or exceeds any requirments that I have. I would recommend to anyone that is interested that they look into the card. I have installed the card and software into both ISC and SCO with very little hassle. The biggest problem was SCO Unix, it was a real pain and gave use the hardest time. -- Kirk Moore --- Bellevue, WA --- uunet!pilchuck!dataio!-------\ uw-beaver!uw-entropy!dataio!-----shiloh!kmoore shiloh --- Bellevue, WA --- (206) 562-1561(board) - (206) 747-5709(voice)

I just installed a 7000 FASST2 on my 386 running 386/IX 2.0.2 and using a ST-277N (seagate) that someone gave me. It works just fine... I have an ESDI controller as my primary drive and use the SCSI controller for a secondary drive. Installation wasn't bad although the automated script didn't work for me... (I have a lot of things on this system they assume you don't) but 10 minutes of manual labor and it was up and running. And if anyone is interested, I'll be testing a Exabyte 8MM tape drive soon. -- ----------------------------------------------------------------------------- "I never met a computer I didn't like," | David Mutterer (N2IDF) "---unless it was made by IBM.!" | {rutgers!}rylos!dave -----------------------------------------------------------------------------

I started this thread awhile back with the query about what SCSI and/or ESDI controllers and disks you all liked. Since email responses seem to have stopped, it is time to summarize the responses. SCSI controllers ================ Adaptec AHA-1540A/1542A - I got some favorable comments. WD FASST - I got one favorable, one mixed, and one negative comment. Mylex - I got one "I've heard it's good" comment. SCSI drives =========== Imprimis - I got some favorable comments. There was a suggestion to use drives that had read-ahead, as they were much faster. Newbury Data - I got a negative comment. ESDI controllers ================ DPT - I got two favorable and one "I've heard it's good" comment. Compuadd - I got one "I've heard it's good" comment. WD1007A - I got one very favorable comment. Adaptec 2322B - I got one favorable comment. ESDI drives =========== Imprimis - I got some favorable comments. Maxtor XT4380E - I got a favorable comment. Micropolis - I got some favorable comments. I thank everyone who responded. Brad Staff Zenith Data Systems uunet!zds-ux!bjstaff

Took them months to get me a driver that worked. It was working in (slow, 16-bit) Western Digital emulation mode prior to that. It is reasonably fast. Mine has the minimum 1-meg of cache. Here are some timings using Wren-VI (700 meg) drives, running ISC 2.0.2: dd if=/dev/dsk/0s1 of=/dev/null bs=1k count=32768 time: 2.3u 34.9s 0:24 154% and with a 32-meg file: dd if=/tmp/junk of=/dev/null bs=1k count=32768 time: 2.3u 41.7s 0:39 112% -- Richard Foulk richard@pegasus.com
