Larry, On a drive that can do multiple head read/writes at once…certainly it's possible. Those aren't "consumer" drives. On a drive that can only read or write one head at a time…it's physically impossible. Don

Don, The Seagate Elite II is capable of at least 8 megabytes/second transfer rate. I don't know how they do it, but they do (RPM, for example, is in excess of 5000). We did not differentiate between 'consumers' and anyone else when we sold the drives. -larry

I have a ST 41600N, full height 1.6 (1.36) gig. Do you know if this is an Elite II series drive capable of what you've mentioned? Dave Elite MicroComputers – Flying high on AutoPilot

Dave, Its an Elite I; 5200RPM spindle speed, 5m/sec drive…SCSI-2 (not fast), 256k buffer. Not sure how it stacks up with other drives. What did you pay for yers? //Jonathan, \\//via AutoPilot

Alot less then you could ever believe….about $700 1 year ago. (DEALER pricing at that time was $2800) I know people, lets leave it at that. Dave Elite MicroComputers – Flying high on AutoPilot

Larry, I really don't think the Elite II drive is capable of 8MB / second, except from the drive's cache to the host. That is certainly only a momentary burst, and cannot be sustained. I guess I'll have to check the docs at work (we have them for just about every not astronomically priced drive around), but I believe the Barracuda's are the fastest Seagate SCSI drives right now. Seagate does have one parallel model (i.e., very fast) but that has an IPI (big blue type) interface. Could you tell me how you determined that it can do 8MB / second sustained? Thanks, Paul.

> Could you tell me how … Created and read back a 200 MByte file. -larry
#105119From: Paul HigginbottomJun 27, 1993 12:49 AM
Now what controller was this on that you read a 200MB file in at 8MB / second?
#105242From: John DraperJun 28, 1993 2:56 AM
I think it was made by a company called something like 'Perfect Technologies'. It was an S-Bus SCSI host adapter. -larry

Well, I checked out the specs of Elite II drives. Impressive, but nowhere near 8MB/second. Theoretically it could do 5'ish, but even then, not sustained. I'd guess closer to 3 sustained. Paul.

Fascinating. Unfortunately, I won't have an opportunity to duplicate the test anytime soon. -larry

Larry, Since you are familar with the Seagate Elite series…perhaps you can help me… 1. How well does the Elite I perform? Is it a "fast" drive? How would it compare to, say, a Quantum Pro240S, or a Seagate ST1480N (both in my machine right now). 2. What is a good street price on these babies? Thanks! //Jonathan, \\//via AutoPilot
#105003From: John DraperJun 26, 1993 2:49 AM
The Elite I was a good performer, and we never had complaints about speed. Don't know what speed it was, though. No idea on prices. I only fixed them, which consisted of replacing them when they failed. -larry
#105038From: Jonathan HirschmanJun 26, 1993 12:04 PM
Larry, Thanks for the information. The only pricing I found in Computer Shopper was for around $1700, although this sounded very high (considering that you can get a Fujitsu drive of the same capacity for a *lot* less, perhaps $400 less). Is there any reason for this pricing? Guess that is what I'm trying to find out. //Jonathan, \\//via AutoPilot
#105069From: John DraperJun 26, 1993 3:31 PM
I don't really know if there is a reason for the pricing difference or not. We sold the Imprimis product, which is what the better, faster Seagate product now are. They have always carried a premium price compared to other drive manufacturers, and for the most part (with at least one notable exception) have been worth their premium price. The notable exception is the Wren IV, 327 meg drive, which I consider to be worth its weight in lead. -larry
#105111From: Jonathan HirschmanJun 26, 1993 10:06 PM
Larry, Thanks for info. I expect that the former Imprimis product is considered to be a "premium" drive, and leave it at that. //Jonathan, \\//via AutoPilot
#105169From: Jun 27, 1993 5:24 PM
Jonathan, how satisfied are you with your Seagate ST1480N 426 MB drive? I am considering purchasing one right now. Regards, J0RGEN ….from DENMARK
#105206From: Jonathan HirschmanJun 27, 1993 10:34 PM
Joergen, How much are you paying for the drive? I was able to get the Seagates for next to nothing, so I am very satisfied. They seem to be about the same speed as my Quantum 240S, perhaps a bit slower…other than that, it seems to be a pretty good drive. //Jonathan, \\//via AutoPilot
#105295From: Jun 28, 1993 4:14 PM
Well, next to nothing is not quite my price. I have seen it at around $770 at a discount PC dealer, and tonight I just saw an ad from a guy, who wanted to sell his for around $540. These prices may be a bit higher than in the U.S., but recently hardware prices really have come down in this country. The A4091 SCSI controller is only $245 list price (with 25% sales tax it goes at $307). Regards, J0RGEN ….from DENMARK

Larry, I realize that anyone can buy pretty much any drive they wish. They can also buy pretty much any computer they wish…for the right price. I consider consumer drives to be those that cost in the $2,000 or less ball park. Joe Average Consumer won't generally put out $10,000 for a HD for his $1,500 computer. Don
#105004From: John DraperJun 26, 1993 2:51 AM
Well, I don't know what we sold the Elite II drives for, but it was likely more than $2,000. It was also pretty far under $10,000 (and those are Cdn prices). Seems to me our most expensive drives were in the order of 5 grand or so, but I'm really not sure. -larry
#105163From: Don Curtis/SYSOPJun 27, 1993 4:29 PM
Larry, I would suspect that Sun's prices aren't that much different than other major computer manufacturers. Our 1 Gig drives from NCR cost us $12,000 in an external case. They're made by HP. HP's prices for the same drive are similar. Don
#105243From: John DraperJun 28, 1993 2:58 AM
This wasn't Sun. Our drives were priced significantly below Sun's. We had no 1 Gig drives that expensive. -larry
