Does anyone have experience with the Wren Runner 330mb drive that APS sells? How does it compare to the non "runner" 300mb drive? Any what does the "runner" technology give you? I was also wondering about the drives Micronet is selling with the seperate nubus card for the scsi? How much more speed does this give you??? Thanks.

Joe Murphy asks about WrenRunner drives. The 330 meg WrenRunner is a Wren V type, with a maximum thruput of 1.5 megabytes per second on a iici SCSI port. I believe that part of its speed comes from being a short-stroke drive, ie it does not use the whole platter surface, but only the fastest (outer?) portions. The nuport SCSI board from Micronet does not speed up this drive, as the 1.5 meg/sec is its top speed. The new Wrenrunner II 660 drive is twice as big, and uses a faster spindle, I think 4400 rpm. When coupled with the Micronet Nuport, it will clock at 3.0 megabytes per second, or twice as fast. The original wrenrunner is fine, but older technology. For better thruput, the Wrenrunner II is a clear winner when used with the Nuport. On a iici without a nuport, Micronet has benchmarked the wrenrunner at 1.5 meg/sec, and the wrenrunner II at 1.75 meg/sec. Phil Noguchi

My understanding is that a 330 Meg Wren Runner is really a 660 Meg regular Wren on which only half of each platter is used. This cuts the area the head must seek over, and therefore cust the average access times, in half.

>I was also wondering about the drives Micronet is selling with the >seperate nubus card for the scsi? How much more speed does this give you??? I just got a MicroNet 644/NP at work, replacing my old MacinStor 650 (which is no slouch in the speed department - 16 ms access times). The initial impressions I have are that this drive is FAST. Performance in disk-intensive applications like Photoshop seems to be greatly improved. I can also notice the speed with which my 44 INITs load at start-up :-) I have to run some performance benchmarks for our sales department on Monday. I plan to run both hard disk test programs (like DiskBasher! and SCSI Evaluator) as well as real-world tests. When I have the results compiled, I will post them. Robert
