Mike -- if you posted that before, I'm afraid I missed it. And I think I would have remembered the trick about using the Finder to format at 1:1. A couple of comments -- my guess is that the SCSI utility formats at 4:1, maybe 3:1 since my linear performance improved by a factor of 3.6 when I reformatted at 1:1. On the other hand, when I moved the drive to the MacIntosh to format it, the CMS utilities said it was currently (after I had used the Apple SCSI utility) formatted at 10:1. Although I'm skeptical of that since that itself was already nearly a 2:1 improvement over what it was shipped formatted at. It doesn't surprise me that /RAM5 measures slow. (I too got a figure about twice as slow as my hard drive on linear read) -- there is probably a fair chunk of software in there to make it look like a block device, and all transfers are done with loads and stores (maybe a block move?) rather than DMA.
