What's the best VLB SCSI controller in your opinion. I never really played with them much, as I was more focused on EISA and PCI.
I do have an AMI Fastdisk, which I still haven't gotten around to testing. That one might be the only SCSI VLB controller with cache.
As far as I know, wide SCSI for VLB doesn't exist.
no wide or ultra SCSI for VLB that I know of
would say adaptec 2842VL is likely the best bet, only other card I know of is a buslogic one I've never tried (I have one... somewhere), and some random cards which used stripped down adaptec chips
Need identification for VLB IO card with IDE, Floppy, Serial, Parallel AND SCSI
another caching controller
another (NCR chipset)
in my personal opinion using a caching controller to read is probably of limited benefit on VLB or EISA because you have bus mastering already and most of the benefit would be found only doing certain types of burst reads, if using a modern SCSI drive, relatively speaking, the same reads would occur from the 8-16MB drive cache and you would only be benefitting getting faster reads out of the controller's cache until it's exhausted
writes would be where you'd benefit, at cost of stability inherent to VLB being kind of crap
