Using Scsi to IDE adapter on 1230-Mk4.
I recently bought a scsi2 to IDE adapter which I have been using with the scsi card for my blizzard 1230MK4.
I've having a few issues with it unfortunately, mainly with speed. The onboard IDE is reporting speeds of around 2MB/s, with idefix installed (and an ide express adapter & 8GB compact flash card).
Using a fairly new 80GB ide hard drive on the scsi-ide adapter - and I get about the same speeds?
I understood the blizzard scsi card was meant to be a fair bit faster than the on board ide, even with an expansion board - scsi 1 is potentially 10MB/s?
So - I dug out an old, large 9.1GB ultra wide scsi drive and used that (noisy brute!) and I get 4.5MB/s, which is more like it. Probably the limits of the processor I'm using (030@50).
I've been using small partitions for speed checks (< 2GB) so there should be no file system quirks etc with sysinfo disk speed check.
I'm using a "IDSC21-E" converter card.
Has anybody else setup anything similar, or have any ideas why things are so slow using the adapter? surely a modern ide drive should be far more more than a measly 2MB/s?
