Hi guys
Compaq Prolinea 4/66, 486 DX2 66, only ISA slots, nothing better.
Motherboard's local bus IDE (not EIDE!), which if I’m correct should have a 5 MB/s speed (am I wrong?).
With IDE drives it wouldn’t be a problem as they were turtles.
But I’m using a nicely fast IDE to SD card adapter, and the SD card is pretty fast.
I never considered installing an ISA SCSI card, a SCSI to IDE converter, and a fast CF card, because of ISA slowness and bottleneck, but now I’m wondering if the old IDE channel is a bottleneck worse than the ISA bottleneck.
In theory a 16 bit ISA should get to 16 MB/sec, which, vs the 5 MB/sec of the IDE channel, should favor the SCSI ISA CF card against the IDE – SD card (please don’t focus on SD/CF, they’re similar, just the CF doesn’t wanna work on that IDE controller).
What would be faster?
The main doubt, I guess, is what's exactly the "IDE" mode of the motherboard...
Because if it's PIO mode 2 or DMA Single Word 2 it's already 8.3 MB/sec.
Thanks
