Gene, When I bought my Syquest I bought it from a Mac OEM supplier. It's a Syquest in an external case/power supply — the name on the box is Total Peripherals. SCSI cable out the back plugged directly into the external SCSI connector on my 3000 (and now the external port on my 4000/2091). I don't know if 2091s are still widely available. I got mine from my dealer 3-4 months ago. The 4091 is now shipping so that might be the way to go. In a 4000 the 2091 has problems. It can't DMA into 32 bit memory so it falls back to pio (programmed i/o — using the processor directly to read/write). There is a program that some one wrote (Mike Sinz, I believe) called MapBoard that will greatly enhance the performance of the 2091 on a 4000 — I use it and noticed a 10x performance increase. -sja
