My experience with low noise fans is that they often move less air than normal fans.

I am getting about 3,5MB/s using the A3000's onboard SCSI.
That is in sync mode on a Quantum Atlas IV (7200rpm uw-SCSI)
With a SCSI2SD v4 it is doing about 1.1MB/s

I'm surprised that works. What kind of foil did you exactly use?
I would expect you'd need something like mu-metal to shield the magnetic field of the speaker magnet.


But great that it worked!...

I think A4000/40 means a 25MHz 040 in AIBB, not a 40MHz 040.
That would mean this accelerator is about on par with a 50MHz 060 in this test?
(Pretty good!)

To go beyond 14Mhz would probably be better done by a proper, modern pll.
But for a simple, old school doubler the 4046 would do the job.
