[2] RAM: tests done with ASDG RAM attached and active for RAM: use.
[3] VD0: tests done with 2MB recoverable RAM disk, nearly full.
[4] Scott Turner's MicroForge and custom driver results. ST-225 formatted
at 10M, 87% full, MFM encoding, 65ms.
[5] Supra 20 MB Hard Drive tests performed by deb! Christensen. 45% full.

Timing by Steve Plegge.
[9] C Ltd 20M tested with the October 87 PAL and SCSI.device. Disk 60%
full - and plenty fragmented. 20M Rodime. Timing by Steve Plegge.
[10] C Ltd 135M tests done by David Salas (RLL Micropolis 5.25" HD, 28ms).
[11] Sun-30/50 timings by Rick Spanbauer, and show what a high-performance
