Steve:
We use HardFrames on all the machines at work, typically hooked to either a
Conner 340 (40 meg half height), Conner 3040 (40 meg quarter height), or
Seagate-Imprimus Wren V (170 meg half height). The Wren has an average
access of 14 ms, the Conners somewhere in the over 20 ms range. The
HardFrame seems to still be a bit faster than the GVP series II
controllers, although the difference is not as staggering as it was before.
On the Wren, using Dperf2, the 256K buffer read was in the 800 kb/sec range
with the Series II. With the HardFrame, the same read produced a 1.2
mb/sec read. The speed differences decreased proportionally with buffer
size, but as I recall there was still a substantial difference even at 512
bytes. I wish I had the stats to display in this message, but they're at
work. If I get a chance (and remember to do it) I can upload them from
there if you're still interested.
