I received some email concerning my post about partitioning my new
drive.  It really was a good deal (this is the new type of Quantum
Fireball ("New MR Head Tech"), quite a bit faster than the old ones)
for a 9ms external Quantum drive at $390 for 1080MB from ProDirect
(800) 524-9952.  This was a special, but I'm pretty sure they'll
still have them at this price for a few more months.  I'm in no way
affiliated with them; I'm simply a satisfied customer.

Be sure to tell 'em you have a GS, and order on Fridays! (shipping is
free on Fridays).  On my 8Mhz/64k GS with an Apple HS SCSI, I can
load ProTERM v3.1 w/o initing the modem in about 1-2 seconds (down
from about 4-6 for my Vulcan 40MB or SyQuest 44MB Removable SCSI).
Sys6.0.1 shift-boots in about 8 sec flat (can't wait to try it on
on a RamFAST [hi Kent!] and 12Mhz Zip!).

Here are some access times I've measured:



Here are some access times of various common storage devices tested on a
ROM 01 GS @ 8Mhz/16k (8Mhz/64k) ZipGSX.  The SyQuest drive is a 44MB
Removable hooked up to an Apple High Speed DMA SCSI card.  The Vulcan 40MB
is not the Gold version.  The Quantum Fireball is a 1080MB drive with a 9ms
average seek time.  Time in milliseconds!  Measured with ProSEL 16 v8.84

[The second number (in ()'s) is on my new 8Mhz/64k Zip]

*: When the RAMDisk was at 32k, the Random Read rate was 9.57ms.  At
128k, ate was 7.16ms.

Note: All RAMDisk measurements in parenthesis are with a RAMDisk of 1024k.
