Anymore I think you're going to find that the SCSI card is going to be the bottleneck for data transfer and not the SCSI drive itself. I think 1mb/sec
on a GS is approximately what the RAMFast is rated and most drives made
after, oh the mid 90s anyway, can do several 10s of MB per second and
beyond. So even allowing for seek time, etc. the drive is probably waiting
on the SCSI card most of the time.
Not sure what you are looking for in terms of size, but--
I have used some Quantum ProDrive 50pin SCSI drives with good results (80-700mb). These were the drive of choice for Mac systems of the day so
those you find will most likely be Mac pulls. Maybe I have been lucky, but
the ones I have used are very quiet. After playing around with a 7200 RPM
scsi drive that sounded like a jet engine and ran at a temp that was quite literally too hot to touch, I decided I needed to scale back a couple steps.
Currently I am using a Seagate Hawk ST32155N 2.1GB SCSI as my primary drive.
It is only a 5400RPM drive which keeps it quiet/cool, and provides far more disk space than I will ever need. This actually causes some issues with directory allocation on an HFS volume, because at that size, it stores in
min 32k blocks. So even a 1k file shows up as 32k used disk space on a ~2GB HFS vol. Again, still not a disk space issue unless I've got tens of
thousands of 1k files.
I have another GS with a little 80mb Quantum ProDrive LPS which is so quiet that the fan on the SCSI case is louder than the drive motor, and it runs
like a tank.
Frankly, if you plan on keeping your gs for a long while, just stock up on a few 50pin SCSI drives and keep them stored away in an anti-static bag in
case one of your primary drives conks out. I don't think anybody is making
50 pin jobs anymore so pick some up while they are abundant and cheap on
ebay. You can use adaptors to get 80pin, etc. drives to work with a 50pin interface though, so there will be future solutions. You should be able to
get them off ebay for under $10 including shipping so they are cheap to acquire.

Hello,
Any suggestions on a fast (and relatively inexpensive if possible) SCSI
hard
drive replacement for my GS/ RamFAST rev D? I'm looking for something
faster than the ROMdisk (Ramkeeper) I've been using for booting.
Any brand/mfg./model/vendor you might recommend?
Thanks,
Shawn
