SCSI 50 pin - need a large drive

[Z Man]

I want to install a 36GB->73GB hard drive in a Micronet Data Dock hot swap
carrier. What is the largest 50 pin drive I can get? I need at least 36GB,
but larger would be even better. Space inside the carrier is tight, so I
don't think I can fit an adapter.

What form factor for
the drive?

Sorry, I should have specified: 3 1/2 inch.

RAM electronics sells an adapter that will properly attach to a 68-pin drive
and offer a 50-pin interface. That way you can use any current drive. See:

He's already stated that
he doesn't think one
would fit in the tray --
although he might be
able to kludge something
with an extra short
ribbon cable. That'd
make hot-swapping a bit
awkward, though....

There is very little space in the tray, but it is possible that a very small
adapter would fit. There are some on Ebay that look like possibilities.
However, a better alternative would be a 50 pin drive of at least 36GB, IF
such an item is available.

Any 68 pin SCSI drive should work on a 50 pin ribbon cable
as long as you get the 68-50 pin adapter.
(50 pin is just not as fast as 68 pin)
Drive size is limited by the SCSI controller bios, not cabling.

Bullseye, I just found that
one myself -- or at least I
found the model number,
finding the drive itself
(especially at a sensible
price) is another task
altogether.

I just opened up an Ebay search, and I'll check periodically. Retail
channels are asking well in excess of $200, more than I paid for a 250GB 8M
cache Maxtor EIDE drive.

A typical SCSI premium
at retail. You're
after something pretty
rare -- a modern drive
with an old interface
that amounts to a data
bottleneck by modern
standards.

No, not ANY, only those that have internal termination or
those that can initialize without the high-byte terminated.

In theory. Practice will be different.

Seriously - it actually has a higher internal transfer rate than external.

 

[Folkert Rienstra]

Seriously -

No kidding?
