Dave,
I realize that the computer bottlenecks the data transfer to/from the
hard disk. What I'm looking for, if any one has the info, is some numbers.
Just how fast is data transfered over the SCSI bus to/from the drive?
Thanks!
Rich

As for other drives, well ask a tech guy at the appropriate company. David Whitney, MIT '90 Still learning about my Apple //GS {the known universe}!ihnp4!think!whitney and all of its secrets.

I might suggest people look at the Jasmine 50 and 80 Mb drives. For $1,349 you get a complete 80 Mb drive manufactured by Quantum. Granted you cannot yet use the whole thing, but it should not be too much longer of a wait before either ProDOS 16 supports larger volumes or Apple (or probably third party developers) release partitioning software for SCSI drives other than their own.

Here is another approach - note that while _I_ dont use it, many electronic
acquaintences do:
CMS has an 80 meg drive for about $1200, including the SCSI card. If you
chose the A2P model, it comes partitioned into 2 32 meg drivers (the largest
that prodos can handle at this time) and formatted for ProDos. I have seen
this drive advertised under $1000 ...

If you are a Coop member you will also get a dividend on your purchases. I have found it to work very well with my GS, but have some minor irritation with it. I would like to leave it turned off when my kids are running their software from floppy, but this makes PRODOS 16 hang while booting. I would also like to be able to scan for startup disks with the hard disk off and have the firmware skip to slot 6 but this doesn't work either. These problems should be able to be fixed in the firmware on the SCSI board. I am planning on calling CMS to get their view of this situation. Does anyone know what the story is with the (CMS) SCSI firmware? Paul Nelson tikal!dad!nelson
