Large (> 600 MB) ESDI disks are now available for under $3K
(for example, from CDC and from Maxtor).

I am looking for information from people who are successfully
using such disks on the IBM RT running 4.3 BSD.
Specifically, I am looking for the following:
1) Good and bad experiences regarding the reliability
   and performance of the disks.
2) Description of the parameters used to format the disks.
   Any problems in formatting the disks using the standard
   utilities provided by IBM.
3) Sources for these disks at low prices (for an academic institution).

If there is interest, I will summarize the info I receive
in comp.ibm.pc.rt.

I know of one person using a really large ESDI disk on an RT w/4.3. He
has a Wren VI (780M) disk. The problem is that it is not supported by
any of IBMs normal controllers because it is too fast, so he uses a
prototype controller (HESDI I think). I suspect that many of the disks
would have a similar problem with controller speed i.e. the regular
FESDI controller would not handle them.
