We have been running two SI9761 drives with their wonderful cache
controller for about a year.  We love them to pieces and have
experienced only one major problem.  About the time the warranty ran
out, one of the drives started popping up with spontaneous bad blocks
all over.  I believe this was in the spring :-)  It took SI a while to
sort out the cause of the problem - the drive, the cache controller,
and the CMI interface were all covering for one another.  Eventually, the
process of elimination brought us to the point of replacing the HDA.
It turned out that this same thing was going on at several other sites
at more or less the same time - and all with HDAs from the same batch.
We have had no problems since the HDA was replaced.

BTW, we have borrowed a performance monitor for the cache controller
this week and were pleased to find that our average hit rate is around
55% and our average request service time is running around 15 ms.  You
should see what happens during the boot fsck runs!!!
