RE: disk cache battery story

["Doug Hart" <DougHart@xxxxxxxxxxxx>]

I can't agree, disk technology has done very well in the last few years.
Now we have 15,000 rpm Ultra SCSI disks 140Gig in size.  This is a long ways
from what we had 5 years ago.
Our processors now have huge L2 and L3 caches.

I don't know the specific answer....

But consider the rate of improvement of disk vs. the rate of improvement in
CPU's.

Disks just haven't kept up, thus the need to add caching.
