I would like to better understand how hard drive controllers with dedicated cache utilized their resources. What was the most optimal caching strategy used by vendors (what to store, and when)?
Similar for IDE vs. SCSI? Was the cache used for reading, writing, or both? If the cache was used as a write buffer then it seem data might not be written to the hard drive before the machine might appear safe to power off.
