- I use a hardware cache in my IDE hard drive with no problems. However, the
- Computer Shopper ran tests comparing various caching controllers with
- software (RAM) caches and their surprising results were that in most cases
- the software caches were faster! When they compared the relativey high
- cost of a caching controller with the (then) low cost of RAM it made a
- pretty good argument for spending less and getting more.
