- I dunno WHAT the salesman was trying to tell you...but here's MHO on the
- the subject. Caching controllers are great... but they cost more than
- /standard/ controllers. What I'd do is buy a /standard/ controller, a
- faster access/throughput drive, and more system ram. This way YOU have
- control of how the RAM is being used. For example...if you're using OS/2,
- Windows or UN*X you'll wish you had just a little bit more system RAM than
- you have (no matter how much you have). If it's locked up on the disk
- controller the disk controller is the ONLY thing that can use that ram. If
- it's on the system you can decided for yourself if you want it to do disk
- caching or anything else. To make a long story short "if you get a caching
- disk controller YOU LOSE THE OPTION of where the memory gets used."
