- Hmm.. kind of "cost" are you talking about? If you're
- talking about $$, you can get very large, very fast HD's for about
- one dollar per meg of storage (2.0GB SCSI, 9ms).
-
- If you're talking about computational cost, it's very very
- application-specific.. RAM, Disk (floppy or hard), and tape all
- follow different rules. And when you combine the two (ie, disk or
- tape with smart RAM cache, disk or tape with stupid RAM cache,
- etc) you can find all sorts of nifty complexities.
-
- I have some generic rules sitting around here somewhere for
- time-to-access different amounts of information depending on how
- the information is blocked, what kind of medium is used, and how
- much information is being accessed.. If you like I can dig'em up.
- (They may be in San Jose, in which case I probably won't get
- access to'em 'till after Thanksgiving).
-
- Incidentally, what's this newsgroup for?
