You need to learn a little more about the parts of a computer. Perhaps go to Google groups, and read comp.arch for a couple of months, making sure you understand all of the references. Disk drives are about 6 orders of magnitude (1,000,000x) slower than DDR memory. It takes a few tens of nanoseconds to read a random address from DDR, a few tens of milliseconds to read a random address from a disk. Note that DDR isn't the fastest memory in the system, either -- there are the L1 and L2 (and sometimes L3) caches as well. -- Steve Watt KD6GGD PP-ASEL-IA ICBM: 121W 56' 57.5" / 37N 20' 15.3" Internet: steve @ Watt.COM Whois: SW32-ARIN Free time?
