Those are *both* nowhere near the limits of a cheap hard disk.

Recently I used the MPW "Search" command (equivalent to grep) to look for
a simple string in a directory of text files. Each file was about 100KB to
200KB in size, for a total size of 45MB (about 300 files).

The search took 30 seconds, or 1.5MB/sec -- that's 2.5 to 3 times faster than
your numbers. The disk was a cheap Quantum 240MB 3.5" SCSI-1 and the
Macintosh was a Quadra 700 (25 MHz '040).
