If not, perhaps you need to upgrade to an IDE Fireball :->. FireballTM's should have an iozone speed of about 5 MB/s for both read and write. I get 4.98 MB/s write and 4.67 MB/s read for `iozone 512 8' for an IDE FireballTM2110A with a 1/10-full partition at offset 649152, size 2951424 sectors. >Disks are both 4500 rpm. The JAZ is 12ms seek and the Fireball is >10.5ms seek time. Seek time is not the greatest, but iozone seek much. Bruce
