- I've added an external drive to my HP 9000/433s and it seems to
- be extremely slow. It may be that the drive is really slow, but I wanted
- to check if I've misconfigured something first. The internal drive is
- running about 2 to 3 times the speed of the external drive in tests I've
- run using Bonnie and iotest and it just feels slower when moving files
- around. The internal drive is an HP2213A (SCSI Coyote II) and the
- external drive is a Fujitsu M2263SA. I've got the Fujitsu configured
- with read-ahead caching enabled, as a SCSI-2 drive, parity is enabled
- and synchronous transfers are enabled by the host.

- I've tried running tests when I've had the system entirely to myself
- and gotten the same results as when there is a load on the system. I've
- also run tests when the Fujitsu drive had no files on it (it acts as the
- news spool normally) and gotten similar results.
-
-
- So, please tell me have I'd made some fundamental mistake in my setup
- that would explain a 2-3 times difference in performance between the
- two drives or is the Fujitsu m2263SA a "slow" drive when compared to the
- HP2213A?
-
- Thanks for any help you can offer.
