- My A3000 25/50 with 6 megs fastram runs around 850K/sec to 1M/sec depending
- on disk usage and fragmentation. Thats set up with 100 buffers and the stock
- Quantum 52LPS drive. Sling in a Quantum 240LPS and you can expect around
- 1.3-1.6 M/sec, sustainable. GVP's 040 for the A3000 doesn't have a scsi
- controller onboard, even if it did it would be slower than the standard one
- unless it was a FAST scsi-II controller.
- Dave Haynie said they have a Maxtor Magic drive in the C= software department
- that runs 3.9M/sec through the filesystem and 4.2M/sec direct to the driver.
- I don't know what particular drive this is. Perhaps Dave could post the
- model no. for us :-)
- The A3000 scsi controller is probably the fastest scsi controller you'll find
- on anything under $10000.
