Has anyone tried the Diamond FirePort 40 or FirePort 40 Dual SCSI controllers yet? How are they? It appears to just be a NCR 53c875 controller, but their benchmarks are putting it ahead of the Adaptec 2940/3940UW. I'm not sure how good the 875 is versus the 810, but I know from my own testing that the 2940U kicks the NCR 810 around the block... On my home system, I was getting about 4MB/s read and write out of a Quantum Fireball UltraSCSI drive with the 53c810. When I plugged the same drive into an old 2940U my throughput jumped to 5.5 MB/s on writes, and 6.1MB/s on read.. I used iozone with a gigantic file (with 512 and 8192 bytes blocks - same effect). I'm in the marketplace for a new SCSI controller for a server system I'm building, and I'd love to go with the 875 based Diamond FirePort - the price is right. I guess I'm wondering why the 810 performs so crappily under FreeBSD, and if I can expect the same crappy performance from the 875 under FreeBSD? Is the ahc driver really that much better??
