SCSI differences

[Tones007]

I'm planning on going with scsi in my next system coming up here in the next few months(when i get teh cash that is). I wanted to know if anyone could give me a good description of the differences with the ~$99 Adaptec scsi cards, and the more expensive ones. Thank you

Pretty simple.

The cheap ones (99 or less) are at best 80MB/s (Ultra 2 Wide) controllers. A decent Ultra160 controller will set you back 125-140 used and closer to 200 new. Depending on how many drives you'll be running...

Depends on what you want to do with your SCSI hardware. The most benefit you'll get from SCSI drives is that it uses less CPU overhead than IDE drives, mainly because the SCSI adapters do most of the input/output control.

CPU utilisation does not play a role anymore today.

SCSI HDs are important for
*)systems that run 24/7 for many days (heat extension recalibration)
*)if you need 10K or 15K RPM
*)if you need low seek times (small files, database access, etc.)


Edit: $99 Adaptec cards are actually Ultra at best, so 20MB/s. Get a Tekram controller, which is much cheaper but just as fast, or a mobo with an integrated adaptec chip.

Is Diamond still making scsi cards? They used to get pretty decent reviews with their scsi but were more affordable too.
