View Full Version : Blizzard SCSI IV

So on the end of by blizzard 060 thesres a SCSI IV board... with nothing attached but a 50 pin cable.
What I want to ask is just hom much faster than my power flyer is this? I'm guessing it'll be sans the CPU overhead which is a good reason to use it, but will it be any faster transfer wise if I slap a good drive on it?
I know I could just try it, but I thought I'd ask to pass the time, the powerflyer really sucks though.

Advantage SCSI has is 10K or even 15K (rotation speed) drives, which makes them /really/ fast. Bottleneck will be the controller though...

Obviously it depends on the speed you manage to get out of the power flyer atm. It is said that power flyer can get upto 7-8 MB/s, but often the actual speed is much lower.

With good drive you get 8-9MB/s, in optimum conditions very close to theoretical maximum (over 9.5 MB/s). This is with 1-2% CPU usage.
Obviously this is just the maximum transfer speed. The seek speed affects the performance aswell. Older SCSI hdds are actually slower in this regard than modern IDE hdds.
But if you want the maximum of speed with the maximum of affordable Gb´s then get yourself an IDE-to-SCSI adapter so that you can connect a cheap 200 Gb IDE harddrive to a scsi chain :)
