The way I understand it, IDE uses a lot of CPU time if you have many
requests, SCSI uses next to none.. on one of our servers (file/print/
terminal) we have a 4-drive SCSI array and one 80 GB IDE drive for
temporary storage... when anyone transfers large amounts of data
to/from the IDE drive, the terminal services sessions start to hang--
and this is a dual-CPU machine.
Anyway, SCSI just does better for servers.. but can definitely eat up
your budget. You could start with the IDE drive--it will work--, then
depending on how many hits you eventually get, the IDE machine
may need to be replaced with a faster machine sooner than if you
started with a SCSI drive...

Yes,
With SCSI more then 1 application can access your hard drive at a time.
With IDE, only 1 aplpication can access your hard drive at a time.
So If you go with SCSI, then if you have 10 people request a map from your mapserver, then each persons request wont have to waite for the previous request to finish( on the hard drive).
If you plan on getting a ton of hits( people using your site), got with SCSI.

Hi,
I am setting up my map server on a shoestring budget and was
wondering whether a SCSI hardisk makes a big difference compared to a IDE- 7200rpm hd for
serving maps.
thanks
