I am running three IDE drives striped using Windows 2000 striping and I get close to triple transfer speed.
If you want to read drive reviews look at these two sites: http://www.storagereview.com http://www.tomshardware.com The perfromance bargain right now seems to be the Western Digital WD1200JB, with performance benchmarks close to the 10K SCSI drives. Yes, SCSI drives are faster, but cost many times more for the same storage. �ke -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Laurie Solomon Sent: Saturday, May 11, 2002 9:39 PM To: [EMAIL PROTECTED] Subject: [filmscanners] RE: Re:Computer size: RAID >I'm getting a system with 1.5 GB of RAM and 2 80MB 7200 > drives (CPU: Athlon 1800+).

If I am not mistaken, I believe that the RAID that your motherboard supports in its hardware and BIOS is an EIDE RAID - not a SCSI RAID - and your drives are EIDE drives. EIDE drives - as far as I know - have not reached speads beyond 7200rpm yet; Hence, some of what is being said about 15000rpm SCSI drives and RAID arrays may not be applicable. The increase in drive performance produced by stripped EIDE RAID arrays is questionable with respect to if it is significantly improved or not. One can only try it with one's uses and see for one's self. >Opening and saving 128MB files > might be faster but would PS in general be faster given that > I assume there would be little need to go to the scratch > disk with that much RAM. Not really since much of the time consumption involves the CPU processing and not accessing scratch disks or RAM, unless one is using very slow hard drives and hard drive controllers. Once again it is more a question of the significance of the increase in performance and not if one exists. That is something you will have to determine yourself for your application. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of John Matturri > Sent: Saturday, May 11, 2002 12:07 PM > To: [EMAIL PROTECTED] > Subject: [filmscanners] Re: Re:Computer size: RAID > > > > > To carry disk performance to the max, go with > > > a striped SCSI array of 15000 RPM drives! > > > > Very expensive, though.
