Hard drives

[Stu]

For a non-linear editing system- what size and speed hard drive do you need? (or is recommended) I think the size needs to be massive (20-30 gb) but how fast (RPM) does it need to be??

[wisper]

Well, the exact number escapes me, but DV captures at about 10 minutes per Gig. Don't even dream of having a hard disk slower than 7200 rpm.

I'm working on setting up a non-linear system myself. I've just purchased a Maxtor 20-G 7200 RPM harddrive.
I hope it works.

As far as Hard drives go, for DVE (Digital Video Editing Systems)SCSI is always the prefered choice even though some budget systems suppliers are saying UDMA66 drives are fast enough the problem with these is there is still a significant CPU overhead which can interupt the smooth flow of data nesesary for DVE, SCSI does not suffer from this problem as most SCSI Controllers have thier own processor.
As far as speed of the drive is concerned go for the fastest your budget will alow, for only a small increse in price 10,000 RPM drives are available and just about all of them far exceede the sustained 15 MB/s transfer rate needed for broadcast quality video.
Capacity :- this one is a little more tricky to answer as it depends verry much upon the compression ratios used by your capture equipment, for example some of the D1 or supposedly D1 systems can eat up 8 or 9 gigs for every 3 minutes captured whereas most systems using compression of say 3:1 will use only 2 Gigs for the same amount of footage ..
Once again I can only recomend buying the largest Hard disk you can afford...
A note of warning tho .. some of the older
DVE systems on both the PC & the Mac suffered from a 2gig limitation in the maximum size of a capture file .. make sure your system dosnt suffer from this problem before spending your money.
