do i need SCSI

I am going to set up a PC for video editing, for editing video taken by
my DV. I was wondering do I need SCSI drive given that there is 7200rpm
UDMA drive ? Could anyone share your experience and offer me some
advise ? Many Thanks .

IDE drives will work fine for video editing, but the CPU is what does
all the works and needs adequate RAM to work with.

An AMD Athlon64 is an outstanding CPU and usually a bit cheaper than
Intel. Get the 939-pin version and check the specs of the motherboard
carefully. Some boards slow the memory down if you fill all the slots
with double sided memory. On a 939-pin board there are four memory
slots and they run in the dual-channel mode when populated correctly.

Make sure you have whatever drive(s) you set up, on a separate/dedicated
channel, as opposed to sharing with the operating system, and
applications. You want the editing drive(S) to be concerened only with
reading, and writing the video data.

But you just said UDMA drive. What drive is it? I have a 7200rpm ATA 100
drive that seems like it would do pretty well with video if it were
dedicate, but I haven't tried, as I do in fact have a scsi RAID 0 array.

You couLD always get one or two 10,000rpm raptor serial ata hard
drives, only problem is capacity, 74gb is the biggest available.

As such, a couple 7200rpm ata 100 or ata 133 drives in a RAID 0 array
would most certainly do very well, without having to compromise on the
size. I've got a WD2000JB. It's 200GB, and 8MB cache. It's very
quiet. For the money, rather impressive. Big Western Digital fan here.

SCSI will give you better performance, especially if you use 15K RPM Cheetah
HDs. However, you will only attain best performance if you have a 64-bit PCI
bus for the SCSI controller.

If you have only a 32-bit PCI bus and are not going to use RAID, UDMA 100 will
work reasonably well.

Today's modern budget-priced drives are fast enough, except
for very simple pass-through editing the drive performance
is a non-issue, especially with the DV already compressed
from camcorder (or whatever) and presumably recompressed in
a one-pass editing. Only with multi-pass on uncompressed
AVI is there a large benefit to high-performance storage for
"typical" uses.

Primarily video editing benefits from very big drives and
separate source and destination. That is, a pair of drives
not raided will be faster than same pair raided, providing
the work is split as i mentioned, a source and destination
on different drive(s). Of course 2 RAID0 sets would be
usefull, but 4 drives is often more than a casual video
editing calls for. This is in addition to a 3rd drive or
set for the operating system and/or any other uses of system
if/when jobs are to be ran in background while system is
otherwise used.

Yes, separate source, destination. Does not work for tivo though, but tivo
is not "video editing" per se. Still, it's tempting to think about how such
a system might be implemented.

I use a promise ata133 scsi card with a Maxtor 7200 ata133 80gig HD
for my primary editor and it does fine.
If your primary IDE is ata100 it should do the job though if you want
to save the bucks on a scsi controller.
If you've got the funds the 133 controller is the way to go for a
simple setup though. Runs much faster and gives you plenty of margin
to avoid frame drops.

Assuming the video isn't "live", streaming in from the DV,
there is no possibility of frame-drops, it's basically just
a file transfer that is limited in how long it takes either
by the source, destination, or interface speed... nothing
lost from already-captured video.
