Do I need a raid for editing HDV?

I'm putting together an upgrade for a friend's computer. I've ordered a Pentium dual core 2.5ghz cpu, 2gb of DDR 2 pc6400 memory, and an asus socket 775 mainboard.

The question is, does he really need a raid to use Adobe Premier Pro 2 with HDV? He has a sata II 400gb 7200rpm storage disk besides his boot disk.

thanks

No.

I can capture, edit, and output HD on a laptop with only a C: drive. It's better to use 2 drives of course, and even partitioning the internal into 2 improves things a little. But RAID certainly isn't needed.

Get my test cards document, and cards for 625, 525, 720 and 1080. Thanks to Gavin Gration for hosting them.

To add as Alan says an external firewire drive at 7200rpm with no raid is OK for HDV.

I have also used a 5400rpm drive or my internal drive with no problems, certainly sata will be even quicker but raid on sata is only really needed for full 10 bit HD.

Personally I use a g-tech raid drive but have found it no different to a std 5400rpm drive for most of my editing.

Thanks for that guys.

The DDR 2 mem is actually PC2-8500. The only question left, and it would be used with maybe Premiere Elements, is will a 2.5 ghz dual core Pentium cpu be quick enough for it to even run.
My friend doesn't want to bank roll a monster PC, but wants to do a bit of movie-making to show to friends.

I can edit HDV on a 1.86GHz Dell laptop, single core, nothing fancy, with a 4500rpm single internal drive. It's a bit faster and easier on a 2.13GHz Core2 laptop with 5400 rpm internal and 7200 internal drives (yes, two drives in a laptop).

HDV doesn't really strain a PC at all. The HDV data stream is only 25Mb/s, same as DV, but you need to transcode it to something else for editing, so that you're not continually decoding the MPEG2. Edius has a wavelet coder for this which takes about 80Mb/s, still not a strain on drives or cpu.
