54000RPM Hard Drive Oh OK for SVCD? Im useing the Dazzle 2 and the AIW 32meg DDR Radeon

[khelms]

Okay for what? Capturing AVI at 480x480? Capturing and converting to MPEG 2 realtime?

Wish I could get a 54000 rpm drive. That would really smoke the 7200 ones I'm using!

I think U are asking for a 5.400rpm HDD right?

5400 rpm HDDs are enough to capture 720x576 25fps 48KHz 16-bit audio with video compressed with M-JPEG PICVIDEO codec or similar at <3500 KBytes/sec and audio non-compressed.

Of course that you CAN´T do ANYTHING else while you are capturing...

7200 rpm HDDs are good for higher rates like > 5000 MBytes /sec 8)

I have 5400 drives and have no problem capturing 704x576 MPEG @ 8Mbps! The only benefit of faster drives is in file transfer. I believe that you really need 7200 for DV Firewire capture as that is really just a big & fast file transfer rather than straight linear capturing.

You can use (most) 5400 drives with a firewire.

I hope so! I intend trying some firewire captures after Easter and i don't want to have to buy a faster HD.

My experience, for AVI either a 5400 or 7200 rpm drive is sufficient (I have one of each in my computer, I don't notice much difference between them).

What matters more than anything isn't so much Hard Drive speed, but CPU time used for compression.

That is, on "Uncompressed" or "Huffy Codec" captures to AVI, the CPU isn't doing quite as much, and can dump 10 Megs/Second easily, with no defects in the picture.

The same on an MPEG-1 or 2 capture would produce less quality picture, plus the CPU will slow things down further (the harder the CPU works to compress, the less time it has to keep up with the I/O to the hard drive).

I know this is more complicated an analysis than anyone needed. This is just my $0.02 on the subject...
