This may be overkill for what most people, but it puts into perspective what one can do with
a RAID and a computer hooked up to an HD-SDI output,

Wow. Interesting. On a Mac it's almost fast enough to support a single stream of around 100 minutes... I didn't think they had it to that degree yet.

Not without its issues though; you only get the fastest speed at RAID 0, which means you've got four times as much exposure to losing your data as any single drive by itself, and I don't know if 187MB/sec is quite enough to handle the full HD-SDI signal and all overhead necessary... plus, again, that's only a single stream. And you only get that speed on a Mac; the Windows platform is limited to 160mB/sec; don't know if that'd be fast enough either.

again i'm confused. what do you mean the Windows platform is limited to 160MB/sec when i'm seeing 376MB/s reads and 328MB/s writes on my dual Pentium Xeon system using a Deckling HD Pro Single Link card with a 2TB Promax SATA raid with 8 250GB drives. below is a screen capture of the Blackmagic Disk Speed test. i'm using close to 700GB of drive space and disk fragmentation analysis says that i've got 42% total fragmentation with 84% file fragmentation.

my point is, it seems as if HD-SDI uncompressed capture is here and "somewhat" affordable. My dual processor system and 2TB Raid with Adobe Video collection software suite cost my company a mere $12k
