That makes sense now. DVCPRO HD is 4x higher bitrate, 100 Mbps, so that explains your 15 minute record time.
Yep that clears it up. By the way, is HDV comparable in quality to DVCPRO HD? I've never used an HDV camera (though I had the opportunity to use a DVCPRO HD cam for a day) and I am curious about how it stacks up against dvcpro.
Up-side is that eSATA is even faster than firewire 800, scales to RAID better, is quickly becoming common, and may well spell doom for firewire 800 peripherals (so you're not buying into obsolescence).
FW800 is on the way out. It will still be around for a few years, but it seems as though the cable set-top box industry is poised to revitalise firewire, albeit is a different direction than it has currently been delivered. Gone will be the 7-pin FW800. In will be Firewire over coax, and supposedly also the long-overdue FW3200, neither of which will be backward compatible with FW800.
But before you make your decision, I just want to let you know that USB isn't great for connecting an HD. USB disks use "bulk mode" USB transfers, which are suboptimal for certain types of disk accessing. I don't think USB was ever really intended to be used to connect disks.
I thought Firewire was moving to Cat-5e/Cat-6, not coax.
Probably both. For FW3200, 4-pair Cat6 is pretty much necessary, but coax is for the moment an easier solution for set-top-boxes. Going coax obviously drops some of the niceties of FW, namely the ability to send data and interfacing simultaneously, but I'll take ANYTHING that will keep FW alive. . . Seriously. . . it's the only high-bandwidth multipoint-to-multipoint protocol around.
yeah, I certainly don't want to use usb for the HD. FW800 seems like the best bet for me, it's not too much more expensive than FW400 so I think it's worth it.

Ah, never mind. I meant DVCPRO HD. different format.
