I want to know what type of video you are doing because we sure don't need that and we do high end video editing for National Geographic/Discovery/Smithsonian.
Unless you are doing Hollywood stuff, I see no need for half the stuff you listed.
More internals and PCIE slots? For what? Almost all of our clients are delivering tapeless now and on externals. Dual optical bays? Seriously? Fibre is a must if you are in a post house.
Seriously? We also do full DVD high end hollywood type authoring at my facility (have been for 10+ Years) and Blu-Ray authoring and we have no need for internal optical super drives.
You guys seriously need to unhinge yourselves from those internal drives...lol
I work for a small TV station, we can't afford a $30K storage array. My MacPro (2008 3.2Ghz 8 core) has:
Internal: 2x1TB boot drives Mirrored. 2x750GB random storage drives.
Added DVD Burner (our Blu-Ray burner is in another Mac Pro)
Factory DVD Burner
Video Card
PCIe FW 400 and FW800 Combo Card
Sonnet eSATA card
Backpane adaptor running a pair of eSATA drives (both 150GB Raptors in RAID 0) off the internal unused Optical Bay SATA ports. (Video Render 1)
The Sonnet card is hooked to a pair RAIDs. 10 Drives in a old CD Duplicator with a Addonics ports multipliers. One is 4x640GB Video Storage drive RAID, the other is 4X 500GB drives. The 500's are actually a pair of 1TB RAIDS, one for Audio Render, the Other for longer term Raw Video Storage. Finally 2 other drives in that external each have their own SATA connections to the Sonnet card (Audio Storage, and Graphics Storage.)
Fibre Channel card hooked to the legacy Avid MediaNet or whatever it's called, for the ooooolllld footage from before our final cut switch last year.
Plus about 5 firewire 800 drives for backing everything up, and a firewire HDV deck, and once in awhile a control surface for Audio Mixing. We shoot tape still (HDV) because like I said, we are a small station that can't afford new prosumer card based cameras. Man would I love some though. We still get a lot of stuff delivered on tape (beta, yuck) and DV format. We do shoot some commercials occasionally using a Pani P2 based camera and a DSLR, but the road warrior cameras are still tape.
I want internal stuff because my desk is already cluttered enough. I'm constantly burning 2 DVD's at once to deliver footage to people, both in data and video. We shoot a lot for the US Ski Team, and when the world cup comes to the USA other stations always want footage. Uploading 19GB over a pair of "Shotgunned" DSL lines (400K upload, max) takes awhile, so most of the time we overnight it.
And that's just my desk. The other workstations use some drives on my machine as cold storage for finished projects. Between packages, 2 live shows, and special feature 30 or 60 minute long form shows we crunch a lot of video. No it's not big hollywood studio stuff, but the sheer volume of footage going in and out is a hassle.
I agree the future is tapeless, but where do you store all that raw? We fill 6TB of hard drive space every 6 months. During the Sundance Film Festival which happens here, we were ingesting nearly 12 hours of footage and producing 6 hours of content (live shows, pre-taped shows, packaged shows) a day. While most everything we have is on tape, going to find those (usually poorly labeled) tapes, capturing, and editing takes forever, so we try and keep as much raw as possible on the drives for quick access.
At some point I need to setup a render station to take all the prores finished projects and downconvert to H264 for storage on Blu-ray discs. But that's not really a long term solution since any burned disc will eventually fail. I don't really want the expense of HDV backups, but it's the cheapest loooong term solution I can think of.
