[Matthew Freed] “Model Identifier: MacPro1,1”
It has PCIe slots, and will fit nearly any modern RAID controller. ATTO R680 and Areca ARC-1882x are some of the most popular ones.

Perfect – I didn’t know that – thanks Bob!
(Ken, could you please mark Bob’s post “as a solution”?)

[Ryan Holmes] “Today’s video cards can accurately display footage (23.976, 29.97, 59.94, etc.) to a computer monitor”
Does Adobe confirm it anywhere? (Don’t mean to doubt your words, just want to be able to back it up.)
Just up until recently (CS5?) even 8-bit color space wasn’t accurately represented with the YUV-to-RGB conversion. Adobe seems to be done away with it and now displays YUV natively, but I don’t see anything to the effect of color accuracy, frame rates, scaling. Far as I can see, I can’t even be sure I get true 1-to-1 unscaled display when I choose full res playback.

[Ryan Holmes] “For editing 5DIII footage and EX1 footage you will be fine as is. You don’t need another card.”
Unless you are submitting your output for broadcast (or 24p BD) and need to be 100% sure that occasional jerkiness of the video is the result of 24p-to-whatever-the-display-monitor-frequency-is translation and not something in actual video?
Am I way off thinking that with graphics-card-based-monitoring, there is no way to display 24p as smoothly as with video I/O and a broadcast monitor with native 24p, or at least a TV with a pull-down?

iMac with Thunderbolt? CineRAID 8050 is one such solution, up to 32TB raw capacity, 600-700MB/s. If it is the newest one with USB 3.0, there’s also ProAvio EB400CR – up to 16TB raw capacity per box, around 150MB/s.
Most important specs of direct-attached storage are three things: speed, capacity, level of redundancy (RAID0, 1, 5, 6), RAID6 being the best of them, if available.

What does the server need to do?

[Ken Brinkley] “It just won’t see both boxes at once.”
This is weird, and isn’t normal behavior. I’d call Areca support on this, and start drilling down on troubleshooting checklist, i.e. put just one drive in each enclosure, in various bays, see if they can be seen by the system at the same time, try a different HBA or RAID controller.

It should see both boxes. Are the drives initialized in the 2nd box (added to the first RAID set or set up as a 2nd one)? Windows won’t see the new drives unless you do that and if you set up a 2nd RAID set, you will also need to create a volume for it in disk management in Windows. If you add them to the existing set, you will need to “expand a volume” in Windows.

It’s probably fine as a safer and larger replacement for external FireWire hard drives, but Drobos are known to be slow and finicky.
The best setup for a Mac Pro for that kind of a capacity is a MiniSAS tower with a RAID controller – speeds in excess of 700MB/s (vs. 75MB/s on that Drobo). Costs: $500-900 for the RAID controller, $800-1500 for the 8-12-bay box, plus drives in RAID6, preferably enterprise class.
If you’re not looking for those speeds, and are fine with 75MB/s, Drobo Pro will likely work.

[benji brucker] “Moreover does Premiere request the full resolution file from the system, then once the file hits Premiere pull out 1/4 of the pixels? using 100% of the file size.”
Reading full file sizes, serving up (displaying) scaled down (e.g. 25%) version of it.
[benji brucker] “is this the idea behing Adobe Anywhere?”
Generally yes, the server preps the stream that is scaled down and compressed as needed, somewhat similar to “auto” setting on YouTube. The reasons are different though. For local playback, you may need to scale down because the computer or storage are not fast enough for full-res playback. With Adobe Anywhere, it’s mostly about the bandwidth.
(These are somewhat educated guesses, not facts. :))

Grass Valley ADVC-110 has been doing a lot of these conversions in the past decade. Captures into a DV stream.
Alternately, you could capture into H.264 at variable bit-rates, giving you more control over quality, with something like Video Recorder, or H.264 Pro Recorder.
