Too late. I just heard Bob’s head explode from across the country.
BTW, it’s not performance that makes green drives a no-no in RAIDs. When you’re talking total MB/s, all SATA HDDs are pretty similar, no matter the RPMs. RAID drives have to work in teams and green drives are not designed to do that. They will make the RAID randomly go offline because the RAID controller will see drives taking too long to do certain operations and will think the drives have failed.

Interesting. I’d love to hear steve Modica’s thoughts on 10GbE performance.
Is SMB2 available for all versions of windows?

I totally agree that losing PCIe slots sucks. But this isn’t too different than the transition from PCI-X to PCIe. I had to replace perfectly awesome Kona and Fibre Channel PCI-X cards with equivalent PCIe versions without gaining any additional functionality. It’s the same here with your examples of BMD cards. But you have to decide which is more important to your workflow, upgrading your $1000 cards or $5000 workstation. Some years you have to do cards, some years it’s workstations and some years it’s both. And sometimes it’s OS platforms. Only time will tell

I can’t tell if you want a serious answer to this question or not.

You mention a Rocket in your setup. if you’re trying to playback 5k footage, you won’t get realtime playback. Check optimized playback when using a single card. Although, I’m not sure if this has the same affect with 4k output as 1080.
Maybe there’s not enough VRAM available for 4k. You definitely should have more GPU power than a Q4000 or 4800.
BMD 4k Decklink is only 4x. So leave it in slots 3 or 4 in the Mac Pro.

@ Jess – Apple sells TB to FW800 adapters for $29
I do believe FW800 will go away. it’s so much slower than USB3.
Thunderbolt RAIDs are cheaper than SAS, and faster than RAIDs based on eSATA port multiplication (limited to 250MB/s). I think single and dual drive USB3 enclosures will become the norm, along with Thunderbolt for the larger RAIDs. The Areca 8050 levels out around 900MB/s. So theoretically you could stripe 2 of them for 1800MB/s. Switching from SAS to Thunderbolt is an interesting proposition. I’m curious to see how it will work at the SAN level.
having said that, I don’t like the requirement to use Thunderbolt for all expansion. I’ve used a few Thunderbolt expansion boxes from Small Tree, Sonnet and Magma and none of them are as quiet as a Mac Pro tower. And that’s 3 more power supplies. The Promise SANLink has heat sinks instead of a fan, which is nice. But it requires a power supply that I’ve already lost.

But TB2.0 doesn’t compare to PCIe 3.0 speeds for GPU work. Maybe if you could bond the 6 TB ports together to feed a Cubix…
i think my head just exploded

woohoo, I guessed it! Juan, you owe me a beer. 🙂
But I’m definitely going to give Nate’s suggestions a whirl on my next session.

Thanks Nate. That’s a trick I have yet to try

hey juan
do you export DPX and then use a Mac to do transcodes?
