There's nothing we can't argue about on the FCPX COW Forum

But it does 4k so nobody will ever find it useful. It's just marketing baloney.

Does anyone know if you could load these things with SSDs? And if so, what sort of performance you'd see?

Dan,
yes, you can load these things with SSD drives, and your question, is the #1 question I have when I get my hands on a Tbolt 2 interface - how fast will it go ! This is a critical question, and for me, will determine if the 2008-2012 Mac Pro can truly be retired.
Remember, you can get 1500 MB/sec with any 16 bay SATA RAID array, using a 2008 3,1 Mac Pro, so the benchmark for a new Mac Pro with Tbolt 2 is to at least be able to do that.

Bob - Do you achieve that with direct attach dual 8 Gb fibre channel? That is serious speed. It equates to 12 Gbs, which I know they have for fibre interconnects, but I've never seen on an HBA.

You'd get that with any decent 8x HBA as long as it's sitting in an 8x slot. Even with only 8 6G drives an an Areca card in an 8x slot you're getting beyond 1100 in Raid 6 mode.

Hey Frank! what's happening? Long time man!

A "little birdie" has told me that it is possible to saturate the 20 Gb t-bolt pipe with the 8 sled box. I didn't get confirmation of the type of drives or stripe. I would imagine it's got to be raid0.

20 Gbs = 2560 MBs

There has to be some overhead though.

Doing fine, thanks for asking Keith. Having a peek in here every now and then.
I think you'll see rates of around 1200 with TB2 on average, not much higher. It's still PCIe 4x at it's core and this is pretty much what initial demos of TB2 raids peaked at.
Which, of course, is very fast and sufficient for most people.

On another forum, someone as an aside without explanation emphatically p[osted, “Don’t buy a 6-bay array.” I had thought the Pegasus R6 might be a good match for the Mac Pro, but after your comment and that other post’s warning, I think this may be the rationale: a 6-bay array just can’t match the > 1 GB/s transfer speeds of a larger RAID array using 7200 rpm hard disks.

Bob,

I will be setting up an editing lab with Pegasus r4 raid enclosures (18 units) as the media drives. Do you have any suggestions for a security cage/enclosure to put them in to prevent drives from being removed and units stolen.

dimensions about: width 7.5" depth 10 " height 8".

This is for a High School production program.

Mac Pro, macbook pro, Imacs (i7); Camcorders: Panasonic AG-HPX170/AG-HPX250P, Canon HV30/40, Sony Z7U, VX2000, PD170; FCP 6 certified; write professionally for a variety of media; teach video production in L.A.

The embarrassing part will be when someone tries to insert a USB stick into it, thinking it's the CPU... meanwhile the other guy is pouring a beverage into the fan of your MacPro thinking it's an aluminum beverage holder...
