Editing 4K Footage: Where's My Bottleneck? 2.8 4-Core Mac Pro 2010, or Sata II (3gb/s) RAID 0, 3x 2TB WD Black Drives??

I'd love some input on where my bottleneck in my system. I can't live edit 4K GH4 footage, so I've been having to use proxies. I would love to upgrade my eSATA PCIe card to SATA III (6gb/s) and upgrade my RAID0 drive setup, but would that help if I've got an oldish Mac Pro (Mid-2010, 2.8 GHz Quad Core Intel Xeon, 16GB RAM, 240gb SSD boot drive, separate RAIDs for project files, raw footage, etc.)

Any help would be appreciated! Thanks!

simple -
stop using your eSATA card. Buy an 8 drive RAID array with a miniSAS host adaptor card (countless ones advertise right here on Creative Cow), and your problems will be gone. Why - because your current drive array is not fast enough.

I agree with Bob completely, and I'm not sure exactly what the bitrate is of your 4K material, but I can assure you, you most likely have more than one bottleneck.

1) (3) SATA drives in an older 3G eSATA enclosure with an older 3G controller striped as RAID0 is most likely not providing enough throughput - 1) eSATA is both old and slow; 2) you don't have enough drives striped together for high performance, an 8-drive 3G eSATA RAID only generates between 315 and 400MB/sec throughput, 3 drives is most likely only giving you 100 to 150MB/sec.

The new 6G SATA drives are MUCH faster than the old drives, installing just two of them internally in my 2008 Mac Pro generates Reads of 365MB/sec and Writes of 404MB/sec, and that's with the internal 3G SATA bus on the motherboard. You might want to try stripping three together in your SATA enclosure, but even that may not do the trick, depending on the bitrate of your 4K material. FYI, a newer 8-drive SAS array will generate an average of 1000 to 1200MB/sec - that's probably what you really need.

2) Have you replaced your old video card with a newer GTX 680 or 790? If you're editing with Premiere then you most definitely have a bottleneck there.

Thanks both of you for your advice!

The video card has been updated, it is an ATI Radeon HD 5770, with 1024 MB RAM. It was of course updated before we moved over to Adobe Premiere, otherwise we would have gone with an Nvidia.

I am using new drives, 3x 2TB WD Caviar Black, RAID 0, so it's of course the external 8-bay enclosure and RAID card that is the issue. I'm using a RocketRAID 2314.

Using the Black Magic Disk Speed Test Utility, this 3-drive RAID 0 is testing at 255 MB/s write and 290 MB/s read.

Alternatively, I have an internal RAID 0 in my Mac Pro, that is 2x Seagate Barracuda 3TB 7200 rpm drives, and that RAID 0 tests at around 230 MB/s Write, 240 MB/s Read.

I know that upgrading my graphics to an Nvidia card would help, because of Adobe's optimization for Nvidia cards, but if I went with SAS on my external RAID 0 setup, would hit a new bottleneck with the Mac Pro processors? Again, a Quad Core 2.8 Ghz Intel Xeon, Mac Pro 2010.

Additionally, I have to weigh these upgrades in with the possibility of getting a new Mac in the next year or 2, or building a Hackintosh if Thunderbolt 2 isn't sufficient.

Thanks again for all the advice!

take your drives and stick them into a miniSAS 8 bay drive array with a miniSAS host card from Areca, ATTO or Highpoint, and your problems will be gone.

Or stick them into a thunderbolt drive array, and plug them into any Thunderbolt 2 based Mac Pro, and you will be able to do what you want. Stop that nonsense with the Hackintosh.

Is there a reason that I should go with miniSAS card and enclosure, instead of SATA III? I've tried (briefly) looking for an answer to that on Google, but didn't find anything definitive. Might have just missed it though.

An 8-drive SAS or Thunderbolt array will deliver two to three times more throughout than an 8-drive eSATA array.

And I sense a little confusion. You should still be able to plug in 6g Sata III drives into the 8 bay chassis, just make sure it has a 6g backplane in the enclosure to get the speed out of the drives. Then that connects via miniSAS cable to the SAS card in the computer. David Weiss at Promax, among others here on the Cow, have great options for this.
Good Luck!

Hey Todd!

Thanks for the nice plug, however, for the record, I am no longer in equipment sales, having instead rejoined the creative side of the biz once again, and currently co-producing and editing a feature-length documentary.

Meanwhile, hope you're doing well...

HA! I didn't even notice the new sig line! Good for you David! You gotta do what you're called to and enjoy it!
Best Wishes!
