Most people in town use TexCam for equipment rental.

It’s still running well in our 2009 Mac Pro on Yosemite, but in RAID 0. I haven’t tried putting it back in RAID 5.
It has, in a way, worked out well for us though because we were forced into “RAID is not a backup.”
So, we have all of the speed of RAID 0 on mini-sas and a completely separate (albeit slow) nightly back-up solution over an eSATA connection. The savings of using the NewerTech over an ATTO or Areca helped pay for most of it too.

You’ve probably already figured out a solution or a workaround, but I wanted to mention for others that this is most likely a latency issue from using RAID 6.
You’ve got the sustained throughput right, but when your drives have to seek around to grab frames from different areas of the disk or array that’s where you’re dropping frames.
I’ve seen some charts indicating that RAID 10 provides the lowest latency of the usable RAID levels.

Are you importing your files directly from the contents folder that comes off of the camera?
I’ve been having some issues with the metadata saving to large 20GB+ MXF files that get synced in Pluraleyes, but these files have been merged together in the Canon XF utility, not within my NLE.

Since it’s a Dell, check to see how much RAM that motherboard can support, but keep in mind with an older system, the type of RAM it needs (DDR2?) will be harder to find and could be expensive.
I’m not seeing a whole lot of bang-for-my buck with our Quadro 4000 and Adobe software. I would save your money and invest in one of the higher-end GTX cards.
Invest in moving your OS and applications to a Solid State Drive.

Tough call.
If you’re gonna stick with Mac, I’d go with a small 4TB RAID0 thunderbolt array (maybe that G-RAID Thunderbolt device?), and grab a cheaper USB3.0 4TB drive to back it up…. It’s a smaller investment that could be used in the field later.

We ended up ditching RAID5 for a RAID0 using this card and enclosure. Glitches are gone and speeds are over 800 MB/sec…. no protection for RAID failure though.

If you already have fast external storage, look at the Sonnet Echo ExpressCard thunderbolt adapter:

I bought one of these for an editor I work with, and it’s going strong. You’re basically looking at $350 ($50 for the cable, $150 for the adapter, $150 for the eSATA card) to use your existing storage, but you get the ability to add other express cards, like the CF card reader which really comes in handy in the field.
There’s not enough competition in the Thunderbolt RAID market to invest just yet….

Long-time reader, never responder decided to sign-up and reply on this one….
We’re using this card with a Stardom ST8-U5 to build four drives (Hitachi 7K3000’s installed in the lower set of the Stardom) into a RAID5 configuration for a Mac Pro 5,1.
I ran diglloydTools diskFill command on this array, and read performance starts off strong at over 440 mb/sec but gradually decreases to just over 220 mb/sec as the array reaches full capacity. Plenty of performance for our needs.
However, and this is a big however, we just started working off of this array, and having transferred about a terabyte of footage to it, I will tell you that most of the videos now have a glitch with some glitches lasting as long as seven frames. These glitches are not in the raw camera files or footage before being transferred, and diskFill reported no verification issues. It could be a defective NewerTech card, and I’m working on arranging a replacement…. but it’s something to look out for.
There is not a lot of information out there on this card, so if you’d like to know more, like AJA System Test results, just let me know!
