Here is a single Samsung 840EVO 1TB SSD on the Velocity DUO card in slot-3:
Have you recently done a "forced TRIM" on your SSD? Maybe with all the testing, etc. it simply has become full and hasn't had a chance to clean up the array.Now thats what I should be getting. Ive got the same Mac with the card mounted in the same slot, Ive even got the same drive.

No Raid. Left is an 500GB 840 EVO that I tested when I had a Solo x2, Right is an 512GB 840 Pro on a Duo x2. Virtually the same.

How does the Duo compare to the Solo x2 (solo has a 2nd sata port)
I could get a sata power splitter and run another drive off of that, right?
using something like this...

Yes, you can run a 2nd drive off the SATA port of the Solo x2, but it seems by the time you buy that adapter and all, wouldn't it be a cleaner setup to just have the single card DUO instead?
I have two SOLO x2's with one drive each, but that is to get a bit more speed out of the RAID set compared to the max allowed by the DUO. We could sure use a DUO with higher max bandwidth...why capped at 880MB/s?

I can see your read/write speeds. There must be something wrong with my set up. You ain’t the only one that seems to be running at full chat. What slot are you in?Agree with @dmylrea on the much cleaner setup (no cable spaghetti) in a MP with the DUO x2. User of the DUO x2 since the beta card I was very lucky to test-drive. Exchanged the beta with a final release card. Not the fastest PCIe solution ATM, but still very happy with the no-hassle install and usage icm 840 EVO SSD's using OSX 10.10.1 and Windows 8 Pro. Highly recommended.

Goodluck choosing your card!

In my cMP 5.1 (2012) it's in PCIe slot #3. Here are my test results for a Samsung 840 EVO 500GB SSD on J2 on the DUO x2 in Bootcamped Windows 8 Pro x64 non-RAID & NO RAPID mode!

So far the people Ive seen, (only a couple mind), with problems seem to be running Subsystem ID: 0x9182, Im 9230.
Apricorn mailed me a firmware update yesterday. Ive got to boot from a USB to install tho. Ill put it in my old DOS box for that.
I'm lacking the know-how about your "Subsystem ID: 0x9182, I’m 9230" issue. Would you mind explaining that and did you manage to successfully install your new firmware from Apricorn? Thanks!
Cheers
Whilst it didnt appear to solve my problem and none of the revisions or IDs have changed. I did apply the update by booting into Windows. Now when I did the flash I used a DOSBox not my Mac. Youll also need a thumb drive.
The process was;
Download the zip file here, (it contains a Win98 Boot folder, the flash files themselves and an HP Thumb Drive Utility).
1. Unzip the folder and place the three separate items on your desktop.
2. Install the thumb drive utility.
3. Run the utility as Admin. Select your drive from the drop down if you have more than one present. Set the file system to FAT32. Choose Quick Format. Choose Create a DOS startup disk. Click the button and choose the folder called win98boot.
4. Close the utility and open the thumb drive in Windows explorer, (itll appear to be empty). Copy the 1058 folder to the drive.
Shutdown the computer.
6. Restart with the drive plugged in and when you get the option to choose a different start up drive choose the thumb drive, (I got the option by pressing F12 during boot - Im not sure if you can do this from the Mac by option booting).
7. It will boot to a C:\ prompt. cd to the 1058 directory by typing cd 1058.
8. Type dir to make sure your flash files are there.
9. Type go.
10. Sit back and enjoy the show. (Itll be a short one).

Thanks a lot for your workflow and provided links. Appreciated!!!
Is my assumption correct that due to the installation of a NON-EFI GTX-670 I can't read out the "PCI" section of System Profiler?
Is there another know application to read out the "PCI" section of my MP 5.1?
Found the Terminal code:
Code:Last login: Sun Apr 26 14:38:57 on console You have mail. MACPRO:~ $ [B][COLOR="SeaGreen"]system_profiler SPPCIDataType[/COLOR][/B]
But even this gives me a PCI read out error. Any directions?
EDIT: the Terminal command:does give a good readout for USB.Code:system_profiler SPUSBDataType
Cheers

I have the 0x9182 Subsystem ID: and I don't have any issues with the Solo X2. The speeds are as expected at just under 500GB/s in BlackMagic Speed test.
Sorry to hijack. When you have your boot system running off the Apricorn Velocity Solo x2, does the Mac Pro runs warmer comparing to having the System running off the regular Sata bay?
Thanks
