Just looking at the pictures side by side I'd say these are the exact same cards, they even bear the same markings and reference on the PCB.
 
I am thinking the same thing but I'm not sure and want to get confirmation from the expert on all of this :)
 
Thanks handheldgames. Do you think it is a viable alternative to the Lycom DT-120 M.2 ? I'm having a hard time finding the Lycom in stock.

One other question, would something like this work ?

SEDNA - 2 Port NGFF M.2 B + M Key SSD to PCI-E PCI Express 4X 4 Lane Adapter with low profile bracket

http://www.amazon.com/SEDNA-Express.../B00XU7N0JS/ref=cm_cr_pr_product_sims?ie=UTF8

I understand this is not two m-key ports but my thinking is, you could put a m key SM951 in as a boot drive and then a b key drive in as a scratch disk for Photoshop. Do you think there would be any performance penalty and is there a b key drive that you would recommend.

Doing a little research and would like to confirm it if possible. Based on reading these articles,

https://www.pugetsystems.com/labs/articles/Overview-of-M-2-SSDs-586/

B- Key drive are 2x PCI-E drives with a theoretical maximum throughputof 1000MB/sec.

If true would you even notice the difference using a b-key drive as a photoshop scratch disk on a Mac Pro 3,1 and would it impact the performance of the SM951. My guess is not as the B-Key on the above card seems to be connected via a SATA cable.

Perhaps I am misunderstanding how it works. I would value any input as this is all very new to me.

Hmmm........Would I be correct in saying the B-Key will be limited by the SATA II connection on the Mac Pro 3,1

From Sandisk's website

"SATA II (revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 300MB/s"
 
Thanks for the offer Lou. If I totally strike out I'll take you up on your offer. I'll let you know either way.

I'm realizing I may need to do two separate cards. Does anyone know if there is an advantage to using a separate scratch drive for photoshop like you would with a spin drive or is it completely unnecessary with SSD.
 
Again my .02. FWIW...

Working as an Artist with multiple large Photoshop files from 30mb to 300mb to 1GB+, there is a noticable increase in my workflow loading, saving and transforming content. While the loading of Photoshop is slightly faster, only the loading of LARGE resource files and continuous VM allocation is accelerated. Considering I open photoshop once, there is minimal benefit of acceleration in a task I do once in a while. All of my other tasks that rely upon LARGE file reading and writing, which there are too many to count, are heavily accelerated.

As a programmer, compiling and running an app in the iOS development environment benefits from the top end speed launching the iOS simulator and when validating iOS devices.

On average I reboot OSX about once a week at the most, loading photoshop, leaving it in the background. For bulk image processing I tend to use PhotoMill,which also takes advantage of the burst speeds.

Today, my system is generally faster and snappier than running with a SATA SSD. Booting from a 2014 1Tb SSD, the cMP boots faster than any 3rd party controller. Cold Booting from the SSBUX/sm951 generation has known cold-boot delays. Considering I bever shut down my mac, unless it's to screw with the hardware config, it's not an issue to me. Do i worry how fast GTA or Fallout 4 loads?

Benchmarks are great. They show known tollerances and performance envelopes of the technology. It's the dragstrip of our medium. Whose car is faster, which brand is better, whose disk is bigger. LOL... Beyond the workbench, is somewhere where us,the users live. How we use our systems rarely aligns with the usage scenarios.

In the end, we have been enjoying the next generation of storage technology for almost 2 years. Coming a long way from the XP941 128gb ssd, that on its worst day, held its ground, even excelling against the 840pro in Raid 0.

Happy new year everyone! May 2016 bring storage enhancements to our aging '09 mac pro platform based on an x58 derivative from late 2008. To date, the 09 macPro is the longest running System i've ever used. It's wheathered the test of time with upgrades and advances keeping it's performance in check with the latest and greatest tech Apple delivers.

Best!

Thanks for the in-depth response Thomas.

I am looking to do the upgrade from the perspective of retouching.

I don't play games on the system and want to create the best real world environment as I also work on very large files.

So my question is, are you running a separate scratch disk when working on those 1GB files?

I'm a little confused as to how exactly you have your system set up for working in Photoshop.

Thanks,
Rory
 
Huge thanks for the feedback and info!
It's pretty fascinating that we haven't been able to
take "full" advantage of all the power and speeds of the tech.
Good analogy with the race car and driver.
 
^^^^This is a x4 card just like the Lycom card. therefore AJA performance tests mirror the results of the Lycom. The card runs at the same temp at rest somewhere near 86º F and at load creeps into the 90s. It resides in Slot 4, I didn't try it in Slot 2 because it is a x4 card and if it worked correctly in slot 2, there would be no benefit. The card is vented in the rear, and there are white LEDs surrounding the card that shine out the vents in the back. The part appears to be well made and I'm happy with the purchase. Installation of the SSD into the card was a breeze. Seems to work as intended Not much more to say.

I used the lycom with a SSUBX 512GB for about 6 months or so, and heres what i found;
very fast, no question about it. very very fast.

but unstable, not in the sense of that the card turns off or freezes or anything like that.
but that very occasionally, when the mac pro has been turned off, booting it up results in a grey screen, cycling the power lets it boot straight into whatever OS I have on there but it because a problem so often that i ended up changing what i had a round a bit.

So I sold it for a pretty penny and bought a different SSD (SM951) with this adapter http://www.ebay.co.uk/itm/321946526574
And I couldn't be happier, fit and finish are better, I couldn't even install the lycom adapter with the rear plate as the card wouldn't fit in right.. so i just had it in the slot kinda limp. :(

regarding the SSD i must say that besides some initial trouble with trying to get Windows to install on the second one i bought I've had no issues with it at all, and its significantly cheaper than the official apple part; now even trim is supported on 3rd party disks, there no reason to go with a apple part..
