Good question. Placing a SSD next to HDD's is no issue and PCIe Slot 3 & 4 work without issues in all reports. Regarding PCIe slot #2, the cMP video card should not present any issues relative to heat and only has reported issues with:
  • Earlier 128GB Samsung XP941's disconnect on deep sleep. Yes 128GB, it was the only version available for purchase in December of 2013.
  • Apple/Samsung SSUBX PCIe SSD's may connect at 2.5 GT/s vs 5.0 GT/s, limiting speed to the mid 800MB/s.

Hey, handheldgames, where can one purchase a SSUBX SSD? I've checked eBay, but they all appear to be the SSUAX version. What should I be looking for, and is there a better place to look?

Three sold on eBay around mid-day on Friday - I found two of them. You cannot find them by searching for SSUBX or any other numbers. Once you see a 1TB card listed, you have to look at the image and determine for yourself if it is the one you are looking for. That's what I happened to do anyway . . .

Ah, that figures. :( Thanks for the info, box185!
 
With Apple's announcement of the new SSD's that are "2X the speed" (AKA SSUBX) for the Macbook Air and Macbook Pro, we can expect to see these take over as the new standard on Ebay over the next year.
 
Yeah, Apple Based SM951/953 drives should get readily available over the next year.

Honestly though I don't feel that big of a difference between the old Intel X-25M drive and the MZ-JPU256T/A02 I recently installed.

Other limitations of the Mac Pro 3,1 is starting to rear its head.

Hello,

Honestly though I don't feel that big of a difference between the old Intel XM-25M drive and the MZ-JPU256T/A02 I recently installed.

Not sure it's just the 3,1... On my 4,1, I've had the same experience when going from my x-25m to a Vertex 4 in 2012. The benchmarks were significantly different, but the overall user experience was exactly the same.

But regardless of the Mac used, I think that those uber fast drives will only be useful for people that absolutely need the throughput, for example 4K+ video work. In day to day usage, I think that current SATA3 and PCIe SSDs are far from the bottlenecks, so going from one to the other won't make much difference.

I have both versions of the Sintech PCI-e adapters and both work exactly the same for me. I did find the adapter with the heatspreader alignment is a bit better, but the mounts for the blade are not perfect so the blade position is slightly off from parallel with the adapter card.

Neither of these card give me issues when plugged into any of the PCI-e slots and both register at 4 lanes and 5 GT/s. I am on a Mac Pro 5,1 that isn't flashed.

I believe I have the earlier version of the Sintech PCI-e adapter. It does not fit well in my 2009 Mac Pro. The screw holes in the adapter bracket force the circuit board too far inward causing the circuit board to be misaligned with the key in the PCI-e connector on the back plane.

I removed the screws from the adapter bracket and was able to install both the adapter and the bracket without a mechanical connection (precarious) Once installed, it was clear that the holes were not properly aligned.

I have looked at the images of the second version being offered on eBay. In those, the bracket appears to be different - the holes appear to be in a different position. I have ordered one for comparison, but I would be interested in hearing comments from others.

received the 13" 2015 MacBook Air about an hour ago. there's a special build of 10.10.2 on it (14C2043) and the system-profiler shows something interesting: on the left, between "Memory" and "PCI" it says "NVMExpress" :cool:

of course when clicking on this topic it says: "This computer doesn't contain any NVMExpress devices".

edit:
the latest 10.10.3 beta (build 14D98g) shows NVMExpress on the cMP, too.

Interesting. From Pike's Universum blog:
iFixit found a Samsung S4LN058A01-8030 controller on the SSD during their teardown of the new MacBook Pro (13-inch). That is the same controller that can be found on the Samsung SM951. The ACPI only version, and thus the SSD is not the one with NVMe support. It would have been nice if Apple had used the Samsung S4LN058X01-8030 (used for the Samsung SM953) but that is not the case. Apparently. This makes me think that the kext is there for a future update. Anyway.

Hello,

Eager to see what Intel has in store... No rumours?

In any case... If a 2009 MP can just about humiliate a 2013 MP with regards to GPU and drive speed, it's quite obvious that a "normal" 2013 Mac Pro tower would have absolutely rocked. Open-ended GPU possibilities, PCIe 3 SSDs, recent CPUs, native USB3, PCIe level expansion without external boxes, internal expansion for HDD space... Damn!

I'm not familiar with hackintosh pros/cons, but when my 3.33GHz CPU won't be enough (doesn't look like it's going to be soon), I'm seriously going to look into it.

Such a shame. I was on the fence about the new Mac Pro at first, but now it's just painfully obvious that the can design was all wrong...

SM951 available
Sleuthing the net, there is a supplier in the UK that has Samsungs latest gear: http://www.flexxmemory.co.uk/solid-state-drives-ssd/samsung-sm951-512gb-m-2-ngff-pcie-solid-state-drive-ssd-2280-mzhpv512hdgl-00000/

Whilst it's a UK supplier(grab another pint for some cMP top gear action), the blokes in the US can get the kit VAT free with a bit slower shipping.

If you can't wait for an eBay Apple/Samsung SSUBX, this is your chance.

Trim enabler Wowes with the SSUAX
If you use trim enabler for legacy SSD's, which we all should, expect an occasional grey do not boot screen, requiring some terminal nonsense to restore functionality. The upgrade to 10.10.3 beta rendered my 1Tb ssuax unable to boot without a manual jumpstart.

Final toughts on running in Stealth.
As macvidcards mentioned, why was there no press coverage on our new toys? Ask MR, Appleinsider, barefeats and thessdreview. I sent email tips to all the orgs when the SSUBX first surfaced calling out the Apple/Samsung delivers the Fastest SSD ever.. on EBay. Whilst Les from tssdr popped up in the thread, our findings were relatively stealth, enabling us to grab the kit as it showed up on eBay. Which turned out to be a good thing!

To be clear, are you saying that you had TrimEnabler running for legacy SSDs and this caused the problem with 10.10.3? OR... Are you saying that the 1TB SSUAX has a problem with 10.10.3? I'm thinking the former but I want it to be clear in my head, it's a little foggy right now from meds. :eek:

Yay ! You summed it up nicely. All of the "come on guys, it's not so bad" stuff has no meaning compared to what it COULD have been.

I'm fighting off the a upper respiratory virus as well. Lol. I had TrimEnabler running for legacy SSDs. That resulted with 10.10.3 not booting as it detected a unsigned driver.

I'd rather deal with the occasional option-r recovery mode terminal session than loose Trim.
