If you need a firmware update, a SATA II SSD works just as well as a SSUBX and it boots faster. Now if I can stop buying unnecessary hardware, I need to buy a 970 pro as well. I just couldn't pass up a dual 5,1 cpu tray for $275.
Got a tip for us?

I won't bet on Apple revamping MP51 BootROM and it's not like MP6,1 firmware that only upgrades from the original Apple SSD.
I'd bet that you won't need the SSBUX later on, at least not for your cMP. Test a lot your new combo and when you feel comfortable with it, sell the SSBUX.

If people know how much we love and spend on cMPs… =)
BTW, did you see todays price for Intel NVMe entry level blade, Intel 660p 512GB? $99.

I read the review, but missed the price. Not the fastest SSD, but that's a great price. I like where the technology is heading.

I think thats the same level as WD Black G2, It will be nice to have 4 512GB 660p for a little more than one 1TB 970 EVO.

Yes.. but 2 of them in raid 0 is still slower than a 970 pro. A good option for PCIe 2.0 adapters.
Much faster than sata III at the same price.

You make a good point. Samsung is about to have some competition in the value segment.,
SATA II speeds should not be relevant in this thread except for comparisons.
With one 250 - 512 gb NVMe M.2 blade as the boot SSD and the other as a data repository .. .who needs SATA II ?
I have already relegated my HOT spinner HDDs to my USB & USB 3.0 external docks = more cooling space for the M.2 PCIe adaptor space.

On the insanelymac site you (I guess it is you) say you have a solution for the bless bug at the end of OS installation which prevents (system restart) booting from an APFS RAID, but you don't actually post the details—unless I missed them when reading.
Would you mind posting the exact details here of how you fixed this problem—nobody else, including the SuperDuper and CCC devs knows a fix.
Thanks
Addendum—or was the unexplained "solution" simply to use a single NVMe M.2 SSD on non-raided HighPoint 7101A card for booting?

you both made some interesting comments
another good use is for rendering or encoding
we know that the more we write to ssd or m.2 drives
the sooner the drives will start to wear out
I know the drives now come with very good endurance
but the ones that have older models can benefit from not writing too much to the drive
so simply by using ram disk we can prolong the life of our ssd or m.2 devices
believe it or not many people still uses mechanical drives
meaning that they don't even have an ssd on their system
an iram disk can speed things up a bit during certain processes
I have another trick that I find out a while ago
I might increase performance a little bit more than using just the average iram virtual drive
create a virtual iram disk
run a benchmark test
now go to disk utility and format that virtual iram disk to Mac OS journaled
you will notice that the drive icon will change from white to a regular hard drive icon
now after you run the benchmark again
the speed should be a little bit faster
I don't know if this works on a genuine Mac but it does works on my system
I have a phanthom 4 pro and I do a lot of rendering or encoding with FCP
those 4k footage come out stunning
I learned color grading etc
I love Mac OSand I can't wait for Mojave
[doublepost=1533617438][/doublepost]
thanks for that valuable info
I will try to find that app
"TMPDisk"
I only knew about iramdisk in Mac OS
I will take TMPDisk for a test drive
if it works better than iramdisk then I will use TMPDisk from now on
thank you

Well, my 1701A arrived early. I popped it in with the 970 Pro and cloned the primary boot drive.
Drive boots well... Reads at 2,800+ MB/s so far. Prolly needs to idle/trim a bit.
Writes, 2200+ MB/s so far...
All seems well, but I'm not thrilled with the additional fan noise. It's not that it's really loud, but I've gotten used to totally silent.
Okay, I've got some KoЯn playing, so I can't hear it all now
What danger would present by disconnecting the thing? I notice that the Amfeltec card didn't come with a fan (although it was an option).

Congrats on the Highpoint and KoЯn. As you mentioned, the volume of the highpoint is not not the culprit... It's the pitch of the smaller fan.
The PCIe 2.0 version of the Amfeltec was the only version without a fan. Silent, but limited to 1500 mb/s. Think of it like the idling sound a Hemi 6.2L. All your mac is missing is the flamethrower exhaust pipes.
The PEX 87487 is rated to a maximum temp of 70c. Like the 970 pro, it probably needs some form of active cooling. Excess heat slows performance and will shorten the life of the chip. The dual M.2 and quad 8x PCIe adapters from QNAP, using asmedia chips like the new board from lycom, also have active cooling in all of their pcie 2.0 and 3.0 solutions.
Well, part of the problem is that I started testing it with the side cover off. I was satisfied with the result, and pushed the Mac back to it's usual location on my DESKTOP about 18" from my right ear. Later I looked over to my right cabinet set, and saw the Mac side panel. After putting it on, it's not nearly as loud. I still hear it, but it's livable.
Put some music on, and it's gone.
Also, when the system goes into sleep mode, the 7101A fan shuts off too. Very silent when not in use, so that’s a giant plus.

Tomorrow I’ll try to get the PCI Tools mod going too.
I’ve never used Automator before. So that may be a stumbling block. I don’t think I’ve ever even clicked on it once. I assume it creates a startup file something like an autoexec.bat ?

Thanks for sharing your results. Amorphous disk mark (web) and Aja system test light (App Store) will achieve higher results.
A package arrived from SINTECH that we’ve discussed multiple times. The m.2 m-key to Apple pci ssd with fpc. My ssubx is at the office until Monday so I’ll be limited to testing an ancient x2 apple ssuax.
AjA give me the EXACT same as BM Disk Speed Test.
Amorphous showed better numbers.
[doublepost=1533942286][/doublepost]
That looks kinda FrankinMac'ish. I'm interested in the results, but probably wouldn't want that as a permanent resident in my new 1701A.
I'll likely end up selling it and getting another 970 Pro instead.

Great description. It is what it is. A lot less than 8" floppy cables
You should be able to get 229 or your ssbux .
@crjackson2134 , In a rescued 2009, I’ve installed the Sintech m.2 to apple PCIe SSD adapter in slot 4 of the ssd7101a, looping the fpc cable around the pcie slot cover. Powering up, the solution works, amber light and all, showing the ssuax in Mojave.
Heading back into the office tomorrow, I’ll be running a ssubx in the SSD7101a where I’m expecting 2000+ mb/sec from the PCIe ssd that’s usually crippled at 1500 mb/s. The fpc cable is long enough to Velcro the adapter to the bottom of a hdd tray - or - the side of the SSD7101a. Balancing the SSD on a pcie slot is not recommended.

Great, now I’ve got to order the Sintech piece so I can free up that PCIe Slot. I’m going FrankinMac for a while.
Thanks so much for posting this. Please post again when you get SSUBX results.
BTW, a little off topic, but what are those chrome rocker-switches under the SATAII connection sockets for?

yes it is me, but don't waste your time with that, it does works but is really not with it, is better to simply run raid in Mac OS journaled for now, I hope apple one day decides to add official raid support for APFS just like they did with fusion drives, I also has posted some info here in some other posts by other users but I can go later to insanely Mac and write to you there about that topic.
@handheldgames and others...
Apple dropped a completely new firmware/flasher today.
Any brave soul willing to try injecting / re-flashing with NVMe support.
Please let us know.

Passing on that thanks. My APFS and NVMe flashes to MP3,1 went fine and I believe in the old saying, "If it 'ain't broke don't fix it."
I’ll be testing the latest firmware with nvme after work.
Following up to the Sintech adapter install with the ssbux, The Apple SSD would not boot from the ssd7101a. I tried 2 times, failing in both attempts. :-/

I guess it didn't like the PLX, or possibly something is amiss with the Snitch adapter.
I just hope the latest firmware plays nice with nvme.
Yes, it works fine. My BootRom got corrupted a while back (long before this bootrom) but with the help of @tsialex it's all working perfectly.
130 boot rom works fine with the 7101A on my machine, but I'm not using a RAID configuration or hardware manipulation (PCI Tools settings). That I believe is presenting a problem at the moment. However, it's not firmware related as far as I know. I believe it's more of a tool incompatibility issue with Mojave.
