More pathethic than the write performance of WD Black PCIe is that the corrected/improved model has the exactly SAME NAME.Wow. That is one terrible SSD. Write speeds are lower than SATA. Pathetic.

Stupid question time ...For those interested in editing the microcode of their Mac Pro's system ROM, I have just finished writing a fully interactive GUI-based utility that can add/extract/replace microcodes in your system ROM dump! This is how it works:
- Open the program, and select a dumped ROM.
- From here, you can simply right-click in the table to perform actions, or use the Menu Bar items.
- To extract a microcode from your ROM, simply right-click on the microcode you wish to extract, and select "Extract Microcode". Save it to a file.
- To add a new microcode, simply right-click anywhere in the table, and select "Add Microcode". If the microcode for the same CPUID and platform ID in the microcode you're trying to add already exists in the ROM, it will replace it with the selected file. If not, it will add it.
- Microcode files can also be dragged and dropped onto the table to add them.
- Once the modifications you desire have been made, simply save the file, or do "Save as" to save it as a different file, keeping your original unmodified.
Download the application here. Source code is available on my GitHub. Microcode files can be obtained here.
Enjoy!
Quick Update on the ****** WD Black NVMe. Can confirm. The drive isn't worth its price..
Here're the results with a Samsung Evo 970.
bookemdanoHappy to report the 3rd gen WD Black has resolved whatever was hamstringing the 2nd gen. I just got the 500GB model--my first NVMe drive, and put it in a Lycom DT-120.
I was interested to see TRIM was enabled by default. I had thought only happened with Apple-badged SSDs like the SSUBX, but maybe it applies to all PCIe SSDs? Does anyone know for sure?

What is the model number of your WD Black blade?
What I'm after is how to discern 3rd. gen from 2nd. gen models.
Thanks
No problem. Can anyone else report if their third-party (non-Apple) blade SSD had TRIM enabled by default? I am 100% positive I never ran trimforce.
Hmm, I don't think this used to be the case, because I found posts where people mentioned having to enable TRIM on blade SSDs (and manually TRIM using first aid, etc.)
And now h982670 says it's enabled by default even on a 2.5" SATA SSD.
So I wonder if it's new behavior with High Sierra? Or even a later point release of HS? If others have data points, please post them (which SSD and which version of MacOS). I have some other SATA SSDs I will test (also a Crucial MX500 still in the box I can try).
My Samsung EVO 960 PRO came with the trim enabled.

Thanks but which is it? EVO or PRO? Blade or 2.5" SATA? And you're on High Sierra according to your sig, is that right?
I've followed this thread with much interest but am struggling on one question... after updating the ROM to enable NVME booting, is it possible to boot via bootcamp?
Not sure if it's related. But my MX500 (2.5" SSD) also has TRIM activated by default on a clean installed 10.13.6 on my Hackintosh.
I don't think that theory is correct (unless h9826790 has a different Crucial MX500 than I do). In my case I installed the WD Black NVMe on a DT-120 and TRIM was enabled by default, but a brand-new Crucial MX500 I put in a SATA2 bay is not TRIM enabled. I am running High Sierra 10.13.6 from a 1TB spinner.
EDIT: Unless you think that blade SSDs aren't affected by that rule. I guess I could pull the spinner and try a fresh install onto the MX500 and see if TRIM gets enabled there.
Trim is system wide. If it's enabled on one SSD it's enabled on all unless it's an unsupported function on that drive.
Also, for instance... I have a genuine Apple SSUBX in my system. Trim is enabled by default on all macOS versions (that I've used it with) on this machine when it's the boot drive.
Since it enables Trim on this SSD by default, all other SSD's are also enabled.
Further, if you upgraded from an earlier macOS version, whereby you had to force Trim, It will stay enabled in future updates.
All that being said, Mojave didn't enable Trim on ANY of my SSD's until I made do so. I think that's because I installed it on spinning rust instead of SSD.
So, I believe the key is that the boot OS needs to be on SSD for the install to automatically enable from scratch.

My Samsung M.2 960 EVO 250gb AND my SanDisk Z410 2.5" SATA SSD ( SD8SBBU240G1122 ) both have Trim auto enabled.
