EVERYTHING that I have been using (Apps) works so far, even running the Server App. too. Handoff/Continuity all Good. I am in the process of upgrading the WiFi to a better, 802.11ac card. The newest OCLP is a game changer with the GUI, it detects if there is a OCLP update and in general, all of the macOS updates should be seemless...but you know, something might work today, and Apple might break it in a later update. ?
It's worth noting, SOME SSD's simply do not support TRIM. Having said that, most of the mainstream Samsung SSD do/should, especially the 2.5" SATA.

So, here is the Trim article I read all those years ago.
Also, why I installed the Kingston V300 SSD (I already had on hand) in my Mac-Mini. It had a SandForce 2281 controller like the OWC drive. And finally, why I never worried about turning-on Trim (he said it wasn't necessary).
With An OWC SSD, There's No Need For TRIM
If you’ve researched using an SSD before, you may have heard how they can slow down over time. Most manufacturers avoid this by suggesting users run TRIM.

OWC might have some additional logic in their controllers, but I've never seen an article yet, where TRIM has been stated to be a bad thing, turn on only if needed, etc. etc.So, here is the Trim article I read all those years ago.

Here is a new OWC article 1.5 years later (just now reading this myself).
OWC SSDs Built to Perform with or without ‘Trimforce’ Command
On Tuesday, Apple released the latest update to OS X with version 10.10.4, which among other improvements adds the support of TRIM for third-party SSDs.
So, back then, the OWC-SSDs were using SandForce controllers:
OWC Mercury Electra 6G SSDs boast big speeds, price to match
Other World Computing may specialize in upgrading aging Macs, but you don't have to own one to jam one of its new Mercury Electra 6G SSDs in your computer. The high-end SandForce Driven line of NAND drives range in size from 120GB to a far more impressive 480GB and, with the aide of 6Gb/sec SATA...
So, this is promising because OWC is saying their (SandForce controller) SSDs can use Apples Trim functionality without problem. It's also fairly obvious that their SSDs were either very-close to Kingston drives or possibly even "rebranded drives". Notice in the Comment Section for the above OWC article. They are talking about firmware version for their OWC-SSD's but they just so happen to be the same as my Kingston V300 SSD firmware versions.
Q1. ELECTRA SSD ... from the old 506ABBF0 to the newest 603ABBF0.
Q2. is that recommended for SSDs with current revision 522ABBF0? Would that bring any performance improvement or would it be the same?
A2: If your OWC SSD Firmware revision contains xxxABBF0, then 603ABBF0 is the most up-to-date revision. It is recommended to update the firmware whenever a new one is released. This will guarantee that your SSD is running flawlessly.
You probably won't see immediate improvement in the first boot after enabling TRIM. Those deleted files before TRIM getting enabled are still oblivious to the SSD controller until their locations are replaced with new data and get deleted to make them free. Personally I would not hurry the process (by creating large files then delete them) since that will unnecessarily create wear and tear. I would just use it normally.
Yes. And I would leave at least about 20-30% space of the drive empty for optimal write performance.
Oh, great.
If you have the original install discs with your Mac Mini, there should be an AHT on there with a Memory test. Otherwise just run memtest86 if you're used to that. It works on Mac Minis.
As long as the OWC memory was rated for your make/model, it's likely fine. If you are running macOS with al of it's original partitions, you can just turn off the system totally...when power own and immediately press and hole the "D" key, until you see the status bar, you can then let go. This will either run the AHT or prompt you to connect to WiFi for the online diagnostics, depending on your installed OS. Of course, as has already been indicated, you can run memtest86 as well, I would just get the newest free version and not an ancient one. https://www.memtest86.com/
I agree about the OWC memory likely being fine (that's kinda why I bought it there). However, this procedure is just what I've always done on my WinTel machines. About 10% of the time, something is not quite right. If you don't catch it now it causes some major problems later (and yes, Memtest86 will catch it).
Keep in mind the AHT, is a very superficial test. "Hello hardware test target are you there?" "Yes I am here!" PASSED! The memory test feature is also very superficial tests sequences, memtest86 is by far more extensive and through, if that is your goal.
Oh really? I was hoping for at least a thorough RAM-Pattern-Test. Sounds like it might not be of much use after all (even for other hardware diagnostics in the future).
