If I would like to use just that Star point Adapter card- how should I cool the drive in that scenario?
Ops, I answered thinking that you want the Startech PEX4SFF8643 model that just has the U2 connector and not the drive on the same PCB. Velociraptor heatsink won't work for this scenario.

You need to cool just the drive, not the adapter.

Best, and really cost-effective, way is to buy a WD Velociraptor 1st generation and use just the heatsink with 1,5 and 0,5mm silicone thermal pads between the drive and the heatsink.

Eventually you can find the 300GB WD Velociraptor for less than $35 on eBay, but takes some searching. I was looking for another Velociraptor heatsink, created email searches and nothing showed for a decent price in months then @ZombiePhysicist asked me how I was cooling the Micron drive and I found one for him at the same day with a killing price - lucky guy.

Now I’m confused ;)
If I wanted to use the Micron 9300pro with the aforementioned starpoint adapter Card- what’s the best recommendation for cooling the drive?

I don't recommend that solution for the Micron 9300Pro drive, it's a very hot drive when in heavy use and the drive itself is heavy. The PEX4SFF8639 adapter don't even have a PCIe lock.

If you have a Promise 2Ji with one empty bay, buy the Velociraptor heatsink, the SFF-8643 to SFF-8639 cable and the Startech PEX4SFF8643. It's the best way to install the drive.

I see, hm well I don’t have a promise 2Ji... ok maybe I’ll just stick with the sonnet 4x4 ;)
 
I tried the above mentioned Startech card with an Intel P4600 6.4TB u.2 nvme SSD and got nothing but an Unknown NVME drive in system profile.

Great deal on those P4600 if I can get them to work.
 
I am trying to use the Startech adapter with an Intel P4600 U.2 Drive and can't get it to be recognized. Gonna try to install it in a modern PC and see if it is recognized.

I dont think all U2 drives and controllers will work. The Shnazzy Youtube guy tried another another U2 drive and controller and also didn't work.

It's not clear to me if it's the controller or the drive or both that keep things from working. And while I definitely would listen to @tsialex sage advice, if I were doing this again from scratch, I would try that StarTech adapter with just the Micron drive (having the backup plan of getting the highpoint card if it doesn't work).

I think there are screw points to screw in the u.2 drive so the weight of the drive shouldn't be a factor. I also think if you put the card and drive lower in the slot range you might get better air flow over it than in the J2i cage. It won't hurt the drive to try and run it right off the card to just see what the temperatures are. If they are in the 130s or lower, I think you're fine. Also, I might try putting a few thermal pads and NVMe fin heat sinks on it, and I bet that would bring temperatures down a fair bit too. It's worth a shot. The Startech card isn't that pricey. And if it doesn't work, you can just go the route that I did.

As always, YMMV.

Any luck getting the Intel U.2 drive to show up in Catalina? So far it looks like Micron drives work and was hoping Intel's were working too.

Heavily considering getting one of these for production scratch drive. Have you run into any problems or has it been smooth sailing?

Knock wood. No issues with my specific setup here.


Been my main drive all this time.
 
HighPoint SSD7101A-1 PCB revision 2.00 uses a PWM fan with variable rotation that have a lot less fan noise than my v1.01. You can always replace the fan for a less noisier model and install improved heatsinks if you are in a studio and fan noise makes you crazy. People here have parts list already to mod it.
How can you tell which PCB rev you have? My board says V2.00 in the lower left by the screw.

I searched the forum but couldn't find the thread/posts about fan upgrades for the SSD7101-A. Could you (or someone else) link to it?

Bonus: does anyone know the style of pins/connectors on the fan of the SSD7101-A's PCB?

This is the post about the fan mods:

Btw, PCB v2.00 with the last firmware can shutdown the fan via web interface. If your card don't have the last firmware, you can get in contact to HighPoint for a firmware upgrade. They will ask you to send the card for the upgrade process, it's done in their labs.

So one thing I cannot tell is if this drive has TRIM support. I suspect it does, but how do I tell if a) it does, and b) if it's enabled?

SystemProfiler.app under storage shows the Medium Type: SSD. I could swear it used to have an entry for TRIM yes/no? But looks like they took that out of system profiler as it doesn't even show it for the apple SSD.

Does anyone know how to tell if the drive supports trim and how to tell if its enabled or not? This is obviously under the latest version of Catalina. 10.15.2

Thanks!

So the info is in system profiler if you have TRIM support, but it's not in the storage tab. It's in the NVMExpress tab. What is interesting is that the built in garbage apple 256SSD does have trim support on by default (not surprising), but the Micron has TRIM support enabled by default (which is surprising as I thought no 3rd party drives get TRIM support by default).
 
I take a "garbage" NAND module made from SLC and MLC NAND over any TLC/QLC SSD any day. :p

It's extremely rare to see failed NAND modules from iMac Pro, seems Mac Pro modules are the same.

While that is technically true, I see more horror stories about lost data with T2 drives, out of the control of the owners, than I'm comfortable in trusting. And it's not the SLC/MLC part of the memory I have a problem with (which I agree is preferable to the TLC/QLC--at least when all other things are equal), it's the T2 overlording that memory. I'd personally feel more secure and rather take my chances with chad riddled punched paper tape over Apple's T2 garbage.

Obviously fair minded folks can differ on the merits (and problems) with the T2. But for my purposes, it is garbage. Obviously YMMV.

So I just picked up my second MP 7,1 that will serve as a video editing workstation. I ordered a new HP 7101A-1 card and of course now it has the updated firmware. A few things I've noticed: The fans at medium speed are just barely detectable to my ear, but not enough to care. High speed is an annoying whine, like a mosquito. At medium speed the 2TB 970 EVO Plus cards I have are running about 37C when the machine sits idle for a while, about 43C when under normal use. I copied 6TB of data to the array and that caused the temp to spike up to 62C. Even putting the fan on high made no difference there, so I used a fan control app to rev up the MP fans and that nicely cooled them down.

Now my thoughts: I did the fan replacement on my other card using the DigiKey fan. That fan actually is a tiny bit quieter than the one from HighPoint when it's in "Medium" speed mode, and also keeps the card about 2-3C cooler on average. Now I'm debating getting the 3-pin version of that fan from DigiKey and replacing the one my new card, just to get rid of the very faint noise. Has anyone tried that yet? If so, does the speed control all work fine (it should)?
 
Here is a new card:


My guess is you cannot boot the RAIDed sticks so you need one stick to boot and can RAID the others... nice that it's fanless though.

With a x8 card, so it's probably using an entry level PCIe switch. It's a competitor of OWC card not a SSD7101A-1 replacement, weird that HighPoint went this way. Has two versions, SSD7202 for two blades/half height and SSD7204 for four blades/full height:



Btw, both cards don't support arrays that span between two cards, what HighPoint calls cross-sync.

Running macOS Catalina version 10.15.6 via on a Micron 9300 MAX 6.4TB U.2 SSD;
  1. On my iMac (Retina 5K, 27-inch, 2017) 3.4 GHz Quad-Core Intel Core i5, via:
  2. Highpoint RocketStor 6661A Thunderbolt 3 to PCIe 3.0 X16 Expansion Chassis;
  3. StarTech.com U.2 to PCIe Adapter - x4 PCIe - For 2.5" U.2 NVMe SSD - SFF-8639 PCIe Adapter - U.2 SSD - PCIe SSD - U.2 drive (PEX4SFF8639).
  • Had to disable System Integrity Protection via Terminal (csrutil disable)
  • Installed Catalina from booting in Command-R (internet download)
    • Had a few hiccups during the install where drive did not remount after a reboot.
  • On this iMac via a TB3 connection, the drive runs at about 2400 read/write per BlackMagic Disk Speed Test
  • Runs hot with constant use but the speed on the Micron 9300 MAX 6.4TB U.2 SSD remains stable.
My 1TB Fusion drive sucked, having been storing my libraries on slow external HDDs for years. Don't need a newer iMac and cannot justify the many thousands extra I would spend to get 4TB or 8TB of SSD internal storage.

Wanted everything on one volume. Played around with logical volumes, RAID volumes, combinations of M.2 NVME SSDs, and decided against keeping single 8TB QLC M.2 NVME drive.

The Micron Max is not the least expensive option (noting I probably should have gone with the Micron 9300 Pro series) but the dollars per terabyte don't seem too bad when you consider its rated endurance at 37.3PB written--arguably more reliable than the best M.2 like Samsung 970 Pro and substantially less expensive per terabyte, and the Samsung 970 Pro tops out at 1TB.

Sonnet unveiled a new u.2 NVME card that can hold 2 u.2 drives on the card. No fan.


You can RAID 0 but you cannot boot the raid drive unfortunately... Interesting and tidy solution. It wastes a 16lane slot to some degree in that you are feeding only 2 drives 4 lanes each, so the other 8 lanes are essentially wasted. The high point solution gives you access to all 16 lanes, albeit via 4 drives.
