Acasis site has good Black Friday prices AND an additional 15% to 20% off of already discounted prices.
I went for 3 x TBU405 Air (Thunderbolt 3/4 and USB 4.0 but not backwards compatible with older USB interfaces). On sale for $59.90, less than $50 each with the discount applied.
Combine with 1 TB NVMe and it's only slightly more expensive than a 1 TB thumb drive, but 5x faster.
I have already bought the second for around 50 inkl. shipping and Tax.
The Upside is you can use it as a Boot Drive and then it also stays 10 Degree colder.
So the Test for me with a WD SN770 has showed 42 Celsius as non Boot drive and 32 Celsius average as Boot drive.
iStat also shows a continuous 4 Watt drain from the Drive when used as non Boot Drive.
There seems to be a basic Problem with MacOS handling external Drives.
I disconnect them all because of that and they are only Backups anyway.
Is there an enclosure/NVMe setup that doesn't heat up, even if it means lower speeds ?
Some people refer to the T7 & co. alternative, but it seems to me that there are also heat-related problems with the appearance of a white wax.
I'm still stuck with my SATA enclosures, despite having updated devices (M1+M4 Pro).
PS: I don't know if my message here will go unnoticed...
See above comment about using it as Boot Drive and also with the Acasis TBU404 Air and WD SN770 NVME.
This is the first time I've heard of this drive (SK Hynix Gold P31). Looking at reviews it seems to run fast and cool and it has DRAM.
One of the big obsessions of and frustrations in this thread is how hot these TB4/USB4 enclosures run. And yet, in this thread and others, the overwhelming choice for everyone seems to be the Samsung 990 Pro or the WD BLACK SN850X. Both of these drives run much hotter and are more expensive than the SK Hynix Gold P31.
So why the preference for the Samsung and WD Black over the SK Hynix Gold (or even Platinum, for that matter)? The SK Hynix Gold runs 10ºC cooler, performs very well, and is $30-$40 cheaper (at least in Canada).
What are the drawbacks of the SK Hynix Gold P31 compared to the Samsung and WD Black?
In the context of Mac or Hackintosh i just have no experience with SK Hynix Gold P31, but used Crucial P2 and the listed WD NVME without any Problem.
My WD SN 570 / 770 / 850 are running very cool internal (i know this also from using them with Hackintosh) and external it is different and related to the Chipset of the enclosure or Host.
The Main reason seams to be MacOS because there are the Samsung NVME with Phoenix Controller if used as Boot drive taking up to 20 Minutes to Boot after a while because a Trim problem related to APFS.
The WD SN 850 runs perfect internal but will not be recognized in an 10Gbit External with the RTL9210b Chipset in my Highly Compatible Inateck FE2025 but only at my MBA M2 when connected to my Hackintosh it just runs fine.
The WD SN770 runs also at the MBA M2 in it.
In my TB3/4 Intel JHL7440 Chipset Acasis TBU405 AIR the WD SN770 runs when used as a Boot drive 10 Degree Celsius Cooler.
While it was my Plan to use as Boot Drive with a New MacMini M4 Standard anyway, i am ok with it.
Have tested it at my MBA M2.
As i am using Mac´s for Decades,
i just know that you have to check anything with everything USB related at a Mac.
