During heavy use, I'd always see read speeds drop all the way down to like 300MB/s. Write speeds weren't affected as much, which was weird.
I tried using it in an external enclosure, and it would start out fast but then go back down to those low speeds. The enclosure would also get too hot to touch, so much hotter than the 40C or so it would report.
I now have an SSD cooler from Thermalright that has a heat pipe, and that seems to keep it from throttling.
I was curious about your claims so I decided to investigate with a K Type Thermometer that I've had sitting on the shelf for awhile.
At idle the controller measured 48c with the drive temp measuring 64c so it's defiantly running hotter than the temp sensor is reporting. My drive is located on the back side of my ITX gaming PC with open panel and drive exposed no heatsink with 20GB unallocated for overprovisioning. Note I had not removed the sticker from the drive and the probe is attached to the drive with heat tape.
Performing a busy test I attempted to copy my steam library to and from the same drive (just different locations). The busy controller peaked at 80c while the drive temp was 83c.
For a large file test I copied approx. 50GB single file from my 980 pro 2TB to the TeamGroup MP34 4TB.
The controller peaked at 78c while the drive temp was 80c. The file transfer settled to 1.30 GB/s at this temperature as reported by Windows file copy.
Verdict. Yes it seems to run hotter than software is reporting. In particular the onboard sensor seems to be biased to reading nand temperature not controller temperature.
Addendum #1
I changed the position of the temp probe from the controller to the furthest nand chip and the temp of the nand is much closer to the controller reading at idle (49c/42c).
Redoing the test with the 50GB file the nand peaked at 64c while the temp measured 53c.
The file transfer this time and settled at 1.6GB/s.
Addendum #2
I changed the position of the temp probe from the outer most nand chip to the inner nand chip and the temp of the nand is even closer to the controller reading at idle (50c/48c).
Redoing the test with the 50GB file the nand peaked at 58c while the temp measured 53c.
The file transfer this time and settled at 1.33GB/s.

Copying the 50GB tests back to my 980 Pro 2TB would throttle down between 600MB/s to 900MB/s depending on the copy (multiple runs). So that's interesting there seems to be a consistency issue there.
you got a 4tb nvme for 155? seriously? damn wish i had saw that deal, thats nuts
Yea I regret not buying two at the time when it was more affordable. 8TB in raid zero for my workstation would have been really cost effective.
