This video shows how an external SSD can overheat and go into thermal throttling. Once an SSD has hit the point of thermal throttling it will become slower.
For the test I'm using the Zike Z666 USB4 40Gb/s enclosure, which is a passive enclosure. The other enclosure is the Acasis TBU405Pro M1, which is Thunderbolt 4 USB4 and uses active cooling with a fan. Both enclosures have been tested with the same SSD, which is the Western Digital WD SN850X NVMe Gen 4 M.2 SSD and the one used is the 4TB version.
So for this test I am doing SSD disk speed testing. I test each drive with the Balckmagic Disk Speed Test app, then I do a long stress test where I write to the drive for over 50 minutes, then I perform another disk speed test.
After the testing it's clear to see that the Zike overheats but the Acasis does not.
I said in the video that I would do real-world speed testing. However, as the Zike had overheated and the Acasis clearly beat it with the synthetic speed test, it just wasn't worth doing the real world test.

https://geni.us/Y7TFRMy recommendation for a fast Thunderbolt 4 USB4 external SSD for your Apple Silicon M1 M2 M3 or M4 Mac is the Acasis TBU405Pro M1 enclosure, paired up with the WD SN850X SSD. I use the 4TB version and it's awesome. This combination does not thermal throttle as the Acasis enclosure is fan cooled and keeps the WD SN850X below its thermal throttling point.

https://geni.us/SN850X-1TBWhile I obviously have thermal issues with the Zike Z666, it will work with many SSDs without overheating and going into thermal throttling. However, as of yet I do not have any recommendations for an SSD with the Zike. If you decide to buy the Zike Z666 you can get 20% off on the Zike website using my promo code "David20".

https://amzn.to/4g478G4I have not thoroughly tested the 990 Pro with all of my enclosures. However, this is an excellent SSD if used internally with a computer with proper SSD cooling and good airflow. While I can't recommend the 990 Pro just yet for any use with any enclosure, here's some links for anyone who is going to use it in a properly cooled computer.
