Review on ORICO M.2 NVMe SSD Enclosure: High-Speed USB 3.1 Gen 2 (10 Gbps) to NVMe PCI-E SSD Case - Supports UASP, NVMe SSD Size 2230/2242/2260/2280 (Up to 2TB) by Bill Tripi

This is a well built case and I would love it. However, I have an M1 based Mac and this product does not work well with M1 based Mac USB controllers. The information below only applies if you have an M1-based Mac. I bought this ICY BOX case (IB-1817M-C31) for M .2 NVMe SSD. I have an NVMe SSD: Sabrent 2TB Rocket NVMe PCIe M.2 2280 Internal High Performance SSD (SB-ROCKET-2TB)) This ICY BOX uses the JMicron chipset (JMF583). Unfortunately, this chipset doesn't work well with M1-based MacBooks. What I saw was around 550MB/s write/read when the SSD is unencrypted. And 100MB/s write/read with an encrypted SSD. I then searched the web and found that others were having similar issues with this JMicron chipset and M1 Macs. However, they reported that cases based on the Realtek Semi RTL9210--VB chip performed much better. So I ordered this ORICO enclosure: ORICO M.2 NVMe SSD Enclosure, USB 3.1 Gen 2 (10Gbps) to NVMe PCI-E M.2. SSD enclosure UASP support for NVMe SSD size 2230/2242/2260/2280 (up to 2TB) With the ORICO enclosure, I have read/write speeds of 850MB/s with a NON-encrypted drive. And 760 MB/s writing and 710 MB/s reading with encrypted hard drive. Even with the new ORICO case, the performance/speed is slower than it could be as Mac M1s have a common problem with external USB drives. I will eventually order a Thunderbolt document (which uses its own USB controller) that will solve this problem, and then I expect write/read speeds of >900MB/s. Summary. I am NOT saying there is anything necessarily wrong with the ICY BOX case. (actually I liked the construction and design). My search shows that there are many happy customers (and YouTube videos/reviews) showing it can run at advertised speeds. The problem is that the controller (JMicron) doesn't work properly with M1 based Macs (Apple Silicon). So if you have an M1-based Mac, you should stay away from this controller. I know Realtek works. I did all these comparisons with the same disk (moved them between cases).
