Review on WEme SATA to USB C Adapter for 2.5-inch SATA I II III HDD/SSD, UASP Supported – Compatible with WD, Seagate, Toshiba, MacBook, Type-C Laptops & More by Mike Bray

I used this adapter to connect an SK Hynix Gold S31 (560MB/s) SATAIII (6.0Gb/s) SSD to a Macbook Pro with a Lightning connector (10Gb/s). s) to connect. The theoretical maximum speed should be around 560 MB/s. With this adapter, I got 39MB/s reading and 33MB/s writing on CrystalDiskMark. It's starting to hurt. Conclusion: This inexpensive adapter offers terrible performance. Why connect a fast USB3 port on your computer to an adapter when it can only support USB2 speed?
