Review on WD_Black Drive Portable External Compatible by Committed Schmidt

The drive is very fast, running at speeds of up to 1500MB/s when connected to a 20Gbps USB 3.2x2 port and up to 800MB/s when connected to a 10Gb/s s-USB-C 3.2 connector /3.1 port. However, if you plug your drive into a USB-A port, you're out of luck. Even with a USB-A 3.2/3.1 10Gb/s connector, the drive only delivers around 50MB/s (in line with product reviews on various technical websites), making it inferior to some flash drives. This is likely due to a poor quality WD USB-C to USB-A cable. The rest of the memory is excellent. Small and light, runs a little hot, but manageable and fast. Bottom line: You should only use the USB-A cable as a compatibility backup on older devices (like your colleague's old desktop). If your PC only has USB-A or 5Gb/s USB-C ports, other products from Samsung, SanDisk, etc. will do much better.
