Review on 💨 MOVESPEED Portable External SSD 512GB - USB 3.2 Type C & Type A - Ultra Dual Solid State Drives SSD - Mini SSD - Speed Up to 520MB/s - Smartphone, Mac, Windows, Android, Linux Gaming-Compatible by William Mathis

PRO AND CONS1. By the title I mean this 2 3.4 inch long device is made of metal and it looks like it's even bulletproof. Although sold as a 256GB drive, the available storage space is actually 238GB3. As a test, I copied 2 GB from my Samsung 970 EVO NVMe M.2 250 GB SSD desktop PC to MOVESPEED. Transmission time: 73 seconds. This is less than 5% of the speed stated in this product description. I then ran a second test by moving the same 2GB to a 128GB MicroSD card installed in a USB 3.0 adapter: 108 seconds (see my second photo).4. Flip-up covers for USB and microUSB 3 ports are solid metal and snap into place (extremely secure). CONCLUSION: If you want a flash drive that's designed like a tank but isn't really that much faster than a $15 256GB microSD. , buy this. I would like to know exactly how this device can run at 520MB/s in the real world.
