Review on Transcend 4TB USB 3.1 Gen 1 StoreJet Shock Resistant Rugged Portable Purple External Hard Drive + Compact Case by Stanislaw Glusinski ᠌

I have known these wheels for a long time. The controller fully uses USB 3.0 - USB 3.0 transfer speed is limited only by the speed of the drive itself. In younger models for 500 - 1 TB, the USB-SATA III controller is made separately from the disk and you can install your own disk. often used this option as a device for connecting external drives via USB. Different pros: Inside WD Blue 5400 rpm / 128 MB, SATA III - 6 Gb/s Real read/write speed about 125 MB / sec at the beginning of the disk and about 60 MB / second at the end of the disk Good rubberized casing. The drive is fairly quiet. No additional USB power required enough regular from USB 3.0 Cons: - it's still WD BLUE (and not RED for example) - the controller (adapter) from USB to SATA III is located directly on the disk, that is, replace the native disk with some other regular one 2.5" drive or SSD won't work.
