Review on 💾 Seagate Backup Plus Slim 1TB External Portable HDD – Light Blue USB 3.0 for PC, Laptop, and Mac | 1-Year Mylio Create, 2-Month Adobe CC Photography | STHN1000402 by Mike Weaver

I wanted to store multiple MKV video files, each around 1GB. I got transfer speeds of 6-12 MB/s when copying files. It didn't matter if I was copying multiple files or doing a single file transfer. The disc has good reviews and is often described as very fast. I almost got it back. I tested the drive with HDTune and the speed ranges from 128MB/s to 90MB/s. Normal good performance. I did some research and did everything that was suggested including reformatting to NTFS (it was formatted as exFAT). I also enabled write caching, which requires you to use the Safely Remove Hardware process. The writing speed of a single file reached 150-160 MB/s, although in the end it sometimes slowed down to 40-50 MB/s. You must select "Best Performance" under the Policies tab for USB device properties in Device Manager.
