My brand new 5 Terabytes 3.0 USB Seagate Expansion Desktop external hard drive was transferring data at 15MB/s, and this is super super slow for 3.0 USB external hard drive. At first, I thought the hard drive was bad even though it is new. After tinkering with the hard drive and Windows, I finally found the solution to the problem. It was a Windows’ hard drive policy that prevented this drive from transferring data at the correct speed. After fixing up the problem, this drive is now transferring at 150 – 200 MB/s data speed. In the video right after the break, I show you how to speed up your slow external hard drive. Enjoy!!!
