Review on External Hard Drive Portable Hard Drive External Slim HDD USB 3 Data Storage by Unm Weil

First of all, it's not a hard drive, it's a USB stick, but it's 1000 GB. This is very unreliable. The file transfer speed was very strange and it goes up and down even though the file was very large. Most files are not copied. I included some image files that were error free but did not get copied to this flash drive. After copying some files it stopped responding and I lost my files. It wasn't recognized by Windows, I'm lucky I don't rely on it and I had a copy of my files on my old laptop.
