Review on UnionSine 500GB Ultra Slim Portable External Hard Drive USB3.0 HDD Storage - Ideal for PC, Desktop, Laptop, Xbox One, PS4 (Black) by Joe Roberts

I give this drive 2 stars because it did what it was supposed to do in the 60 days it actually worked. One day I booted up my computer and tried to access files on this external hard drive. Drive and drive letter changed to something else and it always said "Invalid directory name". I couldn't restore the previous version nor fix the error - everything I had stored on it was completely erased (my fault for not backing up my files to the cloud) and became unusable. Based on my experience, I do not recommend this drive and warn others to back up their files if this happens to you.
