8TB of storage space at $150 sounded more like an excellent deal, maybe one of the highest value HDD you can get today especially if you want to store a lot of games, videos, project files, etc. This HDD has slower read/write compared to other HDD at same capacity but that's not a big deal for 8TB HDD at that price. [Jun '20 ColdSpy]
