    I've bought a number of Seagate Expansion drives. They've worked well out of the box, are easy to format and make minimal noise. Very happy

    It does what it's supposed to. I have 17 terabytes of movies and TV shows and it all fits here. Now I can put bigger drives in my NAS and have everything safe on the expansion drive.

    First one I got was DOA. Second one is very slow to get recognized by windows. Once it does, its fine. Copy speeds are very slow as well. I knew it was going to be a slow drive, but it's for backup storage so not a big deal on speed after I finally get everything over. No noise complaints.

    Normally I purchase WD products, but this time I decided to give Seagate a try... It powered up without any issues, no signs of any failures, and surprisingly was pretty quiet compared to my other hard drives...

    Solid performance. Good but not world beating at anything but total storage for the price. If you need to store large amounts of data with good performance and reliability, it’s hard to beat this drive.

    It does everything I expect from a hard drive. Although I purchased this on sale, I deducted 1 star due to the price.
