    This hard drive works great for saving my games. I had some trouble with it at first, but the Geek Squad fixed it for me.

    If you need an external hard drive, this is the one for all those pictures you have all over your computer. Plenty of room for more projects too.

    Loud in Enclosure, Shuckable, Value on Sale

    The drive is noisy A lot of drives are, but this is more about enclosure dampening of sound It has rubber feet for standing up, but it’s 2x louder standing (if not more) If you put it on a desk that is a typical ikea cheaper wood design, it will thrum, clunk and echo that sound under the desk, amplifying it Laying it flat lessens the noise, and putting some foam pads under it helps Some people buy these on sale to shuck for cheaper storage They are good for that and probably better than using the included enclosure sound wise Overall good drive, minus 2 stars for very bad (loud) enclosure design. Especially since these are more consumer marketed

    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.

    For me an "excellent" product is a product that lasts. Longevity is the main reason for a product like this. Only time will tell. Seagates smaller external drives seem the sturdiest built, but this big guy seems a little bit cheap. Interesting that it came with ac adapters for every region .

    I’ve been using this external hard drive for a few months, and it’s been excellent. The setup was quick—just plug it in, and it’s ready to go. Transfer speeds are fast and consistent, even with large files, and it runs quietly without overheating. The build quality feels sturdy, making it great for travel or regular daily use.

    Constantly sounds like its shuffling through a deck of cards. Maybe 2-3 times an hour. Initial reads can take some time . I thiught my last hard drive was wearing iut due to this behavior but this new one does it too.

    Decent for archival purposes, fast enough, but gets disconnected from time to time from my Mac computers compared to my equivalent WD drives (I know they're the same company). Wouldn't buy again, but still useful for my purposes.

    i was running low on my tree m.2 4TB SSD's but man this HDD saved me on storage but be aware your PC will take away 2TB of space from the 20TB drive for backups and the drive will say 18.1TB not and 20TB but over all seagate never fails me.

    With the ever growing file size of digital photos, this is fantastic for backing up all of these large files. I've been using Seagate hard drives for many years.
