    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.

    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.

    Shucked the drive so I don’t use the external case, but otherwise it’s a good drive, I have it in a NAS but not sure how well it will do 24/7 I’ll update this when I know more

    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.

    Decent price (high) for external storage however I had issues adding to my NAS as a backup device (could be an issue with USB 3.0 but I am unsure at this time). Still usable.

    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 .

    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.

    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.
