Customers often highlight the ample storage capacity of the Expansion 18TB External USB 3.0 Desktop Hard Drive, praising its ability to hold vast quantities of files and high-resolution footage. The drive's ease of use and relatively compact size are also frequently mentioned as positive aspects. However, some users note that the drive can be somewhat loud during operation.

    This is a very good external hard drive that provides a lot of storage space and is surprisingly small. The only nitpick I can give is that it can run loud sometimes, but an old spinny drive like this should just be used for backups and storage anyway, so it's not a big deal.

    For data holders, this is a very solid external hard drive. Well, it can be a little noisy when being accessed, this is a solid value play on a dollars per gigabyte metric. It may be obvious, but keep in mind that these drives need a power supply so be sure to account for that win planning your purchase.

    My work has these 10 year old Drobos that are a pain and running out of space. Attempt of upgrading the drives in size didnt help. I got 2 of the 18 TB versions and backed up the entire Drobo with a TB to spare until we get a Synology with over 200 TB. Note both drives are set up for backup incase someone knocks 1 and renders it inaccessible. Right now i have them back in their box.

    The drive has performed flawlessly and has very high data transfer speeds. Unfortunately the drive comes formatted with the exFAT file system, which isn't recognized by my online backup - so I had to reformat the drive.

    Seagate is a great brand, the last drive I bought was WD and it fell 2 feet onto carpet and got corrupted when I’ve traveled with Seagate and never had an issue
