Customers are saying

Customers recognize the Expansion 20TB External Hard Drive for its substantial storage capacity and satisfactory overall performance. While some appreciate its pre-formatted ExFAT for broad compatibility, others have concerns about the drive's write speeds and connectivity limitations. The noise level is acceptable for most users.

    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...

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

    I was using this as a backup for my NAS and it's already being a pain. Said it was not safely ejected and went read only even though I never touched it. Case feels like it's made out of the same plastic as a Ring Pop. Regardless of what drive is in it there's no point in spending money on this when you can get manufacturer recertified enterprise drives for less with a better warranty. Side note: love how the box uses an entire panel to advertise that the US gets the shaft on warranty when every other region gets two or three years. Very cool, Seagate. Thank you. Way to stand behind your product by doing the minimum the law will allow.

    It works quite well, you can plug it in and it will start running shortly. This is actually an 18 TB drive, not 20. Convert from exFAT to NTFS immediately. May hang and have delays. It functions as a large archive. It isn’t super fast as a result of its immense storage size.

    While spacious, it's an SMR drive and does not disclose this on the packaging. Read speeds are fine, but write speeds are under 40MB/s, which largely defeats the purpose of a drive this large. Recommended *only* if you know what you're getting into.
