 Are there any differences?

They have the same hard disk inside but that doesn’t mean that there are no differences at all.

Take a look at the circuit boards in the drive case:


The top board is from the Seagate Expansion, the bottom board is from the Seagate Backup Plus.

The other differences you can read about on the box, so I won’t bore you with the details! Seagate backup plus is partitioned into two separate partitions, one comes with some backup software called Lyve which you probably don’t need. The Seagate backup also plus comes with a two year subscription to one drive which is an online cloud storage account which you probably don’t need either.


The Seagate Backup Plus and the Seagate expansion are exactly the same hard drive put into a different case.

Go for whichever is the cheapest.

Unless you live in the USA, in which case you may wish to weigh up the 1 year vs 3 year warranty.

    Seagate states that the Newer model Expansion portable and Expansion desktop drives are compatible with Windows image backup.

    Windows Image Backup in Windows 7 will not support any Seagate Backup Plus drives, GoFlex drives that exceed 2.1TB (3TB and 4TB models), or older model Expansion Portable and Desktop drives (along with most other external drives that exceed 2.1TB in size).

      Those Seagate drives that you have mentioned all work on Macintosh computers. The 2 drives I have mentioned in this article (Expansion and Backup Plus) are exactly the same in every way. Thanks for the feedback. It’s something for Windows users to be aware of.

      That’s not really true, Seagate only means “support” in the most simple of terms meaning “will you not have to do anything more”.

      You can in fact use them, if you merely put a 2TB partition on there and format to 512K block size. It’s just the factory formatting that differs with their older models having 4K blocks.

    Hello! Can you tell me what HDD is inside? does it is ST2000LM015? I want to upgrade my laptop HDD. Seagate external hard Drives are cheaper than 2.5″ HDDs like barracuda in amazon. if inside of a Seagate Expansion is a barracuda HDD, I simply can buy it and then i have a free Enclosure. what’s your opinion? Thanks!

    • Wayne says:

      Yes this is a good option. The hard drive in the photo is the one from the external drive and if you can get it cheaper than an internal drive definitely go for it. It is exactly the same drive.

    I have also done the same mistake while getting the hard drives. I got confused between both of the versions of Seagate HDDs. But after buying I verified it through that both of them are the same with just different names and packaging.
