Customer Reviews

Seagate Expansion USB 3.0 Portable External Hard Drive - 4TB (Black) is rated 4.9 out of 5 by 46.
Rated 5 out of 5 by from Peace of mind at an affordable price Neat and compact yet holds 4 times more than my previous portable HD. Very good value too. Provides peace of mind as it makes back up and security of my data easy and at a very affordable cost. Cloud storage can work too but there is still a part of me that likes the idea of retaining access of my own data and this product allows this and also lets me manage the way data is filed for future access if needed.

Rated 1 out of 5 by from Good for the price I don’t know what the transfer rate is, but it takes a long time to copy and to load up lists of files in my finder/file manager. So reviewing files is agonizing. So I’m just using it as storage for now and I have to use some of my old hard disks instead, because they don’t stagger when I’m scrolling through files for sorting. That’s the disappointment for this product.
