In real life though, a 10GB mix of files and folders took around 74 seconds to be transferred which is roughly 137MBps which is a bit faster than the 2019 Backup plus at around 130MBps. Writes varied from 129 to 137MBps while reads hovered around 140MBps on average, depending on what software was used. There’s no real surprise in store during the test: I used five benchmarks and it was a mixed bag as there is no real innovation (other than the Type-C connector) compared to the previous external 5TB hard drives. New technologies like HAMR or Helium are reserved for more lucrative markets like data centers where the need for smaller 2.5-inch hard disk drives is non-existent.

There’s not much hardware improvement that can be made as there is little to no incentive to invest in R&D.

What I wrote four years ago is still valid large-capacity portable hard drives have reached a plateau.

Three things that are notable about this drive are (a) it is thicker than average (15mm) thanks to the extra platters it carries, (b) it is more expensive than external hard drives that use it: $129 when we last checked on Amazon (c) it has a two-year warranty whereas all Seagate external hard drives have three-year warranties by default. At the heart of all the six 5TB portable hard drives sold by Seagate is a 5TB Barracuda internal HDD, the ST5000LM000, which spins at 5400RPM and has a 128MB cache. I reviewed one from Seagate, the Backup Plus, in 2019.
