Seagate 4 TB portable drive, with two of five bullets about where to buy it review
A four-terabyte portable drive whose page names a generation, a compatibility list and a marketplace exclusivity twice, and that never states a connector, a measurement or a warranty.
The bottom line Four terabytes, a stated generation and a useful compatibility list, wrapped in a page that spends two of its five bullets on where the drive may be purchased. The interface half of the specification never arrives.
On the listing
A four-terabyte portable external drive on USB 3.0; sold exclusively through one marketplace; expanding a computer’s capacity with a light, compact solution compatible with computers, notebooks, Xbox and PlayStation 4 consoles; immediate plug-and-play compatibility with simple drag and drop; fast file transfer over USB 3.0, backwards compatible with USB 2.0; and a closing instruction to buy the product exclusively at that marketplace.
Two bullets about the shop
The first and the fifth say the same thing: this drive is sold in one place. Neither describes the drive. On a five-bullet listing that is forty per cent of the space, and the lines it displaces are the ones that would have named a cable, a connector or a measurement.
Machines, not operating systems
Computers, notebooks, and two console families named outright. Most compatibility lists on this shelf give operating systems, which tells a buyer less than naming the console in the living room does. This is the most useful line on the page, and it is specific enough to act on.
Backwards, and forwards
The fourth bullet states that the drive works on the older USB generation as well as the one in the title. That is the difference between a slow copy and no copy on an older machine, and stating it is worth more than the adjective fast that sits beside it.
What plugs in
No connector, no cable, no box list, no word on power. The generation is named twice and what carries it is named never, which on a portable drive is the practical half of the question.
Before ordering
Ask what is in the box and which plug the cable carries. A console owner in particular should confirm the socket before the drive arrives rather than after.

Where it holds up, and where it stops
Strengths
The compatibility list is specific about machines rather than operating systems, naming computers, notebooks and two console families
Backwards compatibility with the older USB generation is stated rather than assumed, which matters on an older machine
Four terabytes in a portable body is the joint largest portable capacity on this shelf bar one
Compromises
Two of the five bullets are about where the drive may be bought rather than what it is
No connector, no cable and no power statement, so nothing on the page says what actually plugs in
Light and compact are both used as claims and neither is given a figure
Specifications
Capacity
4 TB — printed in the title, in the maker’s unit and reported here in that unit without conversion
Portable or desktop format
Portable — the title names it a portable drive and the second bullet describes a light, compact way of expanding a computer’s capacity
USB generation
USB 3.0 — printed in the title and named again in the fourth bullet, which adds that it is backwards compatible with USB 2.0
Stated link rate
Not published on the listing — the fourth bullet calls file transfer fast and names the generation, and no figure in gigabits per second follows it
Connector type
Not published on the listing — no socket is named on the drive and no plug is named at the computer end, on a page that does name the generation twice
Power source
Not published on the listing — no mains adapter is named and no statement about drawing power from the port appears; the third bullet promises immediate plug-and-play compatibility and nothing about supply
Stated dimensions
Not published on the listing — the second bullet calls the drive compact and prints no measurement
Weight
Not published on the listing — the second bullet calls the drive light and gives no figure in grams
Cable supplied
Not published on the listing — no lead is counted anywhere in the five bullets, and no box contents are given
Warranty length
Not published on the listing — no term of any length appears in the title or in the five bullets

The questions that come up before an order
What does backwards compatibility with an older USB generation actually give?
It means the drive works in an older socket at the older rate, rather than not working at all. On a machine whose ports predate the generation printed in the title, that is the difference between a slow copy and no copy. It is worth stating and this page states it, which several rivals here do not.
Does an exclusivity claim belong in a specification?
It describes where the product is sold, not what it does. Two of the five bullets here carry it. Neither adds a figure, a socket, a measurement or a term, and on a page with no box list and no connector that is space spent on the transaction rather than on the product.
4 TB · portable · USB-C · USB 3.2 Gen 1 and Gen 2 and Thunderbolt 3 listed · shock, water and pressure resistance claimed · three-year warranty · one cable in, one out
A four-terabyte portable drive that lists five interface standards it works with, names the cable in the box and the cable that is not, and publishes a three-year warranty.
Best for: A drive that leaves the desk and goes into a bag on a site or a shoot, where the protective claims and the published warranty are the reason to pay more.
1 TB · 2.5-inch portable · USB 3.2 Gen 1×1 · certified refurbished, reconditioned in Germany · no cable, no connector, no measurement published
A one-terabyte portable drive that names its USB generation precisely and states that the mechanism inside it has been reconditioned and fitted into a new case.
Best for: A modest second copy of documents and photographs at the lowest price on the shelf, where the reconditioned mechanism is understood and accepted in advance.
500 GB · 2.5-inch portable · USB 3.0, also working on USB 2.0 · up to 120 MB/s read and 103 MB/s write · one cable in the box · three-year warranty
A five-hundred-gigabyte portable drive that publishes read and write figures and calls them theoretical, lists what is in the box, and names neither its connector nor its measurements.
Best for: A small pocket drive for carrying documents and photographs between machines, where the modest capacity is the point and the price reflects it.
