Crucial X9 1 TB, a drop height and a generation left unfinished review
A one-terabyte portable drive that publishes a drop height and a single reading figure, names a lead without measuring it, and stops its interface designation one word short of a generation.
The bottom line A published drop height, a named set of backup arrangements and one rate, on a page with no box list and no generation. The mechanical side is specified better than the electrical one, which is unusual on this shelf and still leaves the link unread.
On the listing
A one-terabyte external solid-state drive on USB-C 3.2, quoted at up to 1050MB/s and offered for computers, Mac machines and games consoles; expanded storage instead of a monthly cloud fee, with reading of up to 1050MB/s said to load files up to seven and a half times faster than a portable spinning drive and a hundred times faster than a flash stick; connection by a lead of the same connector shape for computers, tablets, consoles and telephones; a body described as shock, vibration and drop resistant from up to 2 m and able to withstand temperature swings; capacities of up to 4 TB across the range, working with the file history arrangements of both common operating systems and with a named imaging application; and three months of a photograph service and one month of a document application included with registration.
A generation left off
USB-C 3.2, and no more. Two generations sit inside that name and they are not close: one carries roughly half of what the drive quotes, the other comfortably more. Which one this drive negotiates decides whether the figure in the title is reachable at all on a given laptop. The page names the family, the shape and the rate, and omits the one word that ties them together.
Two metres, published
The third bullet gives a drop height, which is a specification: a defined test from a defined distance. Most rivals here describe a shell instead. It says nothing about ingress, which is a separate scale with its own code, and this page carries no code. As a single mechanical figure it is the most useful line on the page.
Backing up, without a writing figure
The drive is sold on holding copies of things, and holding a copy means writing. One figure is published, for reading. A large backup writes for a long time, slows once the fast region inside is full, and this page gives neither the opening rate for that direction nor what it settles to.
A lead named and never counted
The second bullet says the drive connects by a lead of the symmetrical shape. There is no box list, so it is not clear whether that lead is supplied, how long it is or what plug sits at its far end. On a portable drive the lead is part of the chain that decides the result, and here it is mentioned rather than specified.
Before ordering
Ask which generation the drive negotiates and what is in the box. The drop height and the software arrangements are the specified parts of this page; the connection is not.

Where it holds up, and where it stops
Strengths
A drop height is published in metres, which is a specification rather than a claim of toughness
The backup arrangements it works with are named individually, including the ones built into the two common operating systems
The reading figure is compared against both portable spinning drives and flash sticks, which are the two things a buyer is actually choosing between
Compromises
The interface designation stops before the generation, and the two generations of that family are far apart
No writing figure, on a drive sold for backing things up, which is writing
No box list at all, so the lead is named and never counted, measured or given a far end
Specifications
Capacity
1 TB — printed twice in the title, in the maker’s unit and reported here in that unit. The fourth bullet separately names capacities of up to 4 TB across the range
Interface standard
USB-C 3.2 — printed in the title, which gives the connector shape and the family and stops before the generation. Gen 1 and Gen 2 of that family are far apart in what they carry, and neither is named here
Stated link rate
Not published on the listing — no figure in gigabits per second appears in the title or in the five bullets
Connector type
The symmetrical connector — printed in the title and named again in the second bullet, which describes the drive connecting by a lead of that shape
Stated sequential read figure
Up to 1050 MB/s — printed in the title and repeated in the first bullet, where it sits beside multiples against portable spinning drives and flash sticks
Stated sequential write figure
Not published on the listing — the first bullet names storing games, photographs, video and files beside the reading figure, and no rate for writing appears anywhere
Stated ingress or drop rating
Drop resistance from up to 2 m — stated in the third bullet, alongside resistance to shock, vibration and temperature swings. No ingress code appears beside it
Dimensions
Not published on the listing — no measurement appears; the third bullet describes the drive as robust and reliable and gives no figure
Weight
Not published on the listing — no figure in grams appears in the title or in the five bullets
Cable supplied
A lead of the symmetrical shape is named in the second bullet as the way the drive connects. No box list appears anywhere on the page, so neither the length of that lead nor the plug at its far end is stated
TBW rating
Not published on the listing — no total in terabytes written appears anywhere
Stated MTBF
Not published on the listing — no figure in hours appears in the title or in the five bullets
Warranty length
Not published on the listing — no term of any length appears, on a page whose fifth bullet gives the lengths of two software trials in months

The questions that come up before an order
What does a drop height of two metres describe?
A test the maker specifies: the drive is dropped from that height under defined conditions and is expected to survive. It is not a promise about any particular fall, because the surface, the angle and whether the drive was writing at the time all change the outcome. It is still a real specification, and it can be compared directly against another drive quoting the same kind of figure.
Why is the missing generation worse on a portable drive than on an internal one?
Because the link is the whole product. An internal drive sits in a slot whose generation is printed in a board manual; a portable drive is reached through whichever socket a laptop happens to have, and the same connector shape spans generations that differ several times over in what they carry. Naming the family without the generation leaves the buyer unable to work out which of their own machines reaches the figure on the box.
1 TB · USB 3.2 Gen 1×1 · up to 500 MB/s as a transfer rate · two leads in the box · rubberised surface, no rating · no dimensions, no weight · no TBW, no MTBF, no warranty
A one-terabyte portable drive that counts two supplied leads and names the interface generation, and that never states the socket on the drive, a rate in gigabits or a single endurance quantity.
Best for: A household backup that moves between a computer and a console, where two supplied leads and a stated interface matter more than a full sheet of figures.
2 TB · USB 3.2 Gen 2 · up to 1050 MB/s read · up to 1000 MB/s write · magnetic case and ring supplied · two leads in the box · encryption at 256 bits · no dimensions, no weight · no TBW, no MTBF, no warranty
A two-terabyte portable drive supplied with a magnetic case and ring, whose first bullet states outright what the magnets will not do, and whose page publishes both rates and no endurance quantity.
Best for: A recent telephone used for filming, where the magnetic case is the point and the drive will spend its life attached rather than in a bag.
1 TB · USB 3.2 Gen 2 · up to 1050 MB/s read · up to 1000 MB/s write · drop resistance to 2 m · aluminium case · two leads in the box · encryption at 256 bits · no TBW, no MTBF, no warranty
A one-terabyte portable drive that publishes both sequential figures, a drop height, an aluminium case and two supplied leads, and that carries seven footnote marks whose notes appear nowhere on the page.
Best for: A laptop that travels, where a stated generation, two leads and a published drop height matter and the drive will be carried loose.
