Crucial BX500 1 TB, three years and a named encryption standard review
A one-terabyte drive that publishes a term, a named write acceleration mechanism and three encryption standards by name, and that never quantifies writing or endurance.
The bottom line A page that names its mechanisms and its standards carefully and quantifies almost nothing. The encryption line is the most specific claim in this lot; the writing side and two of the three endurance quantities are absent.
On the listing
A one-terabyte solid-state drive in the 2.5-inch format on SATA, quoted at up to 540 MB/s, compatible with laptops and desktop machines, with three-dimensional flash and dynamic write acceleration; a system that starts in seconds, with a flexible high-speed single-level cell region used to reach those speeds; storage of up to four terabytes across the range for photographs, music and video; award-winning drives backed by thousands of hours of validation, dozens of qualification checks and a limited three-year warranty; a free imaging application for migrating data and compatibility with the maker’s own maintenance tool; hardware encryption at 256 bits meeting three named industry standards; and a discount of up to eighty per cent on a backup subscription for buyers of certain capacities.
Three standards, named
The fifth bullet names three published encryption standards. That is the most specific claim on this page and one of the most specific in the lot. A workplace policy is normally written against exactly those names, so a drive that lists them can be checked against a requirement instead of argued about. It costs the page nothing and it is worth more than another rate would have been.
Accelerating writing, without a writing figure
The first bullet is about how quickly the drive accepts data, and no figure for accepting data appears anywhere on the page. Part of the flash is used one bit per cell to take writes fast and empties afterwards, which is a real mechanism and a good one to name. It describes the opening of a copy. What the copy settles to, and what the peak is in the first place, are both unstated.
Validation hours are not failure hours
Thousands of hours of validation and dozens of qualification checks describe work the maker did before selling the drive. A population statistic describes how often drives fail afterwards. The two are easy to read as one, they are not the same claim, and only the first is on this page.
Four terabytes, and which drive that is
The second bullet names a ceiling for the range. The title sells one terabyte. Range ceilings are legitimate and they are not model specifications, so the capacity line above records the figure in the title and notes where the larger one comes from.
Before ordering
Ask for the written total and a rate for writing. The term, the encryption and the mechanism are all published; the two numbers that would place this drive against the next one are not.
Availability
Priced from 159 € to 165 € across the German, French, Italian and Spanish Amazon stores the day this page was checked.
It is stocked on the American and British Amazon stores as well, in that country’s own currency. The range above leaves those out: it counts euro stores and no others.

Where it holds up, and where it stops
Strengths
The encryption is named to three published standards rather than described as secure, which makes it checkable against a workplace requirement
A term of three years is published, and it is the one endurance quantity that carries an obligation
The write acceleration mechanism is named and its memory arrangement described, which explains where the opening speed of a copy comes from
Compromises
No writing figure at all, on a page whose first bullet is entirely about accelerating writing
Neither a written total nor a population statistic, so the three-year term stands without either figure normally published beside it
Two of the six bullets are about bundled software and a discount on it
Specifications
Capacity
1 TB — printed twice in the title, in the maker’s unit and reported here in that unit. The second bullet separately names up to 4 TB, which is the ceiling of the range rather than this drive
Form factor
2.5-inch — printed in the title, which also names laptops and desktop machines as the intended homes for the drive
Height
Not published on the listing — no thickness in millimetres appears, on a page that names laptops in its title and its second bullet
Stated sequential read figure
Up to 540 MB/s — printed in the title. No bullet repeats it, and the first describes the effect rather than the figure
Stated sequential write figure
Not published on the listing — the first bullet names dynamic write acceleration and the flash it uses, and gives no rate for the writing it accelerates
Stated random IOPS
Not published on the listing — no figure in IOPS appears in the title or in the six bullets
TBW rating
Not published on the listing — no total in terabytes written appears, on a page whose third bullet publishes the term such a total normally bounds
Stated MTBF
Not published on the listing — no figure in hours appears; the third bullet offers thousands of hours of validation and dozens of qualification checks instead, which count effort rather than failures
DRAM cache presence
Not published on the listing as memory on the drive — the first bullet names a flexible high-speed single-level cell region used to accelerate writing, which is part of the flash and not a separate memory chip
Controller family
Not published on the listing — no controller is named; the memory is described as three-dimensional flash in the title and the controller behind it is not mentioned
Warranty length
Three years, limited — stated in the third bullet, alongside the validation and qualification claims that precede it

The questions that come up before an order
What does hardware encryption to a named standard give that a password does not?
It puts the encryption in the drive rather than in the operating system, so the data on the flash is unreadable without the key even if the drive is removed and fitted elsewhere. Naming the published standards matters because a workplace policy is usually written against those names rather than against a promise of security. This page names three of them, which is unusually specific for this shelf.
Is dynamic write acceleration the same as a cache?
It is a way of using one. Part of the flash is written one bit per cell, which is quick, and the drive moves that data into the slower three-bit arrangement afterwards. How much of the flash is used that way can change with how full the drive is, which is what the word dynamic refers to. It is not a separate memory chip, and the page does not claim one.
2 TB · 2.5-inch · SATA III · up to 540 MB/s read · up to 500 MB/s write · three-year warranty ending at a written total the page never states · no MTBF · no controller named
A two-terabyte drive whose warranty is explicitly limited by a written total, and whose page never says what that total is.
Best for: A desktop machine or a laptop needing two terabytes on this interface, bought by someone who will ask for the written total before relying on the term.
1 TB · 2.5-inch · SATA III at 6 Gbps · up to 550 MB/s read · up to 500 MB/s write · TBW rating of up to 480 TB · 2 million hours MTBF · shock resistance to 1500 G · no warranty term
A one-terabyte drive that publishes both sequential figures, a written total, a population statistic and a shock figure with its duration, and that names no warranty term at all.
Best for: A notebook or a desktop machine that is knocked about, where a shock rating and a written total matter and the term will be checked with the seller.
1 TB · 2.5-inch · SATA III at 6 Gb/s · up to 550 MB/s read · three years, in a bullet that ends before it names what lasts · no write figure, no TBW, no MTBF
A one-terabyte drive whose interface and reading figure are published twice over, and whose fifth bullet gives three years and a limitation and then stops before naming what runs for three years.
Best for: An older laptop or desktop machine where a spinning drive is being replaced and a stated term matters more than a full sheet of figures.
