Crucial

Crucial names the mechanism and rarely quantifies it

The Crucial drives here

A Gen 4 NVMe drive, a portable SSD and a 2.5-inch SATA drive.

Terms and standards, printed

The NVMe drive states a five-year limited term. The SATA drive states three years, names its write-acceleration mechanism and lists three encryption standards by name, which is the most specific claim in that family. The portable drive publishes a drop height of two metres and names the backup arrangements it ships with.

The figures behind them

None of the three publishes a written total or a population statistic, so the terms have nothing beside them to be measured against. Two of the three publish a reading rate and no writing rate. The NVMe page fills its remaining bullets with percentage comparisons against drives it never names, and the portable drive stops its interface designation one word short of a generation.

    1 TB · 2.5-inch · up to 540 MB/s read · dynamic write acceleration named · 256-bit hardware encryption to three named standards · three-year limited warranty · no write figure, no TBW, no MTBF

    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.

    Best for: A machine where encryption to a named standard is a requirement and the drive will be read from far more than it is written to.

    A one-terabyte Gen 4 drive with a five-year term and a single sequential figure, whose remaining bullets compare it in percentages against drives the page never names.

    Best for: A laptop or a handheld where a long term and a stated efficiency claim matter, and where receiving large files is not the daily job.

  • Portable SSDs

    Crucial X9 1 TB, a drop height and a generation left unfinished

    1 TB · USB-C 3.2, generation not published · up to 1050 MB/s read · drop resistance to 2 m · one lead named, no length · no write figure · no TBW, no MTBF, no warranty

    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.

    Best for: A laptop bag where a drive gets knocked about, and where the published drop height and the named backup arrangements matter more than a second rate.
