Crucial P5 SSD 1TB, M.2

Geht es in unserem Storage-Forum um Empfehlungen für SSDs, fällt meist auch der Name Crucial: Gerade die MX500 für SATA oder die P1 mit QLC-Speicher können sich in ihren Segmenten einer gewissen Beliebtheit erfreuen. Dabei steht bei beiden Laufwerken ein gutes Preisleistungsverhältnis im Fokus. Anders sieht es bislang bei der Empfehlung von HighEnd-SSDs aus. Hier fällt der Name Crucial eher selten, obwohl doch der Mutterkonzern Micron durchaus den Speicher für viele Top-Modelle produziert. Mit unserem heutigen Testkandidaten, der Crucial P5, soll sich das ändern. Wie gut das funktioniert, überprüfen wir wie immer mit unserem Benchmark-Parcours.

Mostly good to very good M.2 SSD that allows itself a few slips in the performance test. Nevertheless, we recommend it, especially thanks to the mostly low price.

Crucial, who makes the MX500, our all-time favorite SATA SSD, has always been lagging behind the competition slightly when it comes to M.2 NVMe SSDs. Back in 2018, they released the QLC-based Crucial P1, which impresses with excellent price/performance, but can't compete with the various high-performance TLC offerings on the M.2 storage market. This changes with the Crucial P5, which is based on a completely new controller design that's been developed in-house at Micron, Crucial's parent company. The new controller, just called "DM01B2" for the lack of a better marketing name, is a modern 8-channel design with support for TLC and pseudo SLC caching. It also has full hardware-based encryption and reports data from two thermal sensors back to the host system—nearly all other M.2 NVMe SSDs only have one. As expected, the flash chips are provided by Micron. We've seen these 96-layer B27A 3D TLC chips on many SSDs before. Last but not least, 1 GB of fast DDR4-4266 provides storage for the SSD mapping tables, which helps with random write performance.
