La série Kingston KC2500 fait partie des meilleurs SSD NVMe PCIe x4 pour le grand public, avec des vitesses plus élevées que le Samsung PM981 que l'on retrouve souvent sur les ultrabooks haut de gammes et les portables de jeu. Ses températures peuvent monter à 70 °C en cas de sollicitations, si bien que les sollicitations soutenues sur un PC portable peuvent ne pas être idéales. Et si nous n'avons pas noté de problème de throttling, la présence d'un dissipateur thermique pourrait être une bonne chose afin que la température soit plus confortable.
