The Kingston A400 is a solid-state drive in the 2.5" form factor, launched on January 11th, 2018. It is only available in the 480 GB capacity listed on this page. With the rest of the system, the Kingston A400 interfaces using a SATA 6 Gbps connection. The SSD controller is the SM2259XT2 from Silicon Motion, a DRAM cache is not available. Kingston has installed 128-layer TLC NAND flash on the A400, the flash chips are made by YMTC. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The A400 is rated for sequential read speeds of up to 500 MB/s and 450 MB/s write; random IOPS reach up to 90K for reads and 35K for writes.
The SSD's price at launch is unknown. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. Kingston guarantees an endurance rating of 160 TBW, a typical value for consumer SSDs.
