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 50K 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 300 TBW, a relatively low value compared to other SSDs.
