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 absorbed more quickly. The PX500 is rated for sequential read speeds of up to 2,050 MB/s and 1,650 MB/s write; random IO reaches 171K IOPS for read and 143K 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. Goodram guarantees an endurance rating of 660 TBW, a good value.
