The Patriot P200 is a solid-state drive in the 2.5" form factor, launched on July 17th, 2019. It is available in capacities ranging from 128 GB to 1 TB. This page reports specifications for the 128 GB variant. With the rest of the system, the Patriot P200 interfaces using a SATA 6 Gbps connection. The SSD controller is the SM2258XT from Silicon Motion, a DRAM cache is not available. Patriot has installed 64-layer TLC NAND flash on the P200, the flash chips are made by Micron. 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 handled more quickly. The P200 is rated for sequential read speeds of up to 500 MB/s and 430 MB/s write; random IO reaches 60K IOPS for read 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. Patriot guarantees an endurance rating of 80 TBW, a good value.
