The Kingston DC500M is a solid-state drive in the 2.5" form factor, launched on March 18th, 2019. It is available in capacities ranging from 480 GB to 3.8 TB. This page reports specifications for the 480 GB variant. With the rest of the system, the Kingston DC500M interfaces using a SATA 6 Gbps connection. The SSD controller is the PS5012-E12-27 from Phison, a DRAM cache chip is available. Kingston has installed 64-layer TLC NAND flash on the DC500M, the flash chips are made by SpecTek. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The DC500M is rated for sequential read speeds of up to 555 MB/s and 520 MB/s write; random IOPS reach up to 98K for reads and 58K for writes.
At its launch, the SSD was priced at 126 USD. The warranty length is set to five years, which is an excellent warranty period. Kingston guarantees an endurance rating of 1139 TBW, a high value.

Notes

Drive:

This drive uses six tantalum capacitors A337C (330 μF 10 V) for it's Power Loss Protection Circuitry.
Since this drive had more than 512GB of storage in the 480GB version, it had a much larger over-provisioned area, and i think it could also be allocated for a static pSLC Cache for higher performance, reliability and endurance

Controller:

2 main cores using Cortex-R5 clocked at 667 MHz with CoXProcessor technology (one additional dual-core) Cortex-R5 clocked at a lower clock for better efficience.

NAND Die:

Usually lower endurance ratings than Micron's counterpart
