1.Executive Summary
The Loongtion M.2 NVMe Series Solid State Drive (cacheless/DRAM-less design) is a high-performance, power-efficient storage solution designed for industrial, embedded, medical, and commercial applications. Manufactured by Ningbo Loongtion Intelligent Technology Co., Ltd. (Loongtion®), this drive uses a China-domestic controller with a DRAM-less architecture, Triple-Level Cell (TLC) NAND flash memory, and a PCIe 3.0 x4 interface compliant with the NVMe 1.4 protocol.
Available in capacities from 256 GB to 2 TB and offered in M.2 2280 and M.2 2242 form factors, the Loongtion M.2 NVMe SSD delivers the following minimum sequential read speeds: ≥1500 MB/s (256 GB), ≥2000 MB/s (512 GB), ≥2200 MB/s (1 TB), and ≥2500 MB/s (2 TB). Minimum sequential write speeds range from ≥700 MB/s (256 GB) to ≥1800 MB/s (2 TB). The drive is engineered for reliability across extreme environments, with an industrial operating temperature range of –40°C to 85°C and a 5-year warranty.
Key attributes include low power consumption (sleep power as low as 0.3 W), robust endurance with Total Bytes Written (TBW) up to 1400 TB for the 2 TB model, and support for TRIM, NCQ, S.M.A.R.T., and an optional custom-configurable soft self-destruct function. This whitepaper provides a technical overview of the architecture, specifications, performance, and system integration considerations for the Loongtion M.2 NVMe SSD.
