ATP Launches M.2 NVMe SSDs: 3D MLC, SMI, Extreme Temps, Up to 2.5 GB/s

ATP has introduced its new lineup of SSDs aimed at industrial applications and are designed to withstand harsh environmental conditions, such as extreme temperatures and humidity. The new ATP M.2 NVMe drives use 3D MLC memory to maximize their endurance, and are driven by what we believe to be a SM2260 controller. They come in come in M.2-2280 form-factor (as the name suggests), use a PCIe 3.0 x4 interface and demonstrate a rather high read performance of up to 2.5 GB/s. Such performance levels are rare for industrial-grade SSDs, as they typically rely on a SATA interface and offer fairly conservative performance levels to match.

ATP’s M.2 NVMe family of SSDs consist of two sub-families: the N600c for commercial applications and the N600i for industrial applications. The drives are based on Micron’s 3D MLC NAND memory (certified to work in extreme conditions in case of the N600i) as well as a Silicon Motion controller that ATP does not disclose. Based on performance figures (see below) and the fact that we are dealing with SSDs for commercial and industrial workloads, it is highly likely that the drives use SMI’s time-proven SM2260 SoC that supports LDPC as well as RAID data recovery for advanced error correction.

ATP’s M.2 NVMe N600c and N600i SSDs will be available in 128 GB, 256 GB, 512 GB and 1 TB configurations. As for performance, ATP specs the drives for up to 2.5 GB/s sequential read speeds and up to 1.1 GB/s sequential write speeds (when pSLC caching is used). When it comes to random performance, the M.2 NVMe SSDs are rated for up to 100K read/write IOPS (which is a rather conservative figure for SM2260-based drives).

The M.2 NVMe N600i series is designed to withstand up to 16.4 G vibration and 1500G/0.5ms shock, extreme temperatures from –40°C to +85°C, as well as high humidity (5%-95% RH, non-condensing at 25°C). To put extreme temperatures into perspective, the M.2 NVMe N600i can operate in Antarctica (but not in “winter”) or in the Lut Desert in Iran. In the real world, the SSDs will serve inside space-constrained industrial, embedded or commercial PCs, servers, and military-grade equipment. Since such applications are barely write intensive, the drives are rated for up to 1.75 DWPD (but ATP does not disclose over which period). Meanwhile, the M.2 NVMe N600c series is aimed at commercial applications, so they are not designed for extreme environments: their operating temperature range is between 0°C and 70°C, but they can sustain up to 2.1 DWPD.
