Greenliant revealed on Wednesday that it has started shipments of its new industrial-grade ArmourDrive M.2 SSDs. The enhanced-durability drives are rated to operate in a much wider range of temperatures than commercial drives and are available in both NVMe and SATA formats, with capacities from 240 GB up to 1.92 TB.
Greenliant’s ArmourDrive 88PX-series NVMe M.2-2280/PCIe 3.0 x4 SSDs and ArmourDrive 87PX-series SATA M.2-2280 SSDs are designed to operate in temperatures between -40°C and +85°C. The drives use 3D TLC NAND memory, feature a DRAM cache, and are based on an unknown/unlisted controller that support LDPC-based ECC, end-to-end data protection, dynamic and static wear leveling, AES-256/TCG OPAL encryption, and Secure Erase capabilities.
As far as performance is concerned, the Greenliant ArmourDrive 88PX NVMe SSDs are rated for up to 3400 MB/s sequential read speeds as well as up to 1100 MB/s sequential write speeds. Meanwhile, the Greenliant ArmourDrive 87PX SATA SSDs offer up to 550 MB/s sequential read speeds as well as up to 520 MB/s sequential write speeds.

Greenliant is not the first company to ship TLC-based M.2 drives that can work in extreme environments, but it is among the first suppliers to start selling 1.92 TB drives for industrial temperature ranges. Building high-capacity SSDs for industrial applications is not particularly easy since they use multi-layered chips all of which should work fine when it is extremely cold or extremely hot.
The company does not disclose prices of its ArmourDrive 88PX NVMe and ArmourDrive 87PX SATA SSDs, as prices depend on the quantity ordered as well as other factors.

Without a price and endurance rating, they may as well not bother listing the rest of the specs.FastCarsLike - Sunday, April 26, 2020 - link
Agreed. Although it's neat they suggest -40°C and +85°C as the operating range. On the series brief they mention 3K P/E cycles, for MLC, typical maximum PE-cycle-per-block numbers range from 1500 to 10,000. So basically cheap TLC that is engineered to match up with MLC. If you where that worried about write endurance, I think people would forgo all that, and buy SLC up front, where the PE cycle is ~100,000 before failure.
