Greenliant Launches EnduroSLC SSDs with Up to 250K P/E Cyclesby Anton Shilov on December 11, 2018 3:00 PM EST
Greenliant, a developer of special-purpose NAND-flash storage devices, this week introduced its new lineup of ultra-high endurance SSDs. The NANDrive SSDs are aimed at write-intensive industrial applications, and utilize the company’s proprietary EnduroSLC technology and in-house controllers.
Greenliant’s NANDrive SSDs offer endurance ratings of of 50K, 100K, or 250K per-cell program/erase (P/E) cycles, which is well beyond everything offered by "conventional" NAND flash memory manufactured today (SLC is typically rated for ~100K, MLC ~10k, and TLC ~3k).
Right now, the only other storage solutions from Greenliant that offer 250K P/E cycles are their GLS85VM eMMC 5.1, which are available at up to 32GB capacities and offer sequential performance of up to 185 MB/s reads and 140 MB/s writes in HS400 mode. The drives are designed to operate at industrial temperatures between -40°C and +85°C, so they can address virtually any type of application.
Typically, SLC NAND is rated for 100K P/E cycles, but Micron and Sun introduced SLC NAND rated for a million of P/E cycles almost exactly 10 years ago. Companies like Samsung and Toshiba these days offer enterprise-grade Z-NAND and XL-Flash memory that is designed to physically withstand tens of thousands of P/E cycles while offering high performance.
Greenliant does not make its own memory dies, so the EnduroSLC tech allegedly uses enterprise-grade NAND chips produced by an unnamed manufacturer. The company does not disclose a lot of information about its technologies, but as far as we can tell, Greenliant uses a lot redundant raw NAND memory along with a special in-house-designed controller supporting an elaborate feature set and sophisticated algorithms.
Greenliant’s GLS85VM eMMC 5.1 NANDrive SSDs with endurance of 50K, 100K, and 250K P/E cycles are currently available to select customers with select product engagements.
