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.

Gasaraki88 - Tuesday, December 11, 2018 - linkThis is going to cost too much for the common people.
bubblyboo - Tuesday, December 11, 2018 - linkI'll wait for the 3D SLC version thanks.
Amandtec - Wednesday, December 12, 2018 - linkGodammnit DeathAngel - you stole my comment.
JoeyJoJo123 - Tuesday, December 11, 2018 - linkYAAAAAASSSSSSSSSSSSSSS!!! An SLC SSD with extreme ENDURANCE for only the cost of a kidney and a ritualistic sacrifice of my firstborn!
DanNeely - Tuesday, December 11, 2018 - linkIf you're OK with only a capacity measured in megabytes, there's plenty of inexpensive embedded flash available that uses cells large enough you don't even need to bother with implementing ECC.
JoeyJoJo123 - Tuesday, December 11, 2018 - linkI'll be frank, that was a thinly veiled facetious post, mocking those who constantly gripe about SSD endurance on the SSD articles.
Funny thing is, here's what should get them to come out of the woodwork and be clapping, since this is apparently what they want, and they aren't even here. As I suspected, they just wanted to complain/gripe about tech.
DanNeely - Wednesday, December 12, 2018 - linkI wasn't exactly being serious either.
Samus - Wednesday, December 12, 2018 - linkDont forget minuscule capacities
AdditionalPylons - Tuesday, December 11, 2018 - linkVery impressive! However, in my humble and very personal opinion, if I had an extremely write-heavy scenario I’d make a RAM disk, and use cronjobs for frequent backing up to other media internally, plus UPS. But maybe the simplicity of having a drop-in replacement for an existing storage solution is worth more to the target audience.
