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.

    The comment section should be filled with people who want to buy this, since many here just want raw endurance out of their NAND cells. :D Reply

    This is going to cost too much for the common people. Reply

    I'll wait for the 3D SLC version thanks. Reply

    YAAAAAASSSSSSSSSSSSSSS!!! An SLC SSD with extreme ENDURANCE for only the cost of a kidney and a ritualistic sacrifice of my firstborn! Reply

    If 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. Reply

    I'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.

    People want their machines to survive for years with current professional usage i.e. using anything that caches which is most applications (including firefox which writes tens of GB a day) and also being able to shut it off more months if not years (i.e. a laptop which you use as a spare)

    Previous planar TLC, especially small drives had real issues. What salvaged TLC was large process 3D NAND. Currently QLC is going through the same issue, with no new tech in site to salvage it. What people are complaining about is exactly that -- not the mid range -- accepting worst case as the new normal, especially when that worst case isn't even remotely proportionately cheaper.

    So don't intentionally misconstrue legitimate gripes with shit QLC

    "People want"
    No they don't. You want. If people wanted their marketing teams would have asked for these products. As it stands, we are getting QLC because 'people' just want a SSD with low endurance at a low price.

    Reality is that manufacturers sell what they want to sell and people buy it, much more often than you are apparently willing to realize.

    The reason 4K became the HDTV standard was because it was easier for manufacturers to use existing 1080-oriented production equipment. It was nothing to do with the resolution itself, beyond it being higher. 1080, in fact, was not a good move for consumers because it would have made a lot more sense to go from 720 to 1440 and then stop for HDTV — until compressor sophistication, bandwidth, color depth, and other factors caught up with pixel density.

    The piddling Jaguar processor used for so long by Sony and MS is also often cited as an example of companies peddling what they want to sell to a largely captured market.
