Goke Microelectronics has introduced its new NVMe SSDs based on Toshiba’s XL-Flash NAND memory. The new drives are aimed at applications that require an ultra-low latency as well as high reliability and availability.

Based on Goke’s proprietary 2311 controller and Toshiba’s XL-Flash NAND SLC flash memory, the company’s 2311-series SSDs feature capacities of up to 4 TB and promise to offer a 4K random read latency of less than 15 μs (an under 20μs was hit by prototype drives and the manufacturer plans to improve that) as well as a maximum sustained read/write bandwidth of up to 3/1 GB/s. When it comes to security, the controller supports SM2/3/4 and SHA-256/AES-256.

Goke’s 2311-series SSDs are the industry’s second family of drives (announced so far) featuring Toshiba’s XL-Flash 128 Gb XL (16 planes, 4 KB page sizes). This type of memory promises to significantly reduce read latency when compared to TLC 3D NAND based SSDs: from  20μs all the way to 15 μs in case of Gecko’s upcoming drives (or to 5 μs in an ideal case, based on Toshiba’s estimates).

Goke plans to start production of its 2311-series SSDs powered by Toshiba’s XL-Flash NAND memory sometimes in 2020. As the drives are aimed at select applications only, the maker does not disclose their pricing as it will depend on configuration and volumes.

    This will be good for databases, as databases are a bunch of random lookups. Reply

    I guess this is good for the big enterprise or web company like Google and Facebook where they have their DB all optimised. For normal web dev, I dont think it will make a huge difference. Reply

    "maximum sustained read/write bandwidth of up to 3/1 GB/s."

    So, could that be simplified to just 3 GB/s? ;)

    Or is that supposed to be 31 GB/s?

    It's read/write speed. Reply

    No and no.

    "as well as a maximum sustained read/write bandwidth of up to 3/1 GB/s."

    That's 3GBps read and 1GBps write.

    This is good to compete with Samsung and Intel in the ultra high performance SSD market for enterprise/datacenter. I am not sure who would select Goke over Intel or Samsung for enterprise. it would have to be about half the price I would think to get any real sales Reply

    @Anton (Article): "This type of memory promises to significantly reduce read latency when compared to TLC 3D NAND based SSDs: from 20μs all the way to 15 μs in case of Gecko’s upcoming drives (or to 5 μs in an ideal case, based on Toshiba’s estimates)."

    Are the latency values accurate (20us to 15 us)? This is a latency drop of 25%. Not bad, but not exactly comparable to the drop from HDD (>10ms on average) to SDD (<1ms initially). Also, this is being compared to TLC flash. If I recall correctly, MLC and SLC have lower latency than TLC. Depending on the cost, this kind of latency improvement seems a bit underwhelming.
