CNEX Labs Achieves Industry-First 1.5 Million IOPS NVMe SSD Performance featuring Toshiba Memory Corporation 3D TLC Memory with TSV Technology


Best-in-class SSD controller and NAND technology combine to deliver performance across key metrics – large capacity, low latency, high bandwidth, high IOPS per Watt

SANTA CLARA, Calif. – August 8, 2017 – Tuesday at Flash Memory Summit 2017, CNEX Labs, Inc., a private semiconductor company providing solid-state storage controllers and software for cloud, hyperscale, and enterprise data centers, announced support of Toshiba Memory Corporation BiCS FLASH™ 3D flash memory with through Silicon Via (TSV) and 3-bit-per-cell (triple-level cell, TLC) technology on the CNEX Westlake Plus NVMe solid-state drive (SSD) controller platform featuring 1 gigatransfer (1 billion transfers) per second (GT/s) NAND interface speed, and demonstration of record-breaking 1.5 Million I/O’s per second (IOPS) read performance.

“Combining a 48-layer 3D flash process and TSV technology has allowed us to increase product read and programming bandwidth while achieving low power consumption”, said Hiroo Ohta, Technology Executive from Toshiba Memory Corporation. “The power efficiency of a single TSV package is approximately twice that of the same generation BiCS Flash memory fabricated without TSV technology.”

“CNEX is working closely with Toshiba Memory Corporation, the NAND Flash industry leader, and is excited to demonstrate the latest innovation in flash technology coupled with CNEX’s advanced NVMe SSD controller to deliver the highest performance and lowest power in the industry,” said Dr. Alan Armstrong, CEO and Co-Founder of CNEX Labs. “Increases in SSD capacity typically are coupled with increased power consumption and reduced performance — CNEX’s NVMe SSD controller and Toshiba Memory Corporation TSV technology reverse this trend, delivering enterprise and data center customers high capacity drives with low power, combined with IOPS per terabyte (TB) scalability.”

CNEX Labs controller technology not only supports existing BiCS FLASH™ 3D TLC flash, but also supports emerging technologies like TSV to bring unprecedented levels of performance to the high-growth cloud and enterprise markets.
