The new single port, four-lane Z-SSD features Z-NAND chips that provide 10 times higher cell read performance than 3-bit V-NAND chips, along with 1.5GB LPDDR4 DRAM and a high performance controller. Armed with some of the industry’s most advanced components, the 800GB Z-SSD features 1.7 times faster random read performance at 750K IOPS, and five times less write latency – at 16 microseconds, compared to an NVMe SSD PM963, which is based on 3-bit V-NAND chips. The Z-SSD also delivers a random write speed of up to170K IOPS.
Due to its high reliability, the 800GB Z-SSD guarantees up to 30 drive writes per day (DWPD) for five years, or a total of 42 petabytes. That translates into storing a total of about 8.4 million 5GB-equivalent full-HD movies during a five-year period. The reliability of the new Z-SSD is further underscored by a mean time between failures (MTBF) of two million hours.
Samsung will introduce its new Z-SSD in 800GB and 240GB versions, as well as related technologies at ISSCC 2018 (International Solid-State Circuits Conference), which will be held February 11-15 in San Francisco.
