The Ultrastar™ SSD400S series is the latest generation of enterprise-class solid-state drives from Hitachi Global Storage Technologies, based on SAS and Fibre Channel interfaces, using enterprise-class SLC NAND flash and advanced durability management firmware, providing up to 535MB/s of continuous read speed and 500MB/s of continuous write speed, and up to 46K (read)/13K (write) random IOPS. The product line has an ultra-low annual failure rate (AFR), which can withstand up to 35PB of random writes, which is equivalent to writing 19.2TB of data every day for five years!
The SSD400S series provides high‑performance, high‑reliability solid‑state storage for enterprise servers and high‑performance computing. It supports SAS 6 Gb/s or FCAL 4 Gb/s interfaces, delivers up to 535 MB/s sequential read and 500 MB/s write speeds, and achieves 46 K read / 13 K write IOPS.
Designed for durability, the drive features SLC NAND, T10 end‑to‑end data protection, XOR power‑loss data management, a 0.44 % annual failure rate, and an endurance of up to 35 PB of random writes. It operates at a typical 5.5 W power draw and meets EcoTrac environmental standards. This manual is written in Chinese.
