Kingston DC400 960GB SSD review

1. Specifications

Kingston's Data Center 400 (DC400) SSD is the storage device we have in our labs today. This is the latest solid-state drive to join the family of Kingston's entry-level enterprise solutions, designed for read-intensive applications such as boot, web servers and lower data rate operational databases and analytics - especially in data center mixed workload environments where endurance and reliability are important.

The SSD uses an on-board DRAM acceleration cache to enable sustained IOPS to increase performance over a wide range of read/write workloads. The DC400 is based on 15nm MLC NAND and the quad-core Phison S10 controller. It is available in 400GB, 480GB, 800GB, 960GB, 1.6TB and 1.8TB capacities. The 400GB, 800GB and 1.6TB capacities are performance optimized with greater IOPs for faster application performance and reduced storage latency. The 1.8TB capacity read-intensive optimized model is factory-tuned for read-intensive workloads. This optimization is attributed to the amount of the NAND that is allocated to the overprovisioned area. The 960GB version we have in or hands today further allows us to set the amount of reserved NAND that will be used for overprovisioning through the software bundled with the drive, as we will see later on.

Additionally, DC400 SSD features reliability with end-to-end data path protection, SmartECC, SmartRefresh and firmware controlled power loss management. ("pFAIL").

Smart ECC is a RAID ECC technology used to recover uncorrectable errors. When a page is found faulty and flash ECC protection fails to recover the uncorrectable errors, the defective page will be reconstructed by the Smart ECC engine.

The DC400 is backed by a five-year limited warranty. Endurance for the DC400 SSD varies by capacity, with the 400GB rated for 422TB (0.57 DWPD), the 480GB rated for 257TB (0.30 DWPD), the 800GB rated for 860TB (0.58 DWPD), the 960GB rated for 564TB (0.32 DWPD), the 1.6TB rated for 1678TB (0.57 DWPD) and the 1.8TB rate for 1432TB (0.43 DWPD). Power consumption is stated as an average of 1.6W, and 1.5W at idle.
