Toshiba announces two new series of SSDs

Toshiba announces two new enterprise solid state drives series, the HK3E2 for value-endurance workloads and the HK3R2 drive for read intensive workloads. These 6Gbit/s SATA Enterprise SSDs join Toshiba’s portfolio of enterprise storage solutions featuring a variety of endurance ratings to meet the needs of specific application requirements and customer environments.


The HK3E2 series is available in capacities up to 800GB in a 2.5-inch standard form-factor (7mm Z-height). The HK3E2 is designed for mainstream enterprise applications such as exchange mail servers, web servers, database servers, indexing servers, and data center storage workloads. The HK3E2 Series has a three drive writes per day (DWPD) endurance specification for five years, with random 4KiB enterprise workload.

The  HK3R2 series is available in capacities up to 960GB in a 2.5” standard form-factor (7mm Z-height). The HK3R2 is designed for read intensive applications and workloads such as read caching, video streaming and data center storage. The HK3R2 has an endurance rating of one DWPD for five years with a random 4KiB enterprise workload.

Both SSDs are equipped with power loss and end-to-end data protection features with a common controller and mechanical design. Additionally, both the HK3R2 Series and the HK3E2 Series incorporate Toshiba’s proprietary QSBC (Quadruple Swing-By Code) error-correction technology, an error correction code (ECC), which helps protect data from corruption caused by NAND flash memory media wear.

The series also feature both a Toshiba-designed SATA SSD controller and Toshiba 19nm second-generation MLC NAND flash memory.
