The CD5, XD5 and HK6-DC SSDs are intended to enable infrastructure managers to address performance and workload demands by offering robust performance and reliability with lower operating power for read-intensive applications such as NoSQL databases, big data analytics and streaming media.
The line-up of SSDs uses Toshiba’s next-generation BiCS FLASH 3D flash memory, which is based on the company’s 64-layer architecture and uses 3-bit-per-cell (triple-level cell, TLC) technology. Additionally, the CD5, XD5 and HK6-DC SSD families are designed with end-to-end vertical integration to deliver quality and reliability.
The CD5 Series supports capacities ranging from 960GB to 7,680GB1 in a U.2 form factor, delivering 500,000/35,000 random read/write IOPS and up to 3,140/1,980MB/s sequential read/write performance within a 9-14W power envelope.
The XD5 Series is a small footprint M.2 22110 form factor SSD that supports capacities up to 3.84TB and delivers up to 2,600/890MB/s sequential read/write performance in a 7W power envelope. These SSDs are optimised for low latency and performance consistency in read-intensive workloads, and targeted at Open Compute Platform (OCP) and hyper-scale/cloud applications.
The HK6-DC Series is a 6Gbit/s SATA SSD and is available in 960GB, 1.92TB and 3.84TB capacities. This read-intensive, latency optimised SSD delivers up to 85,000 random read IOPS and up to 550MB/s sequential read performance. These performance numbers are more than 400 times better than those of a 15,000 rpm higher performance hard disk drive (HDD). They also represent continued improvements over previous generation SATA SSDs.
These SSDs feature power loss protection and support cryptographic erase support for secure removal of data. They also use AES 256-bit data to encrypt data securely without the performance impact associated with software-based solutions. The company will begin shipping samples of the CD5, XD5 and HK6-DC SSD families to select customers in Q2 2018.
