Trio Of SSDs Geared For Data Centers!


To address the increasing demand for flash storage in data centers, Toshiba has unveiled three new SSDs featuring BiCS FLASH 64-Layer 3D Flash Memory. The company said these SSDs are ideal for data centers which continually face heavy workloads and require high reliability, low-power solutions for consistent application performance.

The new SSDs 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.

Called CD5, XD5 and HK6-DC, the SSDs provide PCIe and SATA interfaces, and are available in 2.5-inch and M.2 form factors.


The SSDs utilize 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.

“Demand for flash storage in data centers continues to grow rapidly – with capacity shipped into the enterprise expected to increase at a 58 percent CAGR through 2021,” said Jeff Janukowicz, IDC Research Vice President for Solid State Drives and Enabling Technologies. “In order for hyperscale, virtualization, automation/orchestration and software-defined storage applications to thrive, cloud data centers must meet specific workload requirements. Toshiba’s latest data center SSDs are designed to help customers address these demanding environments and realize the most value from their flash storage.”

CD5 Series

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.

XD5 Series

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 optimized for low latency and performance consistency in read-intensive workloads, and targeted at Open Compute Project (OCP) and hyper-scale/cloud applications.

HK6-DC Series

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 optimized 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 the previous generation SATA SSDs“, claimed Toshiba.

The SSDs feature power loss protection and support cryptographic erase support for secure removal of data.

They also utilize AES 256-bit data to encrypt data securely without the performance impact associated with software-based solutions. The new SSDs also include a five-year limited warranty.
