Toshiba Memory offers 3D flash memory-based PCIe NVMe and SATA SSDs

Adding to its portfolio of solid-state drives (SSDs) for data centres, Toshiba Memory offers 3D flash memory-based PCI Express NVMe and SATA SSDs in multiple form factors.

The CD5, XD5 and HK6-DC SSDs enable infrastructure managers to address performance and workload demands, says Toshiba. They offer robust performance and reliability with lower operating power for read-intensive applications such as NoSQL databases, big data analytics and streaming media.

“Demand for flash storage in data centres continues to grow rapidly – with capacity shipped into the enterprise expected to increase at a 58 per cent CAGR through 2021,” said Jeff Janukowicz, IDC Research Vice President for Solid State Drives and Enabling Technologies.  “In order for hyperscale, virtualisation, automation/orchestration and software-defined storage applications to thrive, cloud data centres must meet specific workload requirements,” he says. 

Toshiba’s SSDs use its next-generation BiCS FLASH 3D flash memory, which is based on the company’s 64-layer architecture and uses three-bit-per-cell (triple-level cell, TLC) technology. The CD5, XD5 and HK6-DC SSD families are designed with end-to-end vertical integration to deliver quality and reliability, adds Toshiba.

The PCIe NVMe SSDs are designed for multiple data centre workload profiles.

The CD5 series supports capacities ranging from 960Gbyte in a U.2 form factor, delivering 500,000/35,000 random read/write IOPS and up to 3,140/1,980Mbyte per second sequential read/write performance within a nine to 14W power envelope.

The XD5 Series is a small footprint M.2 22110 form factor SSD that supports capacities up to 3.84Tbyte and delivers up to 2,600/890Mbyte per second sequential read/write performance in a 7.0W power envelope. These SSDs are optimised for low latency and performance consistency in read-intensive workloads, and targeted at open compute platform (OCP) and hyperscale/cloud applications.

The HK6-DC series is a 6Gbit/s SATA SSD and is available in 960Gbyte, 1.92Tbyte and 3.84Tbyte capacities. This read-intensive, latency-optimised SSD delivers up to 85,000 random read IOPS and up to 550Mbyte per second 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), points out Toshiba. 

The data centre SSDs feature power loss protection and support cryptographic erase support for secure removal of data. They also utilise AES 256-bit data to encrypt data securely without the performance impact associated with software-based solutions. They carry a five-year limited warranty.

Toshiba will begin shipping samples of the CD5, XD5 and HK6-DC SSD families to select customers in Q2 2018.
