Toshiba Memory America is announcing expansion of its portfolio of SSDs for data centers with the addition of new PCIe NVMe and SATA SSDs that feature Toshiba BiCS FLASH 64-layer TLC 3D NAND in several form factors. Their new CD5, XD5 and HK6-DC SSDs provide robust performance and reliability for read-intensive usage scenarios such as streaming media, big data analytics and NoSQL databases, as well as having lower operating power requirements. These new series of data center SSDs feature Toshiba end-to-end vertical integration to ensure quality and reliability.
According to Neville Ichhaporia, Toshiba’s director of client and data center SSD marketing, “Today’s data centers continually face heavy workloads and require high reliability, low-power solutions able to deliver consistent application performance. Our new lineup of BiCS FLASH-based NVMe and SATA SSDs address these demands with a combination of great performance, low latency and high reliability to provide efficient storage solutions for cloud environments.”
Toshiba’s new series of NVMe SSDs are geared to multiple data center workload profiles. The CD5 is being offered in capacities ranging from 960GB up to 7680GB in a U.2 form factor, providing random read speeds of up to 500,000 IOPS and random write speeds of up to 35,000 IOPS. Sequential read speeds are stated as up to 3140MB/s, with sequential write speeds of up to 1980MB/s, and these speeds are attained within a 9-14W power envelope.
The XD5 Series is built on the M.2 22110 form factor, and supports capacities up to 3.84TB. The XD5 provides sequential read speeds of up to 2600MB/s, and sequential write speeds of up to 890MB/s, all within a 7W power envelope. The CD5 and XD5 SSDs are optimized for performance consistency and low latency when handling read-intensive workloads, and are geared toward Open Compute Platform (OCP) and hyper-scale/cloud applications.
Toshiba’s HK6-DC Series are SATA 6Gb/s SSDs that will be available in capacities of 960GB, 1.92TB and 3.84TB. The HK6-DC series are low latency and read-intensive optimized, providing random read speeds of up to 85,000 IOPS and sequential read speeds of up to 550MB/s – this is some 400X superior to a 15,000 RPM high-performance HDD, as well as being another improvement over previous generations of SATA SSDs.
These new data center SSDs all feature power loss protection, and support cryptographic secure erase support for removal of data. They also utilize AES 256-bit encryption to encrypt data without the performance hit often associated with software-based encryption. Toshiba is backing these new data center SSDs with a five-year limited warranty. Toshiba will begin shipping samples of the CD5, XD5 and HK6-DC in Q2 of 2018 to select customers.
