Toshiba Memory Expands NVMe SSD Portfolio Targeting Cloud Data Centers

New Power-Efficient XD5 Series Now Available in 2.5-inch Form Factor Supporting Capacity Options up to 3.84TB

SAN JOSE, Calif., OCP Global Summit, March 13, 2019 – Toshiba Memory America, Inc.,  the U.S.-based subsidiary of Toshiba Memory Corporation, announced availability of its XD5 Series NVMe™ SSD platform in a 2.5-inch1, 7mm low-profile form factor that is optimized for low-latency and performance consistency in read-intensive workloads. Developed for both data center and cloud environments, the new 2.5-inch form factor XD5 Series is ideal for NoSQL databases, large-scale-out data mining and analysis, and streaming applications. The XD5 Series is also well-suited for Open Compute Project (OCP) applications and systems.

Built on 64-layer BiCS FLASH™ TLC (3-bit-per-cell) 3D flash memory, and featuring a PCIe® Gen3x4 interface, the new XD5 SSD 2.5-inch option delivers sequential read performance up to 2,700 megabytes per second (MB/s) and sequential write performance up to 895MB/s with low active power consumption of 7 watts3. At one drive write per day4 (DWPD), the XD5 Series can write nearly 4 terabytes (TB) of random data daily for five years at a consistent performance rate. Random read/write performance is specified at 250,000/21,000 Input/Output Operations per Second3 (IOPS) respectively, making the XD5 Series a predictable and reliable solution for read-intensive or heavy transactional workloads.

The XD5 2.5-inch Series expands Toshiba Memory’s broad data center SSD portfolio and complements the previously released M.2 22110 form factor which supports 1,920 gigabyte (GB) and 3,840GB capacities2. The flash memory and controllers leveraged within the XD5 Series offer high reliability, data protection, end-to-end error detection and power-loss protection, and the product is backed by a five-year limited warranty.

“Today’s scale-out data centers address a range of dynamic workloads and require highly reliable, low-power solutions that are able to deliver consistent application performance,” said Neville Ichhaporia, senior director of data center and client SSD marketing for Toshiba Memory America Inc. “With the addition of the power-optimized XD5 2.5-inch solution in a 7mm profile, we continue to round out our broad NVMe portfolio to enable the cloud data center market with a variety of solutions to suit most every need.”

Toshiba Memory’s PCIe NVMe SSDs are designed for multiple enterprise and data center workload profiles and include the XD5 Series, the CD5 Series and the CM5 Series, which help customers address their demanding data environments and realize the most value from their flash storage. The key specifications for this portfolio include the following:

1 2.5-inch is the form factor of HDDs and SSDs and does not indicate the drive’s physical size.
2 Definition of capacity: Toshiba Memory Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 bytes = 1,073,741,824 bytes, 1TB = 240 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
3 Read and write speed may vary depending on the host devices, read and write conditions, and file size.
4 One full Drive Write per Day (DWPD) means that the drive can be written and re-written to full capacity once a day, every day, for five years (or the stated product warranty period). Actual results may vary due to system configuration, usage and other factors.
