Toshiba XG5 Lineup NVMe SSDs With 64-Layer 3D BiCS Flash Memory at 2TB

Toshiba Memory America, Inc. (TMA), the US-based subsidiary of Toshiba Memory Corporation, has expanded its XG5 lineup of NVMe ⁽¹⁾ SSDs that are based on its 64-layer, 3D BiCS FLASH memory.

The XG5-P is a sub-series that doubles the capacity and is tuned to improve access range random R/W performance by up to 55% ⁽²⁾ over standard XG5 SSDs. It is designed to meet the needs of demanding PC, gaming and content delivery workloads and offers up to 2TB ⁽³⁾ of storage capacity while maintaining the promise of thin, fast storage with power efficiency.

To provide a comprehensive client SSD portfolio from basic laptop storage to read-intensive enterprise use cases, the company optimized the XG5 series to further accelerate applications requiring enhanced random I/O performance. Featuring a PCIe ⁽⁴⁾ Gen3 x4 lane and NVMe Revision 1.2.1 interface, XG5-P SSDs deliver performance, reaching up to 3,000MB/s of sequential read and 2,200MB/s of sequential write ⁽⁵⁾, and up to 320,000 read and 265,000 random write IO/s ⁽⁶⁾. Power efficiency was maintained to achieve these data transfer rates – XG5-P SSDs consume less than 60mW ⁽⁷⁾.

As company’s first 2TB M.2 SSD, the XG5-P series utilizes an in-house developed 1TB package solution that offers up to twice the maximum storage capacity of the standard XG5 series on the same 2.23mm thick single-sided M.2 2280 module. By maintaining a single form factor for all capacities across the complete XG5 and XG5-P product family, the firm makes it easier to design platforms that need flexible storage.

“Toshiba recognizes the need for engineering larger capacity, higher performance SSD solutions that target specific applications and use cases,” said Neville Ichhaporia, director, marketing, client and data center SSD, TMA. “With our latest flagship XG5-P series, we have once again raised the bar in client SSD storage by delivering NVMe SSDs that take workstation, gaming and content creation performance to the next level.“

Engineered with the reliability and stability, the XG5-P series will be available in 1TB and 2TB models.

Self-encrypting drive (SED) models ⁽⁸⁾ supporting TCG Opal Version 2.01 will also be offered, making the XG5-P series for a range of applications that prioritize performance, as well as business applications requiring security.

⁽³⁾ Definition of capacity: Toshiba Memory Corporation defines 1MB as 1,000,000 bytes, 1GB as 1,000,000,000 bytes and 1TB as 1,000,000,000,000 bytes. A computer OS, however, reports storage capacity using powers of two for the definition of 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 OS, such as Microsoft OS and/or pre-installed software applications, or media content. Actual formatted capacity may vary.

Read and write speed may vary, depending on the host device, read and write conditions, and file size. Toshiba Memory Corporation defines 1MB as 1,000,000 bytes and 1KB as 2¹⁰ bytes, or 1,024 bytes.
⁽⁶⁾ IO/s. Toshiba Memory Corporation survey based on random read and write speeds of 4KB units and the state of ‘SLC cache=ON’ under test conditions. Read and write speed may vary, depending on the host device, read and write conditions, and file size. TMC defines 1KB as 2¹⁰ bytes, or 1,024 bytes.
