Press Releases » Member Releases » SSD

The PX03SN is ideally suited for media streaming, read-caching, and low-to-mid duty primary storage

IRVINE, Calif. — December 2, 2013 — The Storage Products Business Unit of Toshiba America Electronic Components, Inc., a committed technology leader, announces a new enterprise read-intensive solid state drive (eSSD) – the PX03SN. Designed to support the widest possible range of read-intensive applications, the PX03SN is available in capacities of up to 1.6TB1 and supports one full drive write per day2. The new 2.5-inch form factor SAS interface eSSD is designed for readintensive applications, server storage and caching applications, and storage systems where customers are looking for a balance between cost, endurance and performance.

Optimized for read-intensive, read-caching, and low-duty storage applications, the newest addition to the eSSD family features a 12 Gbit/s3 SAS interface. The PX03SN reflects Toshiba’s continued storage innovation and is optimized for its target segment with NAND flash processes, density, endurance and interface implementation.

“Toshiba gives customers a ‘one stop shop’ capability for their storage requirements, including both SSDs and hard disk drives (HDDs) for customers’ mobile and enterprise needs,” said Don Jeanette, senior director of marketing at Toshiba Storage Products Business Unit. “We are seeing increasing demand for eSSDs that offer a SAS interface and meet customers’ endurance and price requirements without sacrificing performance.”

The PX03SN 200/400/800GB and 1.6TB, read-intensive customer samples will begin shipping this month. For more information on Toshiba’s line of industry leading SSDs, HDDs and SSHDs, visit To connect with Toshiba Storage, visit the corporate blog at

1   Definition of capacity: Toshiba 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 = 1,073,741,824 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, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.

2   One full drive write per day means the drive can be written and re-written to full capacity 1 time a day for five years, the stated product warranty period. Actual results may vary due to system configuration, usage, and other factors.

3   Read and write speed may vary depending on the host device, read and write conditions, and file size.
