Toshiba’s Storage Products Business Unit has announced it is expanding its enterprise Solid State Drives (eSSD) family with the PX-Series, which will debut in the fourth quarter with three models targeted for different applications. The new PX02SM, PX02AM, and PX03AN drives span a variety of price and performance points, but all offer power-loss protection and a 2.5-inch form factor.
Toshiba’s Storage Products Business Unit has announced it is expanding its enterprise Solid State Drives (eSSD) family with the PX-Series, which will debut in the fourth quarter with three models targeted for different applications. The new PX02SM, PX02AM, and PX03AN drives span a variety of price and performance points, but all offer power-loss protection and a 2.5-inch form factor.
PX02SM Overview
The PX02SM is the highest-performing of the new drives, and Toshiba’s first SSD to utilize 24nm eMLC (enterprise multi-level cell) NAND. The PX02SM is also Toshiba’s first 2.5-inch SSD with a dual-port 12Gb/sec SAS interface.
