1.0 Introduction
Virtium TuffDrive™ eUSB SSDs are ideal solutions for server, networking, embedded and industrial
applications that require a modest amount of storage and require a widely supported USB2.0
interface. Typical applications include operating system and file storage, system level diagnostics, or as
a backup repository for data in DRAM in the event of a system-level power-down.
