General Description

The STEC™ Industrial Grade USB Flash Drive is more than just portable

storage. Tailored for industrial applications that require high reliability and data

throughput, it provides non-volatile, industrial grade solid-state storage in a

thumb-drive package. In addition, labeling allows for lot traceability and

complete info on the Bill of Materials.

The industrial grade USB flash drive is available in an ESD rated enclosure (with

LED light indicator) for applications that require NEBS Level 3 compliancy. The

ESD-rated enclosure has been tested for immunity from ESD for 8KV contact

and 15KV air.

The industrial grade USB flash drive is manufactured with STEC‟s state-of-the-

art, USB 2.0 flash memory controller, providing high data reliability and

endurance. Flash management software embedded in the controller emulates a

hard disk, enabling read/write operations that are identical to a standard, sector-

based hard disk. Sophisticated wear leveling algorithms ensures greater flash

endurance, while automatic bad block management and a built-in ECC Engine

ensure the highest data reliability. Based on a BCH error correct algorithm, the

ECC engine can correct up to 16-bit errors per 1 Kbyte.

The industrial grade USB flash drive with its high performance, high reliability

and low cost per megabyte is the product of choice in embedded applications,

such as Gaming, POS Workstations, Networking Equipment and Industrial PCs.

The industrial grade USB flash drive is fully customizable to add a company

logo, graphic design, or text. In addition, STEC offers value-added services to

OEM customers, such as pre-loaded content and controlled Bill of Materials.
