OVERVIEW

SiliconDrive combines all the high

performance, high reliability, and multiyear

lifecycle benefits of the standard SiliconDrive

with a comprehensive suite of patented and

patent-pending technologies that provide

multiple security options to safeguard

application data and software IP in embedded

systems.

Applications requiring advanced levels of

security such as data recorders, wearable and

field computers, medical monitoring and

diagnostic equipment, POS systems, and

voting machines are able to activate security

options to protect application data and

software IP from theft, falling into the wrong

hands from deployments in high-risk areas,

corruption, and accidental or malicious

overwrites.

PowerArmor prevents data corruption and loss

from power disturbances by integrating

patented technology into every SiliconDrive.

SiSMART acts as an early warning system to

eliminate unscheduled downtime by constantly

monitoring and reporting the exact amount of

remaining storage system useful life.

SiSecure is a comprehensive suite of user-

selectable security technologies that solves

the critical need for robust storage security for

embedded systems applications that have a

small footprint and low-power requirement.
