1. Introduction

The Unigen Orion Series of Solid State Drives is designed specifically to address the demanding performance and reliability requirements of Enterprise‐Class storage and computing applications.

1.1 Product Overview

Built with a SandForce 1222 controller, the Unigen Orion Series SSD is ideal for energy‐efficient computing, reducing access times, and provides a durable alternative to conventional hard disc drives with superior shock resistance. The proprietary space manager architecture in the controller maximizes read/write data rate performance to and from the host and flash memory, eliminating firmware delays during sector read and write operations. The SandForce flash processor, combined with tailored firmware, provides complete ATA disk emulation, which ensures complete compatibility with a wide range of operating systems. Designed for ultimate reliability, Unigen Orion Series SSD’s have an excellent 1.5 million hour mean time before failure (MTBF) ensuring reliability over long term usage and come backed by a 3‐year warranty and dedicated technical and engineering support for OEM clients.
