FFD™ 2.5" SCSI
Smallest, Rugged SCSI Solid-State Flash Disk
Technology Overview
M-Systems’ Fast Flash Disk (FFD) 2.5” SCSI disk is a state-of-the-art solid-state disk
based on NAND flash technology, containing no moving parts.
The outstanding reliability of the FFD 2.5” SCSI is based on M-Systems’ TrueFFS®
technology that provides full disk emulation, enhanced endurance with dynamic
wear-leveling and bad-block mapping -out flash manag ement.
Due to its unique design, the FFD 2.5” SCSI eliminates seek time, latency and other
electro-mechanical delays inherent in conventional disk drives. The FFD 2.5” SCSI
performance is 9.7 MByte/sec burst rate, 3.6 MByte/sec sustained read rate, and a
2.2 MByte/sec su stained write rate.
The FFD 2.5” SCSI is fully compatible with the SCSI-2 interface, and has the same
mechanical dimensions of traditional mechanical disks. It is a drop-in replacement for
rotating disks where top reliability is required.
Applications
FFD 2.5” SCSI provides an ideal storage solution for mission-critical applications that
must operate under harsh environmental conditions.
M-Systems' family of FFDs have been used since 1997 as mass storage solutions for
data recorders, moving maps, sonar, radar, fire control systems, black boxes, data
acquisition systems, C4ISR and rugged laptops and servers in air force, navy and army
installations worldwide.
FFD 2.5” SCSI is used in telecommunication systems within optical and ATM
switches, IP gateways, wireless base stations and core routers, providing NEBS
Level-3 compliance, top reliability and a maintenance-free solution.
FFD 2.5” SCSI top reliability and high MTBF (>1,000,000 hours) enables it to be used
in Factory Automation (FA) systems, Point Of Sales (POS) systems, assembly and
robots controllers, and within manufacturing and medical systems.
FFD 2.5” SCSI provides the most reliable solution without compromising speed,
capacity, data integrity, or portability, making it an ideal solution for demanding
applications operating under harsh environmental condition
