M-Systems develops, manufactures and markets innovative data storage solutions based on flash memory for markets, such as mobile phones, PDAs, set-top boxes, embedded systems, military/rugged applications, PCs and laptops. They have secured a list of design wins that is impressive both in quantity and quality. In addition to their OEM partners, they have strong strategic partnerships with leading flash suppliers, such as Toshiba, Samsung and AMD. The family of flash-based data storage products includes both removable and on-board storage solutions in a wide range of capacities, interfaces, form factors and technologies.
Today we will be taking a look at M-systems Fast Flash Disk (FFD) in the Sata format, before we move on let me explain a few things about the technology.
M-Systems' Fast Flash Disk (FFD) 2.5" Serial ATA Flash Disk is a state-of-the-art solid-state disk, based on NAND flash technology, that provides the functionality of a hard disk with no moving parts. FFD 2.5" Serial ATA Flash Disk is an ideal, reliable storage solution for telecommunication and blade servers industry that must support 99.999% availability and comply with NEBS Level 3.
FFD 2.5" Serial ATA Flash Disk delivers outstanding reliability and enhanced endurance thanks to M-Systems' TrueFFS® technology, which applies dynamic wear-leveling and bad block management. Due to its unique design, FFD 2.5" Serial ATA Flash Disk provides high-performance sustained read and write rates up to 150MB/s and supports Serial ATA 1.0a standard.
FFD 2.5" Serial ATA Flash Disk is fully compatible with the SATA 1.0a interface, and has the same mechanical dimensions and mounting holes of traditional mechanical disks. It is a true drop-in replacement for rotating 2.5" Serial ATA (SATA) and Serial Attached SCSI (SAS) disks with highest reliability and operating MTBF hours.
M-Systems' family of FFDs has been providing rugged, mass storage solutions to an expansive range of industries since 1997. In air force, navy and army installations, it has been field-tested inside data recorders, moving maps, sonar, radar, fire control systems, black boxes, data acquisition systems, C4ISR, telemetry systems, rugged laptops and servers.
So you may ask why are we looking at a flash based HDD or FDD (solid state) as its better known, the answer is pretty simple… in-car pc’s and access times so fast they are measured in milliseconds(and quite a number of email requests) Put it this way, yes you can fit a normal disk with some kind of protection and in most cases that would be ok. But what if you drive a sports car or have had sports shocks and springs fitted, it doesn’t matter about the protection on a HDD you could have. Eventually the HDD will fail and when it does it could be a costly affair replacing one all the time and i am talking from experiance.
Step in the M-Systems FDD, and as it is flash based there is no mechanical parts to get vibration and impact that a firm suspension would give and thus providing a reliable disk for which you were able to run an operating system from. The question we want to find out is how fast are the access times and how far the technology has come, shall we get on with the review.
