M-Systems makes a wide range of data storage solutions combining the unmatched reliability,   tnzo
low power consumption and speed of solid state Flash memory components
with our patented and unparalleled TrueFFS Flash management technology.

Flash memories are non-volatile and, unlike SRAM, require no batteries to retain data.
M-Systems' Flash Disks provide full disk emulation, enable cold boot, operate reliably in severe environments
and perform faster than rotating disks while consuming less power.

Quality is the most important issue to M-Systems.

The built-in firmware includes 'wear levelling', which ensures that repeated writes use different areas of the address range,
thus greatly increasing the life of the product. Please request information about this.

On PC Mother Boards

The DiskOnChip 2000 has become the standard Flash Disk module for Embedded Single Board Computers.
It is the optimal solution for boards used to control a variety of applications. It can also provide a hard disk O/S back-up for Network Servers.

Expected Life Time in year

It doesn't matter if the data is many small files or one large file, or just one sector that gets written all the time.
What counts is the total amount of data written, thanks to the wear levelling feature of the built-in firmware.
