Buffalo Memory Introduces New SATA III SSD
Everspin Technologies today announced that Buffalo Memory is introducing a new industrial SATA III SSD that incorporates Everspin’s Spin-Torque MRAM (ST-MRAM) as cache memory. In addition to breaking new ground as a SATA III SSD, this product is also the first to specify ST-MRAM for its cache. Buffalo Memory will showcase the new product at its booth (B-05) at the Embedded Technology 2013 conference held in Yokohama, Japan on November 20-22.
Buffalo’s SS6 series SATA III SSD with Everspin ST-MRAM cache improves tolerance for sudden power loss and reduces power consumption. SATA III runs up to 6.0 Gigabits per second, twice the rate of SATA II, which improves quality of service in high data rate applications.
SS6 series SATA III SSD with Everspin ST-MRAM cache improves:
- Tolerance for sudden power off
- Access time (saving some process steps which volatile memories need)
- Power consumption (MRAM doesn't require cell refresh like DRAM)
The new Buffalo SSD is designed with Everspin Technologies’ 64Mb DDR3 ST-MRAM that performs as a persistent cache, with full DDR3 speed and non-volatility. Using ST-MRAM instead of traditional DRAM has eliminated the need for a backup battery or super capacitor to power the DRAM in the event of a power failure. An ST-MRAM cache is inherently non-volatile, so it retains cached data during a power failure, and it does not require the drive to flush the cached contents to NAND flash during a power loss.
The Everspin EMD3D064M 64Mb ST-MRAM is functionally compatible with the industry standard JEDEC specification for the DDR3 interface, providing designers the ability to quickly adopt ST-MRAM in storage and embedded systems.
