SandForce unveiled SF-1000 SSD Processors
SandForce Inc., the pioneer of SSD Processors that enable commodity NAND flash deployment in enterprise and mobile computing applications, introduced its first product, the SF-1000 SSD Processor family. These highly-integrated silicon devices address the inherent endurance, reliability, and data retention issues associated with NAND flash memory, making it possible to build SSDs that deliver unprecedented performance over the life of the drive with orders-of-magnitude higher reliability than enterprise-class HDDs.
The SandForce DuraClass technology promises to accelerate mass-market SSD adoption. DuraClass technology represents a set of flash management features that work in tandem to deliver world-class SSD reliability, performance, and power efficiency that differentiate SandForce SSD Processors from standard flash controllers.
Features of DuraClass technology
- DuraWrite, which optimizes the number of program cycles to the flash effectively extending flash rated endurance by 80x or more when compared to standard controllers.
- Powerful flash media error correction (ECC) and RAISE (Redundant Array of Independent Silicon Elements), which deliver an orders-of-magnitude improvement in drive reliability versus today's SSDs and enterprise HDDs. The result is single-drive RAID-like protection and recovery from a potentially catastrophic single flash block or die failure – all while avoiding the inefficiencies of traditional RAID.
- Wear Leveling and Monitoring, which provides monitoring of flash block operational metrics to optimize wear leveling algorithms, further extending flash endurance.
- Advanced Read/Program Disturb Management, which safeguards against errant re-programming of cells during read and program cycles and unexpected power loss.
- Recycler, which intelligently performs garbage collection with the least impact on flash endurance.
The SF-1000 Family features a standard 3 Gbps SATA host interface connecting up to 512 GB of commodity NAND flash memory, and delivers 30K IOPS (random 4K read or write transfers), and 250MB/s performance (sequential 128KB read or write transfers) with 100 micro-second latency. SAS (Serial Attached SCSI) connectivity is easily achieved via a third-party SAS-SATA bridge available from multiple sources. Even more impressive, SF-1000-based SSDs can sustain peak performance for 5-year enterprise lifecycles without artificial daily usage restrictions or costly over-provisioning techniques. SandForce provides software, firmware, reference designs, and complete design kits to enable OEMs to bring SSDs to market quickly.
SSDs based on the SF-1000 Family are amongst the most eco-friendly storage drives in the world as they deliver an unprecedented 5K IOPS-per-watt for both reads and writes compared to enterprise HDDs, which deliver a mere 20 IOPS-per-watt.
"With a deep understanding of both system- and silicon-level issues, we've integrated the right balance of reliability, performance, power, cost, and time-to-market in our SSD Processors while supporting multiple flash vendors' technology," said Alex Naqvi, President and CEO of SandForce. "Our products combine key processing elements with hardware automation to efficiently address the traditional shortcomings of flash memory. This allows OEMs to provide enterprise-class SSDs to the mass-market using both SLC and lower-cost MLC flash devices while delivering peak read and write performance throughout the drive's lifecycle."
SF-1000 Enterprise and Mobile Computing SSD Processors will be available in prototype quantities later in the second quarter of 2009. SF-1000 Evaluation SSDs and reference designs in standard 2.5" drive form factors will also be available using multiple manufacturers' NAND flash memory.
