LSI Corp. on Monday unveiled the third generation of its SandForce flash controller line, the industry’s most widely deployed flash management technology for driving PCIe and SATA solid state drive (SSD) and flash card solutions. The new LSI SandForce SF3700 flash controller family provides the increased levels of flash performance, reliability and endurance needed to meet the exacting needs of SSD manufacturers.

 

“From our everyday lives to the hyperscale datacenter, flash storage solutions are transforming the speed and efficiency of data storage. The SF3700 family brings a new architecture, designed from the ground up to deliver unmatched flash performance and the longevity required to drive current and future portable client computing, enterprise and big data applications,” said Huibert Verhoeven, vice president and general manager, of flash components division at LSI.  

The SF3700 family is the industry’s first flash controller that provides the flexibility to support both native PCI Express 2.0 x4 and SATA 6Gb/s host interfaces in a single device. This capability greatly simplifies SSD designs and helps to significantly reduce development and manufacturing costs for SSD makers. With the addition of the SF3700 family’s PCIe interface support, users can achieve breakthrough client performance of over 1.8GB/s sequential reads, a 3x improvement compared to Serial ATA-6Gb/s-based solutions.

SF3700 family controllers provide up to 2TB maximum capacity and a 9-channel ONFI-3/Toggle-2 flash interface. Their modular and flexible architecture enables fast migration to new host interfaces and media types, allowing for significant firmware reuse between new products, as well as continuous innovation throughout the life of the product. The result is an accelerated time to market, increased ability to support customer-specific customizations, and an extended product life for SSD manufacturers and system OEMs.

Other features and benefits of LSI SandForce SF3700 include:

“Intel is focused on providing unique offerings optimized for our customers’ specific needs. Intel expects accelerated and broader industry adoption of PCIe clients, including those with the new LSI SF3700 PCIe controller family, helping to ensure our customers have the right solution for every application,” said Rob Crooke, Intel corporate vice president and general manager for the Intel non-volatile memory solutions group.

LSI is demonstrating the new SF3700 family controllers this week at the SC13 conference in Denver, Colorado, and at LSI’s accelerating innovation summit (AIS) taking place in San Jose, California.

The AIS demo will showcase the SF3700 family’s breakthrough client performance of 1.8GB/s sequential reads using Toshiba’s second generation advanced 19nm (A19nm) NAND flash memory. LSI will also display initial reference designs, which support flash memory vendors Micron, SanDisk and Toshiba. In addition, SandForce flash controller customers Adata, Avant and Kingston will showcase SF3700-based PCIe and SATA SSD products.

SF3700 flash controllers are currently sampling to select SSD OEM customers. Volume customer shipments are expected in the first half of 2014.
