Overview
As the successor to the respected Indilinx Barefoot SSD processor, Barefoot 2 continues to set the standard for SATA 3Gbps solid state drive performance, stability, reliability, and low power. Barefoot 2 supports a redesigned NAND Flash controller, including enhanced ECC capabilities and support for synchronous ONFI and Toggle Mode interfaces. Barefoot 2 doubles the number of NAND channels to provide the highest random IOPS and sustained performance of any SATA 3 Gbps processor available today while maintaining extremely low power consumption.
Features
- SATA Revision 2.6 - Supports 3Gbps, and 1.5 Gbps interface speeds
- 512 GB maximum capacity
- Wide compatibility with NAND flash memory - SLC and MLC; Asynchronous, ONFI2.2, and Toggle 1.0 Mode
- High reliability - Advanced BCH ECC engine can correct up to 44 bits per 1KB
- Efficient NAND flash management - Flash Translation Layer, dynamic and static wear-leveling, and background garbage collection
- Performance consistency - No performance degradation between compressible and incompressible data
- Low Power Mobile SDR/DDR interface for user data cache and system metadata
