Marvell Unveils Its Third-Generation SSD Controller

Marvell today announced the 88SS9187 SATA controller, the successor of the 88SS9174, which was used in many drives including Crucial's m4 and Intel's SSD 510.

The 88SS9187 features a 6 gigabit-per-second (Gb/s) SATA Revision 3.1 compliant host interface optimized for the solid state drive sector. MArvell says a significant number of high-profile SSD manufacturers are set to deploy Marvell's newest solution immediately, with additional partners expected to integrate 88SS9187 implementations later this year.

Marvell?s newest SSD controller boasts an open, architecture that supports NAND Flash interface up to 200MB/s per channel. The 88SS9187 also offers a correction capability thanks to its ECC engine with Adaptive Read and Write Scheme and on-chip RAID functionality.

Performance figures include ~500MB/s of sequential write performance even at dirty drive conditions as well as "best-in-class" random read and write IOPS with "minimum over-provisioning" and "minimal performance degradation", according to Marvell.

The device also features low active and stand-by power consumption rates, meeting the requirements of the demanding Ultrabook computer market.

Other features of Marvell's third-generation SATA 6 Gb/s SSD controller include:

- Supports on-chip RAID technology for the NAND device with flexible firmware based algorithm to optimize retiring of defective NAND block, plane, die or device.

- Supports high-speed DDR3 DRAM interface with support for up to 1 G byte memory that permits implementation of performance optimized mapping algorithms.

- Maximum sequential read performance for a SATA 6G device.
