Silicon Motion Announces New SM2246EN SATA 6 Gb/s SSD Controller — High-Performance And Low-Power Hardware And Firmware Solution

Silicon Motion Technology Corporation, a world leader in design and production of NAND Flash controllers for solid-state storage devices, is announcing its new SM2246EN SSD controller for client solid-state drives (SSDs) and NAND-cache SSD products.  Sampling is underway of the ultra high-performance and low power consumption SM2246EN SATA revision 3.1 (6 Gb/s) SSD controller.

Independent testing results confirm that the SM2246EN’s performance and power consumption specifications place it right alongside the top SSD controllers on the market today.  In recent years, those SSD producers who do not supply their own NAND controller have usually chosen between the “Big Two” — LSI SandForce or Marvell.  Enter the Silicon Motion SM2246EN and immediate competition for the big-name players in the SSD controller arena.
