After a quick briefing with Phison’s Michael Wu, we learned of their new SATA 3 based controller. Designed from the ground up by Phison, the PS3110 is a 32-bit quad-core 8 channel controller that supports SLC, MLC, and TLC NAND flash. It offers capacity support for up to 2TB. It also offers external DDR3L memory support from 256MB-2GB. For speed, it is capable of 540MB/s and 530 MB/s sequential read/writes and 100k/90k random read/write IOPS. Those numbers are up there with the best of the best SATA SSDs!
