Based on the specification of this model, it doesn't support SATA III hard drives. However, most of the SATA III hard drives should be backward compatible to the SATA II specification. You may need to check with the SSD drive manufacturer.
For the memory, PC3-12800 = DDRIII 1600, it should be compatible to this motherboard. As rolli59 mentioned to you, it still depends what CPU you using.
