Check out the new line of 2.5-inch SATA III SSDs from Kingmax Technology. These can be had in four different storage capacities: 64GB, 128GB, 256GB and 512GB and are equipped with an impact-resistant metal shell, a SATA III 6.0 Gbps interface, NCQ and TRIM support and a MTBF of 1.2 million hours. These SSDs mean business.
They offer read/write speeds of up to 415/95 MB/s (for the 64GB model), 415/175 MB/s (for the 128GB model), 415/260 MB/s (for the 256GB model) and 415/260 MB/s (for the 512GB model). Nothing yet on pricing though.
