We review Transcend's latest SATA3 SSD, Ultimate series SSD740 256GB. It is powered by JMicron's JMF667H memory controller and SanDisk's 19 nm MLC NAND memory. We put it through some synthetic benchmarks, as well as real world usage tests. SSD740 supports SATA DevSleep power saving feature, TRIM commands and error correction (ECC). Transcend promises 4K random read/write speed of up to 283/267 MB/s.
