The SSD740 measures just 7mm wide and weighs a mere 52g, offering design flexibility to manufacturers of small form-factor devices. It uses the same connector found on 2.5" SATA hard drives and is backwards compatible with the SATA II/I (3Gbps/1.5Gbps) interface.
To maximize mobile device battery life and enhance ease of use, the SSD740 supports the new SATA Device Sleep (DevSleep) feature. Developed by the Serial ATA International Organization (SATA-IO), "DevSleep defines the lowest power state for SATA technology, allowing the PHY and other circuitry to be completely powered off, unlike existing partial/slumber states, which require a partially powered PHY." Basically, in contrast to reduced power states such as standby mode, DevSleep-compatible portable devices conserve more power by shutting down the SATA interface completely and yet are able to resume working immediately when required.
To further increase the lifespan of the SSD, built-in wear-leveling and Error Correction Code (ECC) ensure reliable data transfer, while full support of the S.M.A.R.T. command helps detect possible hard drive failures before they occur.
Transcend's SATA III 6Gb/s SSD740 SSD is available in 64GB, 128GB, and 256GB capacities.
