SATA III 6Gb/s SSD370

• All the speed is back and even faster. Transcend's SSD370 SATA III 6G/s SSD boasts incredibly fast transfer speeds, large capacities of up to 1TB, a compact and lightweight design, shock and vibration resistance, and supports DevSleep mode. That means you can enjoy a seamless, lag-free computing experience even when using your notebook on an extended journey.
• More space, more to store
• Besides the blazing transfer speeds, the SSD370 capacity helps you save time to drag and delete files and process large multimedia files within seconds.
• Save power, fast response
• The SSD370 maximizes notebook battery life when not in use thanks to the full support of SATA Device Sleep Mode (DevSleep). DevSleep ultra low power state conserves more battery power than current power saving features such as standby mode by shutting down the SATA interface completely. With a remarkable response time of less than 20 milliseconds, you can start working on your computer again almost instantly.
• Ultra-slim, ultra-portable
• The SSD370 features the industry-standard 2.5" form factor. Yet, it measures just 6.8mm in height and only weighs a mere 63g, which is best suited with thin-and-light notebooks, mainstream PCs, and today's advanced Ultrabooks.
• A new level of reliability
• The SSD370 offers an aggressive garbage collection and recycling system. To further increase the lifespan of the SSD370, built-in wear-leveling and Error Correction Code (ECC) ensure continued reliable data transfer. SSD Scope also includes a convenient System Clone utility to help make upgrading your existing computer to the performance boost of an SSD370 quick and easy.
• Take control with SSD Scope
• To keep your Transcend SSD running fast, clean, and error-free, the advanced SSD Scope software application is available to download and work with the SSD370. SSD Scope allows you to monitor SSD370 health status with S.M.A.R.T. technology, enable the TRIM command in the operating system to help maintain optimum write speeds, and conveniently update SSD firmware, all from a single user-friendly tool.
