3D expansion to break through limits Unlike the existing planar NAND chips, 3D NAND flash is a type of flash memory in which the memory cells are stacked vertically in multiple layers. 3D NAND is developed to break through density limitations of the 2D planar NAND, and thus can deliver a greater level of performance and endurance. Perfect for your Ultrabook Compliant with M.2 form factors Type 2242 and 2280, Transcend's 3D NAND M.2 SSDs are perfect for use in Ultrabooks and lightweight notebooks. Measured at just 80mm in length, the M.2 SSD 830S makes for an easy upgrade to your computer, taking up little space while giving it a much needed energy boost. Superior transfer speeds Featuring the M.2 standard (80mm), the next generation SATA III 6Gb/s interface and a powerful controller, Transcend's M.2 SSD 830S reaches incredible read and write speeds of up to 560MB/s and 520MB/s. When used as a cache, the M.2 SSD 830S provides 1.5 times faster boot time than conventional hard drives. High IOPS to speed up loading times Dedicated to maximizing high-performance computing, the M.2 SSD 830S features 4k random file read and write speeds up to 90,000 IOPS that deliver incredibly short loading times and almost instant response for heavy graphics and multimedia applications. Store more in less space The M.2 form factor enables expansion and integration of functions onto a single form factor module solution. M.2 SSDs include a smaller form factor but with larger capacities than that of mSATA and half-slim SSDs. Potent and feature-laden Despite its extra-small dimensions, the M.2 SSD 830S boasts a DDR3 DRAM cache and contains advanced features to enhance the performance of the SSD. Error Correcting Code (ECC) Detects and corrects transfer errors to prevent data corruption Garbage Collection Relocates existing data to release memory blocks Wear-leveling Distributes data evenly across memory cells to prolong SSD's lifespan DDR3 DRAM cache Stores a temporary copy of the most active data to shorten access times DevSleep Intelligently shuts down SATA interface when not in use to prolong device's battery life SSD Scope software Transcend SSD Scope is advanced, user-friendly software that makes it easy to ensure your Transcend SSD remains healthy, and continues to run fast and error-free by determining the condition and optimizing the performance of your drive.
