The stylish SD600 external SSD delivers up to 440MB/s read and write, quadrupling what you get with external hard drives. It uses new 3D TLC NAND Flash to increase reliability, with SLC and DRAM caching to handle heavy data loads. Stable and portable, the SD600 keeps up with you wherever you go with fast access to content and shorter loading times. ADATA engineers incorporate speed boosting memory caches to allows the SD600 bursts of performance when data loads are heavy and to speed up frequent tasks. DRAM cache and SLC cache (pSLC mode) make sure performance remains consistently at peak.
