Superior Performance for High-End Computing: Optimized for a variety of computing applications like gaming, HD media playback, or creative software, the SanDisk X600's 3D NAND technology helps enable sequential read speeds up to 560MB/s and sequential write speeds up to 530MB/s for fast system boot-ups, quick application responses, and rapid transfer speeds. High Capacity with Enhanced Reliability: The SanDisk X600 3D NAND SATA SSD uses Western Digital 3D NAND technology not only for higher capacities (up to 2TB) than the previous generation of SanDisk X400 SSDs, but also to help reduce cell-to-cell interference for enhanced reliability. With 1.75M hours MTTF (mean time to failure), up to 500 TBW (terabytes written), and several error correction technologies, SanDisk X600 3D NAND SATA SSDs can help guard data for years to come. Enhanced Power Efficiency: Featuring an active power draw of up to 25% lower than previous generations of SanDisk X400 SSDs means you're able to work longer on-the-go before recharging your laptop.
