The KC600 is equipped with the latest 3D TLC NAND technology while supporting a complete security suite with AES hardware-based 256-bit encryption, TCG Opal and eDrive. The disk has read and write speeds of up to 550/520 MB / s * for efficient storage of up to 2 TB ** data. It is available in bundled kits containing everything you need for a simple and convenient installation and upgrading of desktops and laptops.* Based on "installation-ready performance" with a SATA 3.0 motherboard. The speed may vary depending on the host's hardware and software as well as usage. IOMETER's random 4K read and write test is based on an 8 GB partition.*** Some of the specified capacity is used for formatting and other functions and the actual available capacity for data storage is therefore slightly smaller than indicated on the products.
