The 520 MB/s sequential read speed of the 830 Series provides lightning-fast access to your files, loading large multimedia files in a flash and without delays. Samsung's SSDs are fully developed and manufactured in-house. The Samsung SSD 830 Series is optimized for outstanding, sustainable performance and unparalleled reliability, thanks to specially designed wear-leveling and garbage collection algorithms. Samsung's 20-nanometer class Toggle DDR NAND flash chips enable data transfer rates of up to 133 megabits per second (Mbit/s), which is more than three times faster than conventional (40 Mbit/s) single data rate (SDR) NAND flash chips. While most SSD manufacturers rely on generic dual-core controllers, Samsung has developed its own triple-core MCX controllers that excel in multitasking and ensure consistent performance over the long term. The three CPU cores are based on an ARM9 controller and can execute multiple instructions simultaneously, such as one for reading data, one for writing data, and one for optimization. With the 256 MB DRAM cache, stable read performance can be maintained even when the access area is expanded. With Samsung's Magician software, you can easily keep your SSD at peak performance, ensuring consistently good performance and reliability throughout your PC's lifespan. The Samsung SSD 830 Series comes with a user-friendly installation kit that includes a full version of Norton Ghost, an interactive installation guide, and top-notch installation tools for desktops and laptops. The Samsung SSD 830 Series features a stunning design and precise engineering—inside and out. It has a black casing with brushed metal, super slim (7 mm) for ultrabooks.
