The first consumer terabyte SSD to offer plenty of storage, providing massive storage for mainstream users and specialized needs in data-heavy tasks and archiving.
870 QVO is Samsung’s 2nd generation high-density 4-bit MLC based SSD with the new MKX controller, comes in capacities up to 8TB, making it the world’s largest client SSD*. The predecessor 860 QVO contributed greatly to the growth of terabyte capacity sales in the SATA SSD market. Also, despite the concerns regarding 4-bit MLC SSD’s performance and quality, 860 QVO has received overwhelmingly positive feedback from customers and tech media.
870 QVO gives enhanced optimized performance and proven reliability, which makes it an ideal solution for general users who require terabyte capacity SSDs with improved everyday computing experiences.
The 870 QVO provides best in class performance as sequential read (up to 560 MB/s) and write (up to 530 MB/s) approaches the limits of performance available with the SATA interface. These improvements are accompanied by enhanced random performance, bringing up to 13% higher speeds than 860 QVO in low queue depth workloads (QD1) which makes it an ideal solution for everyday computing experiences.
With enhanced 9x layer V-NAND characteristics and a refined new controller with an advanced ECC algorithm, the 870 QVO promises to deliver worry-free endurance along with a 3-year limited warranty. The sustained performance has been enhanced up to 21% higher than the predecessor 860 QVO, allowing 870 QVO to reliably provide better performance continuously for a longer time. Also, the endurance of Intelligent TurboWrite has been enhanced to last up to 3.8 times longer.
