Samsung 860 QVO 4TB 2.5" SATA III Internal SSD

The Samsung MZ-76Q4T0B/AM is a 2.5-inch internal solid-state drive that provides 4 TB of storage through Samsung 4-bit MLC V-NAND technology. Designed for systems that use a SATA III 6 Gb/s interface, it also works with earlier SATA revisions, making it a straightforward upgrade for many laptops and desktops that accept a 7 mm drive.

With sequential read speeds that reach up to 550 MB/s and write speeds that reach up to 520 MB/s, the drive helps applications load quickly and large files move with noticeably less waiting. A Samsung MJX controller coordinates the data flow, while TRIM support keeps performance steady over time.

Data security and longevity play a central role in the 860 QVO. Hardware-based AES 256-bit encryption helps protect sensitive information without placing extra load on the CPU, and an MTBF rating of 1.5 million hours combined with 1440 TBW endurance signals dependable long-term operation.

Power efficiency matters for portable systems, and this drive draws only 3.1 W while active and just 7.0 mW in standby, which can extend battery life and reduce heat inside a compact chassis.

Whether you are a creative professional managing 4K footage, a gamer maintaining an extensive library, or a business user who wants a faster response from everyday programs, the 860 QVO’s large capacity and strong sustained performance make it a practical way to refresh existing hardware without changing the overall setup.
