TEAMGROUP QX Series 4TB SATA III 2.5-Inch Internal SSD

The TEAMGROUP QX Series 4TB targets a specific buyer: someone who values capacity and compatibility over bleeding-edge speed. It is a 2.5-inch SATA III drive with a 7mm thickness, the same footprint used by nearly every laptop hard drive and desktop 2.5-inch bay for the past decade. That makes it a natural fit for breathing new life into an aging notebook, building out a budget desktop, or swapping the sluggish mechanical drive in a PlayStation 4. With 4TB on tap, storage anxiety largely disappears.

Performance sits at 560MB/s read and 500MB/s write, figures that reflect the practical ceiling of the SATA interface rather than a limitation of the drive itself. The capacity comes from QLC NAND, a technology that packs more data per cell to keep large drives affordable. Construction follows the familiar 7mm 2.5-inch standard, so installation is a matter of connecting the SATA power and data cables. One practical note: the drive arrives unformatted and will not appear to your OS until you initialize it, a step TEAMGROUP documents on the product page. The warranty, handled by TEAM Japan Corporation, replaces units that fail naturally under normal use, but does not extend to any data stored on the drive.
