Manufacturer description

The Silicon Power 1TB A55 M.2 SSD (SU001TBSS3A55M28AB) is a SATA drive in the 2280 form factor with an M+B key edge connector, built for upgrading laptops and desktops whose M.2 slots run on the SATA bus rather than NVMe. Read the compatibility note before you order: this is not an M.2 NVMe drive, so confirm what your motherboard or laptop slot supports first. Inside, Silicon Power pairs a controller with 3D NAND flash to keep transfer speeds up across everyday workloads, and the 1TB capacity gives you room for a Windows install plus a sizeable game library or working photo and video…
