Manufacturer description
The KingSpec 4TB M.2 SATA SSD solves a problem most drive makers ignore: older laptops and desktops with M.2 slots that only speak SATA III, not NVMe. If your Lenovo, HP, Dell, Asus, Sony, or Acer machine lists "M.2 SATA support" in its manual, this B+M key 2280 drive drops straight in and delivers up to 560MB/s read and 540MB/s write over the SATA III 6Gb/s interface, roughly 5X the throughput of the mechanical hard drive you are replacing. Boot times shorten, browsers and Office open faster, and game loads stop dragging. At 4TB, capacity is the real headline. Few M.2 SATA drives reach this…
