The SanDisk Ultra 3D is a 2.5-inch SATA III solid-state drive with 1TB of capacity, rated for sequential reads up to 560 MB/s and writes up to 520 MB/s. Its headline figure is endurance: a 400 TBW rating, high for a consumer SATA drive, backed by 3D NAND. It suits people upgrading an older laptop or desktop from a hard drive, or adding fast storage to a machine without an M.2 slot. Against SATA rivals it trades a little peak speed for durability and steady sustained writes; against NVMe drives it is far slower but far easier to fit. Owners rate it highly for reliability and easy setup.
