SanDisk BLACK SN7100 500GB M.2 2280 PCIe Gen 4.0 SSD

The SanDisk WDS500G4X0E-00CJA0 is a 500GB NVMe solid state drive from the WD BLACK SN7100 series that installs in an M.2 2280 slot and communicates over a PCIe Gen 4.0 x4 interface. This combination gives modern desktops, gaming laptops, and handheld consoles a direct path to high-bandwidth storage without the clutter of extra cables or drive bays.

Sequential transfer rates reach up to 6,800 MB/s for reads and 5,800 MB/s for writes, so large game files, project assets, and operating-system data load with noticeably less waiting. When workloads involve many small files, the drive can handle up to 760 K random read IOPS and 1,200 K random write IOPS, which keeps browsing a large photo library or launching multiple applications feeling immediate.

The TLC 3D NAND is paired with a DRAM-less controller that lowers active and idle power draw, a detail that helps extend battery life in thin laptops and gaming handhelds. Despite the low-power design, endurance is solid at 300 TB written over the life of the drive, and a five-year limited warranty backs that rating.

Because it adheres to the common 80 mm M.2 length, the drive is a straightforward drop-in upgrade for most motherboards and portable devices. Gamers can shorten level load screens, creators can move high-resolution footage more quickly, and everyday users can give an older system a responsive, modern feel without rebuilding the entire machine.
