PNY XLR8 CS3140 4TB M.2 2280 PCIe 4.0 x4 NVMe Internal SSD

The PNY M280CS3140-4TB-RB is a 4 TB NVMe solid-state drive designed for computers that can tap into the bandwidth of a PCIe 4.0 x4 slot. It delivers the quick response and large capacity that power users expect, making it a practical upgrade for modern desktops, workstations, or high-end laptops with an available M.2 2280 slot.

Inside, 3D NAND flash teams up with a PCIe Gen4 controller to push sequential read speeds up to 7 500 MB/s and sequential writes up to 6 850 MB/s. That level of throughput helps large game worlds load faster, lets video editors scrub through high-resolution footage without stutter, and keeps data-heavy engineering projects moving smoothly. Because the drive arrives without a heatsink, you can pair it with the cooling solution that best fits your system’s layout.

Content creators and professionals who handle sensitive data will appreciate the built-in 256-bit AES hardware encryption that secures files without dragging down performance. Reliability is supported by a two-million-hour mean time between failures rating, giving peace of mind when the drive is pushed day after day.

Installation is straightforward: slide the drive into any NVMe-ready M.2 2280 slot, secure it with a single screw, and install the latest driver or firmware recommended by your motherboard maker. To see the full speed the CS3140 can deliver, use it in a system that supports PCIe Gen4; it will still operate in older PCIe generations but at lower throughput.
