SanDisk Blue SN580 250GB M.2 2280 PCIe Gen4 x4 Internal SSD

The SanDisk WDS250G3B0E-00CHF0 is a 250GB NVMe solid state drive that fits the M.2 2280 slot of many current desktops and notebooks. It connects through a PCIe Gen4 x4 interface, giving the drive a direct, high-bandwidth path to the CPU for faster data movement than older SATA models.

Sequential read speeds reach up to 4000 MB/s and write speeds reach up to 2000 MB/s, so applications load quickly and large files transfer with minimal waiting. The drive relies on TLC NAND that works with Western Digital nCache 4.0 technology, which adds an extra layer of dynamic SLC caching for short, intense bursts such as copying project folders or launching demanding games. Random performance of up to 240,000 IOPS for reads and 470,000 IOPS for writes helps maintain system responsiveness during multitasking or while using creative software that shuffles many small files.

The slim M.2 card sits directly on the motherboard, removing the need for drive cables and making it useful for small form factor systems or thin laptops that need to save space. A low-power architecture helps reduce energy draw, which can translate into longer battery life when you work away from an outlet.

With a 150 TBW endurance rating and a five-year limited warranty, the drive is built for everyday computing workloads such as office productivity, web browsing, photo management, and light video editing. It also serves well as a dedicated boot drive in a gaming rig, leaving larger capacity drives to handle bulk storage.
