WD Blue SN580 NVMe SSD

An efficient, cool-running PCIe 4.0 drive aimed at laptops and small-form-factor builds where thermal headroom is limited. It uses less power under load than most rivals, which translates directly into battery life in a notebook. Performance is mid-range and entirely adequate for operating systems and applications. Five-year warranty. The right choice for a laptop upgrade where heat and power matter more than peak sequential numbers.
