7WF74 Dell 512GB PCI E NVMe 4.0 x4 Solid State Drive (SSD)
7WF74 Overview
The Dell 7WF74 512GB PCI Express NVMe 4.0 x4 M.2 2280 Solid State Drive (SSD) is a high-speed internal storage solution designed to dramatically improve system responsiveness and data transfer performance in compatible laptops, desktops, and workstations. It uses the PCIe 4.0 x4 interface with NVMe protocol, which provides substantially faster sequential read and write speeds—in many cases up to around 6000 MB/s read and 4000 MB/s write, depending on the host system and workload—compared with older SATA or PCIe 3.0 drives, resulting in quicker boot times, faster app loading, and smoother large file handling.
Built in the standard M.2 2280 form factor.
