Adata LEGEND 900 PRO 4TB PCIe Gen4 x4 M.2 2280 Solid State Drive

The Adata LEGEND 900 PRO 4TB is a high-capacity internal solid-state drive designed for users who demand both generous storage space and the bandwidth advantages of the PCIe Gen4 platform. Sitting in the M.2 2280 form factor, it slots directly into any motherboard or laptop that exposes an M.2 NVMe slot with PCIe Gen4 support, making it broadly compatible with modern desktops and thin-and-light notebooks alike. With 4 terabytes of usable capacity, this drive is well suited to workloads that accumulate large volumes of data quickly — video editing project libraries, game collections, virtual-machine images, and software development environments among them. The PCIe Gen4 x4 interface delivers substantially more peak bandwidth than its PCIe Gen3 counterpart, reducing the time spent waiting on large sequential transfers and keeping creative pipelines moving. The M.2 2280 (22 mm × 80 mm) format is the most common M.2 size, so installation is straightforward: secure the drive with the single retention screw already present on most motherboards, enable NVMe in the BIOS if required, and the operating system will recognise the drive immediately. No external power cable or bracket is needed. The LEGEND 900 PRO carries Adata's PRO-tier positioning within the LEGEND lineup, placing it above the standard LEGEND 900 and targeting prosumers and enthusiasts who prioritise capacity alongside interface generation. It is sold under SKU SLEG-900P-4TCS.
