Performance Redefined | Innovation Through the PCIe® Gen4 Interface
The Western Digital PC SN740 NVMe SSD resets expectations in performance through innovating with the scalable NVMe architecture bringing a new standard for what users can expect from their storage.
The Western Digital PC SN740 provides the computing customer looking for thin and longer lasting mobile devices with a solution that does not sacrifice performance and offers a range of capacities from 256GB to 2TB.
Versatility Takes a Step Forward
With PCIe Gen4x4 compatibility, the PC SN740 is designed to provide higher performance with lower power draw.
A fully integrated solution, the PC SN740 is designed with Western Digital's own inhouse controller, 3D NAND and firmware all while going through rigorous testing to provide a reliable and robust supply.
The Western Digital PC SN740 NVMe™ SSD provides performance to meet tomorrow's challenging workloads with read speeds of up to 5,150 MB/s (1TB and 2TB models) and write speeds of up to 4,900 MB/s¹ (1TB model) and endurance of up to 500 TBW (2TB model). All this comes in a small and thin but powerful form factor.
Summary
The Western Digital PC SN740 NVMe™ SSD enables manufacturers to create thin and light systems that are ready to accept the challenge of tomorrows demanding workloads with a balance of performance and power efficiency
