WD Green SN3000 NVMe SSD vs Samsung 9100 PRO 2TB SSD

The Samsung 9100 PRO is the faster drive by a wide margin: PCIe 5.0 with roughly triple the sequential read and write speeds of the WD Green SN3000, plus a DRAM cache, hardware encryption and a heatsink. The SanDisk WD Green SN3000 is a simpler PCIe Gen4 drive with no DRAM cache listed and no encryption, aimed at everyday consumer use. Owners rate both highly, with the Samsung slightly ahead on a much larger pool of ratings. Buy the Samsung if you move large files, edit video or game on a PCIe 5.0 board; buy the WD Green for a basic build, a secondary drive or an older system that cannot use Gen5 bandwidth.

• Choose the SanDisk WD Green SN3000 if you want a straightforward Gen4 M.2 drive for everyday storage, a laptop or desktop upgrade, or a machine without PCIe 5.0.
• Choose the Samsung 9100 PRO if you work with large video files, run AI or gaming workloads, or have a PCIe 5.0 slot and want the fastest sequential speeds plus a DRAM cache and hardware encryption.
