500GB PCIe 4.0 NVMe SSD

The SanDisk WD Blue SN5100 is a 500GB internal solid-state drive built for consumer workloads. It uses 3D NAND flash and connects through an M.2 2280 slot with a PCI-Express 4.0 x4 interface. The drive operates without a DRAM cache and relies on host memory buffer technology.

Build integration and thermal headroom

The single-sided M.2 2280 form factor measures 2.38mm in height and fits standard motherboard slots without a heatsink. PCIe 4.0 x4 bandwidth frees up SATA ports for additional storage devices. Operating temperatures range from 0ºC to 85ºC while non-operating limits extend from -40ºC to 85ºC.

Capacity and sustained performance

Sequential reads reach up to 6600 MBps and writes up to 5600 MBps for large file transfers. The 500GB capacity suits operating systems, applications and active project folders. nCache 4.0 technology maintains write speeds during extended copies. Shock resistance is rated at 1500G and vibration tolerance at 5 gRMS during operation.

Questions about this item

What limits the WD Blue SN5100 500GB under sustained write workloads?

The drive has no DRAM cache and relies on host memory buffer, so long sequential writes drop to the native NAND speed once the SLC cache fills.

How hot does the 500GB SN5100 run when it is working all day?

It is rated for 0 °C to 85 °C operating temperature and ships without a heatsink, so case airflow determines actual temperature.

Which M.2 slot key and length does the 500GB SN5100 need?

It uses an M.2 2280 form factor with a PCIe 4.0 x4 NVMe interface, so the motherboard must provide an M-key slot wired for PCIe.
