WD Blue SN5000 NVMe 1TB internal SSD

The WD Blue SN5000 NVMe 1TB internal SSD uses a PCIe Gen4 x4 interface to deliver sequential reads up to 5150 MB/s and writes up to 4900 MB/s. It is built for consumer workloads such as content creation, AI-assisted editing and heavy multitasking.

Compatibility checklist

Verify that your motherboard or laptop has an M.2 2280 slot keyed for PCIe Gen4 NVMe operation. Confirm the BIOS supports NVMe boot if you plan to use this drive as the OS volume. Ensure the platform can supply the active power draw of 75 mW and idle sleep power of 5 mW.

Build quality and daily implications

The single-sided M.2 2280 board fits thin laptops and compact desktops without blocking adjacent slots. Rated at 600TB written and 1750000 hours MTBF, it handles sustained creative workloads. Western Digital Dashboard software lets you monitor health, spare capacity and temperature within the 0°C to 85°C operating range.

Questions about this item

Does the WDS100T4B0E-00CNZ0 ship with a heatsink or mounting screw, or must they be purchased separately?

The drive is supplied as a bare M.2 2280 module; a motherboard mounting screw and any optional heatsink are not included and must be sourced separately.

How does the 1 TB Blue SN5000 differ from the 4 TB model in endurance and peak read speed?

The 1 TB version is rated for 600 TBW and up to 5,150 MB/s sequential read, while the 4 TB model reaches 1,200 TBW and 5,500 MB/s.

What does the 5,150 MB/s sequential read figure mean for everyday workloads on a PCIe Gen 4 system?

On a PCIe Gen 4 platform the drive can deliver up to 5,150 MB/s for large file transfers, with 4,900 MB/s write, 730,000 random read IOPS and 770,000 random write IOPS.
