Pros & Cons

Pros

  • ✓ PCIe Gen 4.0 speeds up to 5,150 MB/s read on the 1TB model

  • ✗ 1,200TBW endurance figure applies to 4TB, not this capacity
  • ✗ No heatsink listed, so hot M.2 slots may need your own cooling

Frequently Asked Questions

How fast is the WD Blue SN5000 1TB?

Western Digital rates this 1TB model at up to 5,150 MB/s sequential read over PCIe Gen 4.0. The 4TB model in the same line is rated up to 5,500 MB/s. Sustained write speeds are not published in the listing.

Will the SN5000 fit my laptop or motherboard?

It is an M.2 2280 NVMe drive, the 80mm length used by most desktop motherboards and many laptops. Confirm your device has an M.2 slot with NVMe (PCIe) support rather than SATA-only M.2 before buying.

Do I need a PCIe Gen 5 slot to use this drive?

No. The SN5000 is a PCIe Gen 4.0 drive and runs at full speed in a Gen 4 slot. It is backward compatible with Gen 3 slots at reduced speed, and putting it in a Gen 5 slot will not make it faster than 5,150 MB/s.

Can I move my current Windows install to this SSD?

Yes. Western Digital includes a free download of Acronis True Image for Western Digital, which clones your existing drive so you do not have to reinstall the operating system and applications from scratch.

What warranty does Western Digital offer on the SN5000?

Warranty terms are not stated in this listing. Check the current product page or Western Digital's support site for the coverage period and registration requirements that apply to model WDS100T4B0E in your region.
