Frequently Asked Questions
Will the WD Blue SN5100 fit my laptop?
It uses the M.2 2280 form factor with an NVMe interface. Your laptop needs an M.2 slot that takes 80mm-long drives and supports NVMe. Shorter 2230 or 2242 slots, like those in some handhelds and ultraportables, will not fit it.
Do I need a PCIe Gen 4.0 slot to get the full speed?
Yes. The rated read speed of up to 7,100 MB/s applies to PCIe Gen 4.0 connections. Check your motherboard or laptop manual to confirm the M.2 slot's PCIe generation and NVMe support before you buy.
How do I move my files from my old drive to the SN5100?
You can download Acronis True Image for Sandisk, the manufacturer's data migration software, and use it to transfer your files to the new drive.
What warranty comes with the WD Blue SN5100 1TB?
Sandisk covers the drive with a 5-year limited warranty. Check the manufacturer's warranty page for the full terms and any usage limits.
How is the SN5100 different from the previous WD Blue NVMe drives?
The manufacturer rates the 1TB and 2TB SN5100 models at reads up to 7,100 MB/s, 30% faster than its prior generation. The drive uses Sandisk 3D CBA NAND and nCache 4.0 caching to speed up large file copies.
