Frequently Asked Questions
Will the SN5100 fit my laptop or desktop?
It uses the standard M.2 2280 size with an NVMe PCIe slot, which fits most laptops and desktops from the last several years. Check your manual for an "M.2 2280 PCIe/NVMe" slot before buying.
How fast is it compared with a SATA SSD?
Much faster — up to 7,100MB/s versus around 550MB/s for SATA. You will notice quicker boots, faster game loads and snappier large file transfers, making it an excellent upgrade.
Can I move my existing system across?
Yes. The SN5100 includes free Acronis True Image for Western Digital, which clones your current drive — OS, programs and files — onto the new SSD so you can be up and running without reinstalling Windows.
Is 2TB and a mainstream Gen4 drive enough for me?
For everyday computing, gaming and media the SN5100 feels very fast, and 2TB comfortably holds a large library. As a mainstream drive it is great value; for sustained heavy professional writes a high-end model would hold up better.
Singular Expert Insight
The WD Blue SN5100 is a dependable mainstream Gen4 drive: near-flagship 7,100MB/s speed, a roomy 2TB, the trust of the WD Blue name and a 5-year warranty, all at a sensible price. It is a great everyday boot-and-games drive and an easy upgrade with included cloning software. For sustained heavy professional writes a high-end drive like the Samsung 990 PRO holds up better, but for everyday gaming and general use the SN5100 feels just as quick for less.
