Synology Plus Series HDD 4TB | 3.5" SATA 5400RPM NAS Drive – 3-Year Warranty

Your Synology NAS is running on a drive that's about to quit, or you're building one from scratch and need the right platter in there. This is the 4TB Plus Series drive Synology actually backs for sustained NAS workloads.

One thing before you pull the trigger: your DSM version needs to be at least 7.1.1-update 4. Check Settings > Update & Restore first. If it's below that, update, then install.

Fits across 25, 23, 22, 21, 20, 19, and 18 series models, plus the RX418, DX1222, and DX517 expansion units. Full supported-model list is in the specs below.

Three-year limited warranty. If something's off down the track, you log a Synology ticket – not ours. Know that before you buy.
