Get This Deal

For just $499, down from its list price of $519.99. This is the first real cut we've seen on the DX525 in months. Its 30-day average sits at $519.61, and the 90-day average is $519.86, so this $499 price is meaningfully below both.

If you've been watching this expansion unit. This is your window.

What You're Getting

The DX525 adds five 3.5-inch or 2.5-inch SATA bays to any compatible Synology DiskStation. Setup is fast through Synology DSM, and the unit supports hot-swapping so you can swap drives without powering down.

It's backed by a 3-year limited hardware warranty.

Who This Is For

Best for: existing Synology NAS owners who have maxed out their current drive bays. If your DiskStation is full and you want to expand rather than migrate to a larger enclosure, the DX525 is the cleanest path forward.

Skip this if you don't already own a compatible Synology NAS -- this is purely an add-on, not a standalone unit.

Final Verdict

At $20.99 off, this isn't a massive discount in dollar terms, but NAS expansion hardware rarely sees any cut at all. If your storage is full and you need more bays, the price is right to pull the trigger now.
