Prime Big Deal Day Bargains on Synology, QNAP, UGREEN, Terramaster, Seagate and More to Watch
That’s right, it’s that time once again—Amazon Prime Big Deal Day 2025 has arrived. The biggest e-retail giant in the world is rolling out its annual mega sale, and for those of us with a Prime subscription quietly siphoning cash every month, now’s the time to get something back. Whether you’re a home user looking to back up your devices or a business admin in need of robust storage solutions, Prime Day has consistently proven to be a great opportunity to upgrade your setup without breaking the bank. Unlike Black Friday—which tends to sprawl out across weeks and multiple platforms—Prime Day is a more concentrated event. That means the window to make a decision is often brief, and the best deals can vanish in hours, sometimes even minutes. So if you’re eyeing that NAS you’ve been meaning to buy or hoping to expand your RAID array with some fresh HDDs or SSDs, now’s the time to act fast. Today, we’re rounding up as many of the best Amazon Prime Day deals on NAS and storage tech as we can find. That includes offers on popular brands like Synology, QNAP, WD, Seagate, Terramaster, and others. Alongside the real-time deals that we (me and Eddie—yes, still working double shifts!) track throughout the event, we’ve also put together a list of recommended hardware to watch for. Many of these devices pop up on lightning deals with limited stock, so having a shortlist in mind can really help.
Important Note – Every year, we run these Prime Day and Black Friday deal pages the same way: by personally curating the offers we believe are genuinely worth it. If it’s not something we’d buy ourselves, we won’t include it. You can also contribute and share any bargains you come across using the community deal-sharing tool below. We do this for a couple of reasons. First, to help people make smarter decisions with their tech purchases. Second, because every time someone clicks a deal link and makes a purchase, we receive a small commission from Amazon—no extra cost to you. That affiliate income directly supports the site and allows us to keep producing NAS guides, reviews, and how-to content every single day. So, whether you’re looking to finally set up your first Plex server, expand your surveillance system, or just secure a better backup routine—there’s a good chance something will be on offer during Prime Day 2025. And if you’re unsure what’s right for your setup, don’t forget you can always use our Free Advice service for tailored recommendations.
