World Backup Day is a good reminder that digital files don’t last forever unless you make copies and store them safely.

With that in mind, I've found some unmissable desktop NAS deals discounted ahead of tomorrow's World Backup Day as part of Amazon's Big Spring Sale. My top choice being UGreen's DXP4800 Pro 4-Bay Desktop NAS which is down to $624 (was $780) at Amazon.

A NAS, or network attached storage system, makes backing up data far easier because it stays connected to your home or office network at all times. Instead of relying on scattered external drives, everything can be stored in one central place, with automatic backups running quietly in the background.

So, what are you getting with this NAS system?

High-speed networking is supported with both 10GbE and 2.5GbE ports offering extremely fast transfers across compatible networks. That's essential for moving large video files, backing up photo libraries, or syncing multiple devices across a household or workspace.

The NAS offers up to 144TB of storage, using four hard drives along with dual M.2 NVMe slots for caching or high-speed storage pools. It's worth noting that this model is sold diskless, so you’ll need to add your own hard drives before getting started.

Advanced software support, including Docker containers and virtual machines, let you run private apps, development tools, or smart home services directly from the system.

Local AI photo recognition runs on-device, keeping personal data private while organizing large image libraries automatically.

Security features provide peace of mind with multiple RAID options, encrypted storage through a protected vault, and detailed user permissions for shared environments.

A sturdy aluminum chassis, efficient cooling system, and tool-free drive trays help keep the system reliable while making installation and maintenance straightforward.
