ASUSTOR Drivestor 4 Pro Gen2 (AS3304T v2) – 4-bay NAS with 2.5GbE
The ASUSTOR Drivestor 4 Pro Gen2 (AS3304T v2) brings double the network performance to the affordable NAS class thanks to 2.5 Gigabit Ethernet and a modern quad-core CPU on an ARM platform with an improved iGPU for smooth 4K H.265 (10-bit) transcoding. With 2 GB DDR4, it easily handles multitasking, backups, and media streaming across the whole home.
The newly supported Btrfs file system with the Snapshot Center enables scheduled and manual snapshots for quick recovery after unwanted changes and better protection against ransomware. Tool-less installation and hot-swap support simplify capacity expansion. A rich app suite like DataSync Center, Cloud Backup Center, Web Center, Photo Gallery 3 + AiFoto 3, and Portainer opens wide possibilities from hybrid backups to hosting your own websites and containers.
The NAS is also ready for surveillance—it includes 4 free camera licenses, ONVIF support, and compatibility with 700+ camera models. Thanks to the ADM firewall, ClamAV, encryption, and options like AES-256 for MyArchive, your data stays secure. Wake on LAN/WAN ensures easy remote access and low power consumption.
