How the alternatives compare to Asustor
UGREEN 4-Bay All-Flash NVMe SSD NAS
The UGREEN DXP480T Plus replaces the original’s Intel Celeron N5105 with a more powerful processor, targeting high-speed video editing workflows. It offers four M.2 NVMe slots similar to the Asustor, but lacks included drive capacity, functioning as a diskless unit. You get dual 2.5GbE ports and Wi-Fi 6E support for wireless connectivity, which the Asustor does not list. This model suits creators who already own fast NVMe SSDs and need a dedicated media server with stronger processing power than the original provides.
Asustor Lockerstor 4-Bay Hybrid NAS
The Asustor AS6704T v2 upgrades the network connectivity from dual 2.5GbE to dual 5GbE ports, offering significantly higher throughput for local transfers. It retains four drive bays and supports NVMe caching, similar to the original AS5404T. However, it uses a different processor architecture and includes 8GB of RAM compared to the original’s 4GB. This model is better for creators prioritizing raw network speed and caching performance. It is slightly larger and heavier than the original, fitting a desktop form factor while delivering enhanced performance for active media workflows.
UGREEN 4-Bay Dual 10GbE NAS
The UGREEN DXP4800 GT provides dual 10GbE ports, doubling the bandwidth available compared to the original’s 2.5GbE connections. It features an AMD Ryzen processor, offering greater processing power for demanding tasks. Like the original, it supports NVMe expansion and has four drive bays. However, it lacks the user-friendly app ecosystem, requiring manual container configuration for services like Plex. This unit is larger and heavier than the Asustor. It is ideal for users who need maximum network speed and hardware flexibility, provided you are comfortable with technical setup.
Synology 4-Bay Rackmount Expansion Unit
The Synology RX418 is not a standalone NAS but a rackmount expansion unit for existing Synology DiskStation Manager systems. It adds four drive bays to increase storage capacity, unlike the original which functions independently. It connects via a proprietary expansion cable rather than standard Ethernet ports. This unit is designed for shallow racks and provides seamless storage growth. It does not offer processing power or network management features on its own. You should choose this if you already have a Synology NAS and need additional drive space for your content creation workflow.
G-Technology 32TB G-Speed Shuttle
The G-Technology 32TB G-Speed Shuttle is a direct-attached storage device using Thunderbolt 3, not a network-attached storage system. It provides pre-configured 32TB capacity with hardware RAID, unlike the original’s empty bays. It connects directly to your computer for high-speed video editing, bypassing network limitations. This model is heavier and lacks network connectivity features like Ethernet ports. It suits professionals who prioritize data safety and raw performance over network flexibility. You would pick this if you need immediate, high-throughput access to large media files without setting up a network infrastructure.
QNAP 4-Bay USB-C Hardware RAID Enclosure
The QNAP TR-004-US is a USB-C hardware RAID enclosure, not a network-attached storage device. It supports RAID 0, 1, and 5 configurations managed via hardware, offering direct-attached storage expansion. It has four drive bays but connects via USB-C rather than Ethernet. This model serves as external backup or local capacity expansion without network management features. It is lighter and smaller than the original Asustor. You should choose this if you need a simple, high-performance external drive array for direct connection to your workstation, rather than a shared network storage solution.
