How these alternatives compare to QNAP TR-004
Synology 4-Bay Rackmount Expansion Unit
The Synology RX418 is a rackmount expansion unit, not a standalone device. It connects to a parent Synology NAS to add four drive bays. Unlike the QNAP TR-004, it has no independent operating system or USB connectivity for direct PC attachment. You gain seamless online volume expansion within the Synology ecosystem. It fits a 12-inch rack profile with dimensions of 11.4 inches wide and 1.73 inches high. Choose this if you already own a Synology NAS and need more storage space without managing a separate unit. It lacks the hardware RAID controller found in the QNAP, relying instead on the host NAS for data protection.
G-Technology 32TB G-Speed Shuttle
The G-Technology G-Speed Shuttle uses Thunderbolt 3 instead of USB Type-C. This interface offers higher bandwidth for video editing workflows. It comes pre-configured with 32TB of storage. The QNAP TR-004 is diskless, requiring you to buy drives separately. This G-Technology unit is heavier at 16 pounds and taller at 10.5 inches. It supports hardware RAID for data redundancy. Pick this if you need maximum transfer speeds for 4K or 8K video editing. It is not suitable for users who want to build their own storage configuration or connect to a QNAP NAS. The Thunderbolt connection requires compatible ports on your computer.
QNAP 4-Bay USB-C Direct Attached Storage
This QNAP model includes 12TB of pre-configured storage in RAID 5. The original TR-004 is diskless, meaning you must purchase drives separately. Both units offer lockable drive bays and hardware RAID support. This version is ideal if you want immediate storage without the effort of drive selection and installation. It maintains the same 4-bay form factor and USB-C connectivity. Choose this if you value convenience and pre-configured data protection over custom drive capacity. It does not offer network features, keeping the focus on direct-attached storage. The black color scheme matches the original, ensuring visual consistency in your setup.
G-Technology 56TB G-Speed Shuttle Thunderbolt 3
The G-Technology 56TB Shuttle offers significantly higher capacity than the diskless QNAP. It uses Thunderbolt 3 for sustained transfer rates up to 1000MB/s. This is beneficial for high-end video editing. The QNAP TR-004 relies on USB Type-C and requires separate drive purchases. This G-Technology unit is pre-filled with 56TB of data. It is designed for professionals who need massive storage and speed without managing individual drives. It lacks the flexibility to migrate drives between different QNAP devices. Select this if your workflow demands high throughput and large pre-installed capacity. It is not suitable for users who prefer USB connectivity or modular drive upgrades.
QNAP TR-004U 4 Bay Rackmount NAS
The QNAP TR-004U is a rackmount expansion unit for QNAP NAS systems. It cannot operate as a standalone device like the TR-004. It connects to a QNAP NAS to add four SATA drive slots. The original TR-004 works with Windows, macOS, and Linux via USB-C. This unit is designed specifically for QNAP ecosystems. It fits rackmount spaces and provides additional storage capacity. Choose this if you own a QNAP NAS and need more drive bays. It does not offer independent RAID management or direct PC connectivity. It is not suitable for users who want a simple, plug-and-play external storage solution for multiple platforms.
QNAP TR-004U 4 Bay Rackmount NAS
The QNAP TL-R400S is a rackmount SATA enclosure for QNAP NAS systems. It uses SATA connections instead of USB-C. This provides reliable expansion for rack-mounted setups. The original TR-004 offers USB-C connectivity for direct attachment to computers. The TL-R400S is not suitable for standalone use. It requires a QNAP NAS to function. It adds four SATA drive slots to your existing infrastructure. Choose this if you need dedicated storage for QNAP systems without using USB. It lacks the hardware RAID controller of the TR-004. It is ideal for users who want to expand their NAS capacity within a rack environment. It does not support direct connection to non-QNAP devices.
