QNAP TL-D810TC4
The desktop QNAP TL-D810TC4 provides eight SATA drive bays and a USB 4 Type-C host interface with transfer speeds up to 40Gbps. It is designed to expand storage for compatible QNAP NAS systems, Windows PCs, Macs and Ubuntu systems while supporting high-capacity data storage, backup and migration workflows.
What is the QNAP TL-D810TC4?
The TL-D810TC4 is an eight-bay desktop JBOD expansion enclosure with SATA 6Gb/s drive bays, hot-swappable trays and one USB 4 Type-C host interface. It can be configured as NAS expansion storage, an external-disk enclosure or host-managed software RAID storage, depending on the connected system.
High-Speed USB 4 Storage Expansion
Fast direct-attached storage for large-file access, backups and data movement.
The USB 4 Type-C interface supports transfer speeds up to 40Gbps, with actual performance depending on the connected device and cable. A USB 4 Type-C cable is included, and the supplied information recommends using a cable no longer than one metre.
Built-in UASP support can improve transfer efficiency and reduce waiting time when the connected computer and operating system also support UASP.
Flexible Storage for NAS, Windows, Mac and Ubuntu
Use the enclosure for managed NAS expansion, external disks or host-based software RAID.
Independent NAS Storage Pool
QNAP Storage & Snapshots Manager can create an independent storage pool on the TL-D810TC4, with support for RAID migration, disk replacement, S.M.A.R.T. monitoring and notifications.
External Disk Mode
Each installed drive can be presented as independent storage for quick transfers or short-term backup requirements.
Host-Based Software RAID
Windows, Mac and Linux hosts can use their built-in storage tools to combine drives into software RAID where supported.
Drive Access, Cooling and Physical Security
Designed for convenient day-to-day operation and drive management.
Hot-Swappable Drive Bays
Eight front-access drive bays support hot swapping for easier drive replacement and maintenance.
Lockable Trays
The included key can lock each drive tray to help prevent unintended drive removal.
Adjustable Fan Mode
A fan mode switch provides Auto, high, medium and low settings for the two 120mm cooling fans.
Host-Based Power Management
Coordinated power behaviour supports stable operation.
When the connected host powers on or off, the JBOD can synchronise its power state with the host. The supplied instructions state that the correct power-on and power-off procedures in the user manual must be followed to avoid abnormal performance.
