QNAP TL-D810TC4 8-Bay USB4 Desktop JBOD Expansion Enclosure

Keep More Working Data Close to Your Host The TL-D810TC4 adds 8 SATA drive bays to a compatible host through a direct USB4 Type-C connection. It is designed for growing project libraries, backup destinations and larger working datasets, with a link rated up to 40Gbps. Its desktop chassis keeps expansion storage beside your workstation or supported NAS. Choose a suitable drive layout and host connection before building the storage pool. Highlights Room to Grow 8 drive bays for compatible SATA hard drives or solid-state drives. Diskless enclosure, so drive selection can match the workload. A Faster Direct Link One USB4 Type-C host interface rated up to 40Gbps. Direct connection using the supplied USB4 cable, without a hub or dock. Practical Deployment Desktop design with an internal 250W power supply. Host-based power management and selectable fan modes. Key Features Expand Storage without Replacing the Main System Connect the enclosure to an approved host and create a separate storage area for growing files or backups. On supported QNAP NAS systems, Storage & Snapshots manages the enclosure's drives and independent storage pool. This pool cannot be merged into the NAS's internal pool, and system applications remain on the NAS. USB4 Is More than a Type-C Connector A USB-C socket alone does not establish compatibility. Use a verified USB4 or supported Thunderbolt 4 connection; USB 3 and earlier ports are unsupported. Many listed NAS models require the optional QXP-40G2UC PCIe host card and, on some models, a minimum BIOS version. The host, drives, RAID layout and cable determine real transfer performance. Connect directly and use a suitable cable no longer than 1M as recommended by QNAP. Plan the Drives and RAID Together The bays accept supported 3.5-inch SATA HDDs and 2.5-inch SATA SSDs. Keep HDDs and SSDs in separate RAID groups. RAID is managed by the connected NAS or host software; this is a JBOD expansion enclosure rather than a standalone network NAS or a hardware RAID controller. Maintain an independent backup of important data. Match the Host and Software Supported QNAP deployment requires QTS 5.2.x or later, or QuTS hero 5.2.8 or later. For direct computer use, QNAP lists Windows 11 or later, macOS 12.0 or later and Ubuntu 22.04 or later with suitable host hardware. Follow the installation guide's power-on and shutdown sequence. Existing enclosure migration is restricted to supported TL USB series JBOD paths; do not assume another enclosure or operating system can adopt the disks unchanged. Keep Everyday Operation Straightforward Drive, link, status and fan indicators make the enclosure's operating state easier to check. Two cooling fans and an Auto, High, Medium or Low fan-mode selector let you choose an appropriate cooling setting for the environment. Keep ventilation clear and follow the supported operating-temperature range. Compatible Models Supported QNAP hosts include the following models. Match the exact NAS configuration, available PCIe slot, required host card, BIOS and operating-system version before ordering. These models support up to two of this enclosure under QNAP's compatibility matrix; the correct connection is required for each unit.

Choose it for desktop backup, project storage and supported NAS capacity expansion where a separate drive enclosure fits the workflow. Drives, host cards and any required mounting accessories are selected separately. Frequently Asked Questions Is this a standalone NAS?ExpandCollapse No. It connects to a supported NAS or computer. It does not provide independent Ethernet file sharing or run NAS applications on its own. Can I connect it to any USB-C port?ExpandCollapse No. Use a verified USB4 or supported Thunderbolt 4 host connection. USB 3 and earlier interfaces are unsupported, even where the connector is Type-C. Connect directly without a hub or docking station. Does my QNAP NAS need an expansion card?ExpandCollapse Many supported models require the optional QXP-40G2UC PCIe card, and some require a minimum BIOS version. Confirm the exact NAS model, free slot, card support and operating system before purchase. Can I add its disks to the existing internal NAS pool?ExpandCollapse No. QNAP treats this enclosure as an independent storage pool or external disk area. It cannot be merged with the internal NAS pool; NAS applications remain on the host. Are drives and a host card included?ExpandCollapse Drives are not included. The QXP-40G2UC host card, where required, is an optional separate purchase. A USB4 Type-C cable and drive-mounting screws are supplied. Does it add surveillance camera licences?ExpandCollapse No. It provides drive capacity to a compatible host. Camera licences, supported recording channels, surveillance applications and performance limits belong to the NAS or recording system, not the enclosure. Read more
