Product information

Description

The QNAP TL-D400S is a 4-bay HDD/SSD enclosure designed to expand and back up storage for QNAP NAS systems, Windows and Ubuntu computers and servers. It supports 3.5-inch SATA drives with SATA 6Gb/s lanes and connects via a supplied QXP PCIe card using SFF-8088 (or SFF-8644) high-speed cables. The enclosure supports hot-swapping and provides reliable read/write performance for storage and backup tasks.

Advantages

The TL-D400S uses a 1:1 high-speed channel design where each SATA lane connects directly to a single drive, improving transfer performance compared with shared-channel solutions. It supports multi-lane SATA 6Gb/s transfers, includes a QXP PCIe card for flexible connectivity, and can be monitored and managed from QTS/QTS hero or with QNAP JBOD Manager on Windows and Ubuntu systems. The enclosure supports software-controlled RAID configuration and records device events and notifications for health monitoring.

Suitable for

  • Expanding QNAP NAS storage capacity
  • Using as external/removable storage for NAS systems
  • Adding external storage to Windows and Ubuntu computers
  • Connecting third-party hardware RAID cards for advanced RAID protection

Key specifications

  • Model: TL-D400S
  • Drive bays: 4 × 3.5-inch SATA (supports SATA 6Gb/s)
  • Interface: SFF-8088 (or SFF-8644) via QXP PCIe card
  • Supported OS for management: QTS / QTS hero, Windows, Ubuntu
  • Hot-swappable drives: Yes
  • Product colours: Grey, Black
  • Weight: 3.43 kg
  • EAN: 4713213515952

How to use

Install the included QXP PCIe card into your QNAP NAS or a Windows/Ubuntu PC and connect the TL-D400S enclosure using an SFF-8088 (or SFF-8644) cable. Use Storage & Snapshots Manager on QTS/QTS hero to configure and manage storage pools, RAID and disk health when connected to a QNAP NAS; on Windows or Ubuntu use the QNAP JBOD Manager utility to monitor enclosure status, fan speed and firmware updates. For basic external use with Windows/Ubuntu, insert drives, set the desired RAID or single-disk mode, and format as needed (for example, exFAT for cross-platform file sharing).

Usage recommendations

For best performance and reliability, use SATA 6Gb/s drives, keep firmware and QNAP JBOD Manager up to date, and configure RAID or regular backups according to your data protection needs. When using third-party hardware RAID cards, follow the card manufacturer’s instructions for compatibility and setup.

Product comparison

Comparing the QNAP TL-D400S HDD/SSD enclosure involves evaluating a compact 4-drive desktop solution against higher-capacity and specialized alternatives from the same brand: QNAP TL-D800C, QNAP TL-D800S, QNAP TL-R400S, QNAP TL-R1200S-RP, and QNAP TL-R1200PES-RP. All compared products share support for 2.5-inch or 3.5-inch drives, Serial ATA interfaces with data transfer rates up to 6 Gbit/s, hot-swapping functionality for easy maintenance without downtime, and a stylish black and grey design. The main differences lie in the maximum number of supported storage drives, connection types, presence of auxiliary control features like an LCD display, and physical rack-mount capabilities.

⚙️ The specifications comparison table below evaluates key characteristics such as supported drive capacity, dimensions, and mounting styles to illustrate the practical significance of these differences for data storage setups.
