Product Description

CRU’s Data Express® QX310 v2 blends our heritage of removable drive ruggedness with the extraordinary performance of PCIe SSDs. The QX310 v2 provides dependable removability for PCIe/NVMe drives for security, transport, and backup.

The QX310 v2 frame and carrier is ideal for small form factor applications, maximizing the use of space in small PCs, mobile systems, surveillance, and unused full-sized bays.

Mounted in either 5.25” or 3.5” drive bays found in many desktops and workstations, the simple design of this enclosure makes swapping M.2 or U.2 storage easy.

The QX310 v2 metal frame and drive carrier, along with its fan, are designed for maximum airflow and heat dissipation, protecting your data and reducing the chance of data speed throttling.

The QX310 v2 removable drive provides years of reliable performance while protecting data at the full speed and potential of your system. CRU offers a 3-year warranty and phone support to ensure your QX310 v2 meets your needs.

Note: Drive selection is an important consideration with the QX310 v2 platform. While most NVMe drives are compliant with PCIe specifications when installed on a computer's motherboard, the additional cabling and connections that comprise the QX310 v2 removable drive system may cause some models to fall outside the margins of compliance.

PCIe performance depends on the specific combination of QX310 v2, host bus adapter card, cabling, and the drive model. A third-party laboratory has verified that the following drive models are fully compliant with PCIe specifications when used with QX310 v2 and bundled host attachment accessories:

Samsung MZVLB1T0B (M.2)
Toshiba THNSN5256GVU7 (M.2)
OCZ Z-Drive 6000 ZD605M020-0800G (U.2)

Successful functional testing has also been performed on more than a dozen other drive models, but they've not been formally tested in a third-party lab.

Included Items

  • Screws for installation
  • Set of 3 keys
