QX310 v2 for NVMe SSDs
Now featuring factory-integrated DIGISTOR SSDs, the QX310 v2 brings CRU ruggedness and reliable removability to NVMe storage. For applications requiring 3.5-inch or 5.25-inch drive bays, the QX310 is perfect for high-performance NVMe removability that do not need the same level of interoperability as our SHIPS NVMe removable ecosystem..

    • Complete kits include DIGISTOR SSDs, cables, and HBAs for ease of reliable installation
    • Thousands of removal/insertion cycles (compare to tens of cycles for bare SSDs)
    • QX310 v2 smart thermal design optimizes acoustic performance
    • Enhanced signal integrity in v2 assures consistent, high performance
    • Rugged metal construction
NOTE: Use our pre-tested, factory-integrated DIGISTOR SSD modules for best performance. PCIe compliance and signal integrity depend on a variety of factors, and if for some reason you are required to choose another media option, contact us to ensure a successful implementation.

Product Description

The CRU 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 SSDs for security, transport, and backup.

The QX310 v2 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.

DIGISTOR factory-integrated storage

Note: Drive selection is an important consideration with the QX310 v2 platform and this is why we feature validated, factory-integrated DIGISTOR SSDs. 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.
