  • Connect 2.5" NVMe U.2 (SFF-8639) SSD directly to a PCIe 4-lane slot
  • Maximum performance*:
    • PCIe 3.0 4-lane - 40 Gbps
    • PCIe 2.0 4-lane  - 20 Gbps
  • Installable in standard height Desktop or Server system
  • Replace any SATA hard drive in Desktop or server equipment with a low power, shock resistant and high performance NVMe SSD
  • The 2.5" NVMe U.2 SSD can be the primary bootable device containing the OS and applications (requires support in the system BIOS)
  • Industrial operating temperature: -40 °C to + 85 °C
  • OS requirement*:



  1. For maximum performance, your system need to have PCIe 3.0 slot. 
  2. BIOS in some older system may not support NVMe Express. System with UEFI BIOS may be required. Please verify with your system manufacturer to confirm the support of NVMe Express in the PCIe slot.
  3. Software driver is required for installing 2.5" NVMe U.2 SSD. You may contact the SSD manufacturer web site to download the necessary driver for your OS
