    Vszerda PU21 Dual U.2 SFF-8639 SSD to PCIe 3.0 X8, Bifurcation Required | 2x U.2 SFF-8639 on One X8 Slot, 64Gbps Combined, Enterprise Drives 4T/6T+, CHECK: Bifurcation X4X4 Required, RAID 0/1

    Be the first to review this product...
    • Add up to two 2.5" U.2 (SFF-8639) NVMe SSDs to a single PCIe 3.0 x8 slot and run both at the same time - a clean way to put a pair of enterprise U.2 drives to work in a workstation, NAS build or home server.
    • CHECK BEFORE ORDERING: this card carries no onboard switch, so your motherboard must support PCIe x8 bifurcation - enable X4X4 in BIOS. Without bifurcation only one drive is detected. Not compatible with Mac Pro.
    • PCIe 3.0 x8 delivers up to 64Gbps of total bandwidth shared by both drives. With no onboard switch chip there are fewer active components, less heat and fewer failure points than on switch-based cards. Fully backward compatible with PCIe 2.0 U.2 drives.
    • Build RAID 0 / RAID 1 across the two drives with Windows Disk Management or Linux mdadm, and boot from a U.2 drive after reinstalling the OS and setting BIOS/UEFI (some legacy boards support data-disk use only).
    • Rated for enterprise-class U.2 SSDs with no capacity limit (4TB/6TB and above). New drives need initialization and formatting. Backed by GLOTRENDS lifetime technical support.

    GLOTRENDS PU21 Dual U.2 SFF-8639 SSD to PCIe 3.0 X8 Adapter, Bifurcation Required Two enterprise U.2 SSDs, one PCIe slot, zero switch chips. The PU21 passes each 2.5" U.2 (SFF-8639) NVMe SSD straight through to the PCIe 3.0 x8 lanes - fewer active components, less heat, fewer failure points, and no switch-chip price tag. IMPORTANT - READ BEFORE ORDERING This is a passive adapter. Your motherboard must support PCIe x8 bifurcation - enable X4X4 (or Hyper M.2 X16) mode in BIOS. Without bifurcation only one drive is detected. Not compatible with Mac Pro. Check your motherboard manual or message us before ordering. WHAT YOU GET 2 x U.2 (SFF-8639) ports for enterprise NVMe SSDs, no capacity limit (4TB/6TB+) Up to 64Gbps combined bandwidth, backward compatible with PCIe 2.0 Passive design: no fan, no noise, no extra power cable RAID 0 / RAID 1 via Windows Disk Management or Linux mdadm Bootable from a U.2 drive (OS reinstallation + BIOS/UEFI setup)
