PU41 Quad U.2 SFF-8639 to PCIe 4.0 X16, Bifurcation Required

Add up to four 2.5" U. 2 (SFF-8639) NVMe SSDs to a single PCIe 4.0 x16 slot and use all four at the same time - an easy way to put a batch of enterprise U. 2 drives (Intel Optane 905P / P4800X, 4TB / 6TB and above) to work in a workstation or server.; PCIe 4.0 x16 delivers up to 256Gbps of total bandwidth. With no onboard bifurcation chip, there are fewer active components, less heat and fewer failure points than on switch-based cards. Backward compatible with PCIe 3.0 U.

2 enterprise drives.;
CHECK BEFORE ORDERING: this card carries no onboard switch, so your motherboard must support PCIe x16 bifurcation - enable X4X4X4X4 in BIOS. With X8X4X4 only three drives are detected; without bifurcation only Port 1 works.; Build Intel or AMD soft RAID with Windows Disk Management or Linux mdadm, and boot from a U. 2 drive after OS reinstallation and
BIOS/UEFI setup (legacy boards: data-disk use only). Intel VROC requires a separately purchased key.; No capacity limit - 4TB/6TB enterprise drives supported. New drives need initialization and formatting. Backed by GLOTRENDS lifetime technical support.
