The Intel® SSD 750 Series should work as data drive even if the motherboard does not support UEFI* 2.3.1. Please remember that you must use a supported Operating System, the motherboard must support PCIe* Gen3 x4 and have a compatible connector (SFF-8639 or Single slot x4 connector).
Our SSD's are designed according to international standards, however, it is advised to check with the motherboard manufacturer if your system has any limitations or known issues regarding NVMe PCIe drives.
If you require further information, please let us know the motherboard brand, model and BIOS version.
For additional details, you can refer to the Intel® Solid-State Drive 750 Series Product Specification.
As noted by bidwellm, the Intel PCIe NVMe SSDs might work as secondary drives in some systems that do not meet all the recommended requirements; however, we cannot guarantee that the drive will work according to specifications.
Some systems may not be compatible with PCIe NVMe drives, so we strongly advise you to check with the computer manufacturer support if your system has any limitations or known issues regarding this type of drives.
I would like to mention that for workstation or server systems, you should look for drives of the Intel® SSD Data Center Family for PCIe*. Since they have the features required for enterprise/data center storage.
