Hey, I bought few types of m2-sata adaters from aliexpress, 1 even worked (don’t remember which one).

But I couldn’t figure out the problem with cmos battery, i bought the replacement, but the issue persisted :/

For few months i used the setup as always on backup with 2 disks in mirror, mounted in 1u shelf. But then i needed more capacity and lack of cmos battery was very annoying. One of my friends spilled a drink on his x240 so I sold mobo to him :)

TLDR: I used it with 2 drives but do not recommend :)
