Hello everyone!

A couple weeks ago I bought an Aurora r8 with M.2-PCIe SSD 256 GB and 1TB 3.5 inch 7200 rpm SATA Hard Drive; I was wondering if i could add one third drive with 512 GB SSD (maybe u could also suggest some specs of it).

I read in some other articles that one way to add a hard drive could be to use a PCIe adapter, but is it a good solution for my computer? Is there a better solution?

Thank for your answers and sorry for my english :D
