Replacing MacBook Air's HD

My Macbook Air Mid-2013 was working perfectly until a few days ago, when it suddenly turned off. I took it to an Apple Store where we tried a bunch of different commands, but nothing worked. The technician concluded the problem was in the HD and that I would have to replace it. However, as the Mac is more than a decade old, Apple does not work or sell its pieces anymore, so I have to look for an HD from another brand, but still compatible. Does anyone have a HD brand/model to recommend for an Macbook Air Mid-2013?
