So I think I fried the SSD on my MacBook Air. I was watching a bunch of youtube videos and pushing them to my Apple TV and the fan was CRANKING for a good couple of hours. The next morning, I try to wake up the MacBook and I just get a blank grey screen. I try to hard boot it and I get the flashing folder with the question mark. I booted up into Recovery Mode and it doesn't even see the hard drive anymore. All the google search results point at a dead hard drive and one of the results pointed here showing the replacement procedure so I ordered a new drive and a toolkit as I tend to fix a lot of electronics and never had the right tools.
The repair went totally smooth. Having the right tools helped a bunch. The replacement itself probably took 5 minutes. Remove the cover, unplug the battery, swap in the new SSD and reverse steps to close up. The worst part was waiting for the OS to reinstall! Quick repair and my laptop was back up and running!
When closing up the cover, be careful with the screws as they are tiny. Make sure they're threaded in properly. I rushed a little and may have cross threaded two of them as I felt some resistance.
