Don't ignore these SSD failure signs.

Yes, SSDs fail, and MacBook Airs are not immune.

The main red flags: your MacBook freezes or kernel panics out of nowhere, especially when reading/writing files. Apps hang or crash randomly. Files get corrupted or won’t open. And boot times go from fast to painfully slow. If you run Disk Utility and see “S.M.A.R.T. status: failing” — that’s not a suggestion, that’s a countdown.

Proactive backup is simple: set up Time Machine to an external drive and leave it plugged in or connect it weekly. For extra peace of mind, add a cloud backup like Backblaze or iCloud Drive for critical files. If the SSD dies, you swap it and restore from backup. If you don’t have a backup, you lose everything.

The real trick is not waiting until you see these signs. Run a backup right now. Future You will be grateful.
