Is the 128GB SSD prone to failing? I ask because I woke up this morning to turn on my MBA to be welcomed by a flashing folder with question mark. Booted to disk utility, couldn't even see my drive. Went to Apple Store to have it checked out and sure enough the drive failed and doesn't even register. The MBA is 2 years old, I find this to be strange seeing as it's a SSD. I've had standard drives in laptops for years with not a single failure or issue.
