SSDs like any other electronic devices do fail. During the last week I lost three of them, all in notebooks - two were Liteon and the other was Intel
About six months ago I lost two 1TB SSD in two Macbooks purchased together - within one week. Of course they replace these as come with a 3 year warranty.
Don't get scared by these stats, as my total device count is quite large.
Samsung, Crucial & Corsair ones appear to be more reliable - but I trust nothing. I always advise the user to use the on-line storage to backup, or to store everything on-line and work off them, which is the preferred method.
As a home user you need to backup.
