Oh thank god. All this time I was thinking that no storage device is 100% reliable and here you come along and shatter that view. Thank you David_Hart for assuring me that SD cards are 100% reliable and never experience data loss. I am switching to SD cards for all of my backups from now on; both at home and at work! I am sure my boss will love how much money I saved him by switching from costly tape and off site providers to simple SD cards. THANK YOU!
Don't be a tool.
No one is saying you keep your one copy of the nuclear launch codes on a SD card. He is saying they have become relatively inexpensive removable storage and that most phone makers outside of apple have acknowledged this.
