> What has been your experience with reliability of SD cards for backup?

My explanation was ambiguous.  =8~|  The primary medium here is SD.  
The backup is optical. 

The oldest SD card I have was purchased about 2012.  The label was 
NextTech. Purchased via eBay from a seller in Ontario or Quebec.  It's 
been reformatted 2 or 3 times over the years and still works.  =8~)  
Recently parts of some files disappeared or showed garbled 
information. The card has served better than I expected.  Probably due 
for retirement.  =8~)

Since 2012 I've purchased three Kingston 8 GB SDs.  Two are used in 
mobile phones; one is system store in a OLPC XO 1.5.  Those SDs 
continue to work with no apparent difficulties.

General policy.  Buy only name brands: Kingston, SanDisk, Lexar & etc. 
Buy only from local businesses maintaining a reputation in the 
marketplace.  Noname cards only waste time and money. 

Regardless of reliability of a specific medium, data preservation 
comes from a good backup system.  =8~)

Regards,                            ... P.
