Looking to use some sort of non-volatile memory for data logging. There are options
like flash memory chip, SD flash card and battery backed SRAM etc....
I have never used flash memory before, so the question is this:
1. When using flash memory i have been told they can "wear" out. Since i am logging lots
of data (samples at every 500ms) i am bit worried about the wear out factor. I am also
told that for lots of writing to flash you need a data spreading algorithm etc etc. What are
the thoughts around this?
2. Using battery backed SRAM has the advantage of zero wait states on write and unlimited
endurance....better idea? (Microchip makes a 1Mbit 8 pin device)
Bit stuck in a decision paralysis about this

Any comments/help on this?
Thanx
