32gb, okay
Sandisk, okay
I have had a SD card go corrupt twice in a Rapb pi. Lost all my
settings and hours later finally got the pi back online!
Thanks for the url's? 73

Hello Vince,
Not all SD cards are equal where some are faster than others,
longevity depends both on the manufacturer but also your use of
it, etc.? I would recommend the following:
?? - Don't go for anything smaller than 16GB.? SD cards are just
too inexpensive these days not to give you some extra space.?
Consider even going for 32GB now
?? - No need for industrial SD cards unless you really *must* use
an SD card.? If you really need top reliability, consider
following some? SD hardening techniques like using RAM drives and
stop logging to the SD card (which wears them out faster).
?? - Buy from a reputable reseller to avoid counterfeit SD cards
where the price is "too good to be true"
?? - I've had great luck with real Sandisk SD cards but there are
some recent articles for you to consider.? I don't recommend to go
for knock-off, no-name brands as there are bazillions of reports
of people having issues with cheap cards.? Personally, my hair is
too valuable over saving like $4.00 between a cheap card and a
main brand manufacturer.? Anyway, here are some recent URLs to
consider:
? ?? ? ? -
? ? ??? -
?????? - Older but an excellent reference -
??? - Overall, don't buy an SD card just for it's rated
performance as the various Raspberry Pi units really won't take
advantage of the higher speed cards past Class-10.? If you want
high speed I/O and/or high write endurance, buy an external USB
3.0 to SSD drive instead (you won't need an SD card at all).?
There are lots of these out there from Samsung, Seagate, Western
Digital, Kingston, etc.? If you go this route, make sure you don't
buy a cache-less drive as the performance can suffer for only
saving a few bucks.
?? - If you go with SD cards, make sure to buy a few extra SD
cards so you can play around with other Raspberry PI images and
what not
