Okay, Thank you, Mark! Vince

Vince,

I have found by my use of hundreds of SD cards, it really doesn't matter too much which supplier you use.? I have been using non-name brand cards for years and have only had one fail because I cracked it.

You DO need to make sure you get a Class 10 card. I have been using a 32GB Class 10 card for 5 years in my Pi with zero problems.? Same card started in an old Pi 2 and now running in the latest Pi 4.? Gets used all the time, and is monitoring and storing info 24/7.?? Zero issues.? All the SD cards I make for people are Class 10 and I have not heard of any problems.

Just my 2 cents.

Mark

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

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
