SD with 200 GB available... used from ebay... From shop, it would cost about $200, you can buy a decent USB HDD from this price and it would not have only 256 GB space but much more.
Anyway, how much space is needed to host a full node? I'm thinking about the same, using a Raspberry PI to run a full bitcoin node and I'm thinking about what size of USB HDD I need to buy.
Does SD card is a possible solution for storage, when running a node on PI? I mean the OS is writing on the swap partition continously, so SD can reach it's write limit in no time and after you can just trash your SD?

SD and SSD technologies are fairly similar in the way thy function and people run core on SSDs. Even though they're obviously more stable, they're still flash storage.
@OP, what does the SD card say on it? What brand it is, what size? The only FLASH producer I'd trust personally is Kingston (Samsung, Sony and Sandisk are alright also but not as good). Bitart, Kingston and Sandisk definitely go up to 256 gb micro sd cards (not entirely sure whether a raspberry pi is capable of supporting that in such a small and dense storage medium but...)
I've been considering using a raspberry pi also for the same operation but I always got my dependencies wrong and never had enough time to go back and correct myself from all the problems to reinstall everything.
My concern is the read/write cycles of the SD card, still.
I've found this thread, it's pretty old, but the problem is still valid:

I'm not sure about the OS of Raspberry PI but if it's a linux, then it's not a good idea to run it on an SD card or USB flash drive. Or, I only need to move the swap partition to the HDD and it will solve the read/write cycle problem. Anyway, as soon as I'll have a working system (hopefully sometime this year
) I'll make a backup copy of the SD, just in case....I have a Bitcoin full node + lightning node running stable on a Raspberry Pi3. BTC blockchain is stored in an external usb drive, swap in a pendrive. Everything works fine.
