It depends. I have multigig PostgreSQL DB on Orange Pi 2 and a consumer sandisk uSD, that I scrape hundreds of news articles to daily (incl. images), for several years. No issue, yet. Fsync and PostgreSQL checksumming enabled, of course. The same goes for the other Orange Pi PC I have, where I write weather data in 5 minute intervals for several years. No issue either. I have a very good power distribution (custom made cables, high quality 40A/5V power supply), which makes a big difference in reliability, overall. My Raspberry Pi has uSD card issues every 3rd boot (probably gets into a read-only mode). I have to boot it multiple times to get the uSD card to work. It uses Rpi branded power adapter. Also, for years (~7) I used a single 16G SD card for all my camcoder recordings. It has to had handled >1TB and it still works. I really can't complain about any of my (u)SD cards. (I run a cluster of 11 boards and I had one uSD card failure over 3 years. And it was some cheap "Samsung" from aliexpress. Verified Sandisk A1 cards never failed me so far.)
