A lot of them nowadays have "load balancing" code in the hardware. If it notices a hot spot, it reorganises the data to avoid that hot spot. Cheaper ones, probably done. I have a 256 Mb From Crucial which I wrote about many years ago in QL Toady - around 2002 or 2003, it still works and is in use daily. I continually read and rewrite it. It is my own "QL On a Stick with QPC" and two hard drives, plus it contans my subversion repositories for my QL Toady articles, my work on Firebird Database Docs, programming projects and so on. It also gets quite well hammered as a general purpose "floppy disc" as I copy stuff from my laptop to my desktop using it, and delete the files afterwards. So, buy your cards from a reputable source, pay a little extra for them, and you should be fine. I recommend http://www.crucial.com/uk - service is excellent and quaility is likewise, excellent.
