Yes; we've been using them for years now in the products I work on. While you
can still wear them out if you beat on them hard enough, they do have good
reliability.
If you have a ready-made SD interface, these cards work nicely. If you need to
build one from scratch it gets tricky, because the interface is fairly high
speed serial (packet based) signaling, and the initialization sequence before
you can do any I/O is fairly convoluted. It is reasonably well documented in
the SD standard, but still, it takes a while to get all the code working. BTDT.
