If your machine is constantly writing (i.e. a heavy duty file server), you can in theory wear out an SSD quickly, especially a poorly designed SSD that has weak wear leveling algorithm.
Also in theory the firmware on SSD is a lot less stable than mechanical hard drive, so they tends to have problem more often due to design error early on.
I'd stick to a reputable brand if going for SSD for this reason.
