SLC SSD drives cost a lot more than MLC SSD drives. Are there actual differences besides cost?

SLC_versus_MLC on Wikipedia's SSD article:

Lower priced drives usually use multi-level cell (MLC) flash memory, which is slower and less reliable than single-level cell (SLC) flash memory. This can be mitigated by the internal design structure of the SSD, such as interleaving and more excess capacity for the wear-leveling algorithms to work with.
