That unfortunately has nothing to do with the keyboard being mechanical. Many mechanical are no better then your average keyboard in that regard.
The black widow is "optimized" so the most common keys used while gaming won't block. However, there are some combination of keys where if you press 3 keys down, the 3rd key will not register.

Only on a USB keyboard that has NKRO, and supports the ps/2 adapter.
If you don't use an adapter, you still get 6 keys, which is more then enough for 99% of people.
Just remember that the board has to specifically have that feature. Most keyboards (and almost all non-mechs) are "2kro", which means they will not be able to press 3 keys at once in some cases.
