Deleting Specific Dimensions of a 3D Array

Is it possible to erase specific dimensions of an array while a routine is
running to increase the performance of the routine? Lets say I have a 3D
Array:

Redim 3DArray (0 to 10000, 0 to 300, 0 to 50)

Let say I populate with three For Next Loops:

For X = 1 to 50
For Y = 1 to 300
For Z = 1 to 10000
3DArray(Z,T,X) = Rnd()
Next
Next
'Lets say I want to delete the all the data associated with X = 1 when
'the loop progresses to X = 2, and continue to do this
Next
 
T

For X = 1 to 50
For Y = 1 to 300
For Z = 1 to 10000
3DArray(Z,T,X) = Rnd()
if X > 1 then _
3DArray(Z,T,X-1) = empty ' or 0
Next
Next

Does deleting data from the 3rd dimension free up memory to speed up the
routine? Or would I have to redimension the array to see the affects on
performance?
