Actually, if you use lists, then you can add each individual chunk of data to each list, and then use ToArray() with the DIMENSION keyword. For example:

l = list(findgen(20))
l.add, findgen(20) + 20
help, l.ToArray(DIM=1)
<Expression> FLOAT = Array[40]

This will be both the fastest way and will use the least memory.

Cheers,
