I agree 37% isn't sparse. Were you to briefly jump around through the
data with an editor you'd probably conclude the data is sparse. I
finally measured.
Anyway, sending the output to a file was quick, and I haven't raised any
red flags that amends were not in place. Since the data has form
T[0-9]+ I can do away with the index table and store the integer directly.

Have you tried stored data as a vector and the linear index of the item
into another vector?
Final step would be fill in data into a sparse vector and then reshape it
into rank 2.
However 37% filled is not that sparse , IMO sparse meant at most a few
percent filled. Use of sparse array for 37% is overkill. What you
needed is
more physical RAM.
