Data storage hit hard (3)
I believe the answer is:
ram
This could be a double definition.
'data storage' is the first definition.
'RAM' can be an answer for 'storage' (RAM is an example). I am not certain of the 'data' bit.
'hit hard' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for ram that I've seen before include "Prepare to raid" , "Crash into like male sheep" , "Computer memory of a sheep?" , "farm animal" , "Tamp" .)
