Fast way to save 2D array in c#

Question

I am trying to save a 2D array during a game in Unity. I tried to save the array to csv using using StreamWriter, and while this works, it is too slow and the game stops/crashes for a second. Is there a faster way to save the array? It does not need to be to csv, as long as I can later retrieve the array in C# I can make the conversion post-game.

Edit - More information: I am using Leap Motion to track the user's hands. I would like to save position and rotation of each hand bone (palm + 3 bones per finger) at each frame.

For Unity 2017 and later, you can try saving the data in a different thread. However, since you will do it every frame, you also need to implement a queuing system to prevent frame x+n saved before frame x if saving of frame x lags.
