[GRASS-user] Best Raster storage format for huge number of read only access?

Hi

I am on an OS X El Capitan.

I have done 530 simulations and each resulted in about 2600 raster maps
(all same projection, three areas).

What is the best way of storing these in a space efficient way and to
have them accessible read-only? I have them at the moment in a grass
database and thought of putting these into a squashfs which should
work, but after two days of compressing (and only having compressed
30% - slow speed presumably due to huge number of files) I gave up.

I would like to avoid having to install postgresql as I tried it before
(several years ago) and given up due to it's complexity.

I will analyse the maps in R, so any storage backend which I can use
From R and GRASS would be OK.

Any suggestions?

Rainer
