Isso lembrame aquele mito urbano que aconteceu nas escolas de toda a gente daquela rapariga que , na aula de biologia , ao saber que o smen tem muita glicose pergunta ao professor Oh str ! Se tem tanta glicose porque que assim salgado ? <| sep |> I have OS X running on a 32 GB SSD and have around 16 GB of free space after installing the programs I need including one big one . I have a dual boot with windows and OS X and have a 100 GB exFAT partition on the windows installation . There I put all my files to mainly Dropbox to access them from both OSes . If you don ' t want to put data on it it woule be fine with 32 GB remember to calculate around 10 GB free space to be able to update . As you have a very huge SSD you don ' t have to calculate as closely as me . Calculate about 16 GB for the OS including space for updates space for your programs your data eventuallyAlso this question higly depends which OS is your main and if you install big games under Windows . To your file system question Even with your third boot option linux I would still propose exFAT . It is read writable from every single OS and has no size limitations .
