Hi as am planning for my office pc build and am confused with SSD selection does 120Gb is enough for Windows 10 pro, microsoft office, photoshop and few regular use apps strictly no games or shall I go with 240gb. And one more thing does partition can be done on an ssd if yes then how much space i need to allocate for os and rest of apps. I have a dedicated 1tb HDD for storage and I want all apps and os on ssd kindly advice.
