Use a USB Stick to Boot Into Windows Boot Camp and Save Space on Mac
Many Mac owners run Windows in Boot Camp, but if you want to save space (like a Macbook with limited memory) and make Windows run faster, try a USB SSD.
Traditional external spinning drives will be too slow to use, says Cult of Mac, but the Pocket SSD is fast – and fast. Getting OS and Boot Camp drivers on an SSD takes a long process, and these drives can be expensive (the 120GB shown here is $ 100, and the 240GB version is $ 175), but you can run Windows without it and also use it for expanding your storage space.
