A:Answeronly if you put Music on Micro SD card or external Drive; my Rock Library has 15K songs and occupies 111GBs.
So it depends in the size of your library, for me I have 256GB flash drive to store all music on; but main storage alone probably is not sufficient.
A:AnswerThe surface pro runs windows 10. It is the operating system (and the programs/drivers loaded) that support devices like printers. Fortunately, windows and HP are friends, and all you will need to do is install the appropriate drivers/software, and the surface will be compatible.
A:AnswerYou can increase storage with Micro SD card, but this is not exactly the same as increasing on board SSD, which you cannot (reasonably) do.
On the other hand you can add a 128GB Micro SD card for about $50, 200GB for about $70 and 256GB for $150 (w/prices dropping every month).
You could also use a external SSD drive like the Samsung T3, and add 250GB for ~$100 or 500Gb for <$175 or 1TB for ~$350 this is a little bulkier but offers higher performance and greater reliability - it would be my choice if your interested in durability (and you can easily share it/take it to anther machine).
