A:AnswerAre you referring to an SSD? If so, an SSD is a Solid State Drive, unlike the ones we have been using for years, a drives that has moving parts. Think of an SSD in terms of an iPhone or any other smartphone, they all use SSD dives, what is normally called "Flash Memory" and is the most reliable, stable drives made so far. If your PC has an SSD, wow, you are good for many years, no wear and tear, no defragging, no maintenance.
A:AnswerYes, you can. That's one reason I got mine - for playing movies while traveling. You can use a flash drive, the internal memory, an SD card or a USB hard drive.
A:AnswerTechnically, no. Chrome OS does not support Java, which is required to run Minecraft. There are methods of installing programs that can fix this, but it is a very complicated process. If Minecraft is a top priority for you, I recommend purchasing a PC or Mac.
