I have a lot of files I like to take on the go, so that is why I just bought a 2TB Seagate M9T SATA drive for my macbook pro. At just $99 (price of the seagate backup plus to get the bare drive), it is a fraction of the cost of getting a 512GB SSD for $500. Is the price for less storage worth it that much? 5 times the price for 1/4 of the storage. What is your preference, storage or speed? In this example, would you rather get a 2TB internal SATA drive or 512GB SSD in your macbook pro? If you have SSD, how do you manage with the smaller storage availability?
