i'm having a hard time choosing between ssd or hdd. i have an hp envy with 1tb. but i want to buy the macbook air! but i am very confused on the difference in memory. the most i keep in my laptop would be pictures and music. i go to school but delete my work after each semester, unless i really feel like keeping it. so far I've only kept about 3 papers! please help!!!

HDD & SSD manufacturers calculate storage capacity the same way.
So 1TB equals 1,000,000,000 bytes on a SSD or a HDD.
