(bit).Byte (B).KiloByte (KB).MegaByte (MB).GigaByte (GB).TeraByte (TB).PetaByte (PB).ExaByte (EB).ZetaByte (ZB).YottaByte (YB).NonaByte (NB).DoggaByte (DB)
1 Byte = 8 Bit
1 KB = 1,024 Bytes
1 MB = 1,024 KB = 1,048,576 Bytes
1 GB = 1,024 MB = 1,048,576 KB = 1,073,741,824 Bytes
1 TB = 1,024 GB = 1,048,576 MB = 1,073,741,824 KB = 1,099,511,627,776 Bytes
1 PB = 1,024 TB = 1,048,576 GB =1,125,899,906,842,624 Bytes （13107.2个80G的
1 EB = 1,024 PB = 1,048,576 TB = 1,152,921,504,606,846,976 Bytes
1 ZB = 1,024 EB = 1,180,591,620,717,411,303,424 Bytes
1 YB = 1,024 ZB = 1,208,925,819,614,629,174,706,176 Bytes
1 DB = 1,024 YB＝ 1,237,940,039,285,380,274,899,124,224 Bytes
1 NB = 1,024 DB＝ 1,267,650,600,228,229,401,496,703,205,376 Bytes
现在了解1NB的概念了吧，人类发展这么多年才到TB、PB储存时代，不知道世界毁灭前，能不能发展到NB时代。
