In the computer newspaper, the Dutch bank's 20 data centers have about 7PB of disk and more than 20PB of tape storage, and the annual growth of 50%~70% reserves,

So want to see how much PB, calculate 27pb about 400,000 80 of the hard disk size.

1Byte = 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 x 80G
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
