计算机容量分为Bit.Byte.KB.MB.GB.TB.PB.EB.ZB.YB。
既然有YB这个名词出现了，应该是说有人至少具有或共有1YB的容量吧。
世界上有没有人使用1YB的硬盘，还是那只是空虚的名词。
备注:计算机容量分配一览表
Bit < Byte < KB (Kilo-byte) < MB (Mega-byte) < GB (Giga-byte) < TB (Tera-byte) < PB (Peta-byte) < EB (Exa-byte) < ZB (Zeta-byte) < YB (Yota-byte)
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
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
