Many users are very confused that why real capacity is different with capacity they ordered. I collected some information and share with yours.
The disk capacity doesn't match with the actual capacity caused by the different algorithms of OS and Hard Disk.
Hard Disk manufacture caculated by 1000Byte=1KB,1000KB=1MB,1000MB=1GB:
But operation system caculated by 1024Byte=1KB, 1024KB=1MB, 1024MB=1GB.
So, the relationship between disk capacity and OS acual capcity should be :1000*1000*1000/1024/1024/1024=0.93132257461547815625
Let's take 256GB Nand flash as example, So,256GB*0.931322=238.4GB.
