Hi Michael,

Andy is right. From the code itself, it actually refers to MiB. It is a
typo.

Thanks,

Henry

Looks like a typo and should be MiB.  But just to be precise, MiB does
not mean million bytes.

Since this is the storage industry, which is the party responsible for
perveting the original meaning of KB, MB, etc., here are the precise
definitions:

1 KiB =3D=3D 2 ^ 10 bytes
1 MiB =3D=3D 2 ^ 20 bytes
1 GiB =3D=3D 2 ^ 30 bytes
1 TiB =3D=3D 2 ^ 40 bytes
1 PiB =3D=3D 2 ^ 50 bytes
and so on

Cheers,

a
