Yes. I found this on their site "Western Digital defines a megabyte (MB) as
1,000,000 bytes and a gigabyte (GB) as 1,000,000,000 bytes"

On the Google site I found "1 megabyte = 1 048 576 bytes"

It seems that there is no official standard for these names. However I would
suggest that unless explicitly stated, one should assume Kilo = 2^10, Mega=2^20,
Giga=2^30, Tera=2^40 for byte sizes.

Yes. Thank you.
