Re: RAM manufacturers always used powers of two
Because each extra address line doubles the storage, thus inherently powers of 2. Tape, floppies and HDD have always used the approximate SI based amount based on powers of 10.
The chip makers incorrectly used K = 1024 and M = 1024 x 1024 out of convenience.
I've been buying computers & storage since RAM was 1024 bits per chip and my first floppy drive was approximately 100K bytes. It was maybe a decade or more later that public started getting confused. Really it's not a marketing plot how HDD storage is described. Now the actual random write transfer speed on a multiuser server is another story. Mostly INTERFACE speeds are quoted on the box!
