Wildly incorrect, there are a vast number of 64 GB SSD's in use, and 500gb drives are NOT small in any case, they are still borderline too expensive for the average consumer.
But it hardly matters, since it's well known that storage needs always exceed available capacity, and 500gb is tiny compared with with today's needs, which may be represented by a reasonable hard disk capacity of 3TB or so.
So even a 500 GB drive won't fit all of the desired 3 TB in the first place, so it's already under pressure even before Microsoft randomly decides it's ok to use up over 1% of it.
And for the much more common 64 GB SSDs, this is 10% of their total capacity.
Which means that 6 GB can never just be assumed to be so trivially small that it won't have a really negative effect on anyone.
You picked a terribly contrafactual way to be a Microsoft apologist.
