It is no surprise to me that people still have to use HDD for storage. SSD stopped getting bigger a decade plus ago.
SSD sizes are still only equal to the HDD sizes available and common in 2010 (a couple TB~). SSD size increases (availability+price decreases) for consumers form factors have entirely stopped. There is no more progress for SSD because quad level cells are as far as the charge trap tech can be pushed and most people no longer own computers. They have tablets or phones or if they have a laptop it has 256GB of storage and everything is done in the cloud or with an octopus of (small) externals.
I bought 4x (1TB->4TB the storage for half the price after my SSD died after 5 years (thanks samsung), what you mean they 'stopped being bigger'?
Sure, there is some limitation in format, can only shove so many chips on M.2, but you can get U.2 ones that are bigger than biggest HDD (tho price is pretty eye-watering)
SSDs did not "stop getting bigger a decade plus ago." The largest SSD announced in 2015 was 16TB. You can get 128-256TB SSDs today.
You can buy 16-32TB consumer SSDs on NewEgg today. Or 8TB in M.2 form factor. In 2015, the largest M.2 SSDs were like 1TB. That's merely a decade. At a decade "plus," SSDs were tiny as recently as 15 years ago.
