For example, to be able to get a Linode at only a fraction more of the cost (say, a 10% premium) with the disk being SSD (and obviously reduced capacity compared to HDD).
I have seen the current offerings but found them to either be too costly (AWS, only one of the the largest instances), or too onerous (ssdnodes.com whose base products aren't aligned with the costs elsewhere, and to move all of your hosts to be near your SSD powered database is a big task when I only seek a little task).
I was even considering co-locating as the most cost-effective way to get SSDs when providers still massively overprice them. It all feels a bit like the RAM scam a decade ago when they'd charge you near the cost of the RAM every 2 months. Again though... co-location fell into the onerous class of actions.
Right now, pragmatically I stay with HDD and Linode.
But Linode should look at my $500 per month account and be well aware that as soon as I see a competitor offer SSD nodes at a cost-competitive point that offsets the burden to move... I'll be gone.
