Agree with Solarians concerns about how games force people to buy equipment they otherwise wouldn't need and I agree with Darth_trethon 's characterization of SSDs. SSDs are really large memory sticks.
@thrudder - it might help if you stop using SSD abbreviation and start searching for a Solid State Drive. You can pick up a cheap one for 10 dollars or so and when you run out of space you can buy another cheap one and put them into a RAID. I'm seeing some nice ones in the 512G range for about 20 dollars.
I have 4 small, cheap SSDs in a RAID and I regularly back those up on my HDD (RAIDS are prone to failure).
