I kind of regret getting this SSD honestly. I love the speediness of it, but for paying over 100 bucks I really should have just waited another year and gotten more space. Oh well. It was an upgrade along with my CPU from the prize draw a while back.
Remember that in 2013 the price of 250GB SSDs was around about twice of what they are now (or perhaps a bit less than that, but still expensive!)
I bought my first SSD, a 128GB Crucial M4, in October 2011 for £160 ($240 USD at current exchange rates!) and I paid £135 ($200) or so for a 128GB OCZ Vertex 4 in February 2013 if that makes you feel any better.
I'd say the prices are falling faster now then they were a few years ago as you can see.
In a year those who bought 250GB SSDs this year or last year will be wishing they waited for a year and gotten 500GB ones (though I think £130 for a 500GB 850 EVO is very reasonable now - that's what Dad paid for his a month ago, but in a year they'll be under £100, mark my words).
So you know, the prices change and you can install games onto your HDD and they'll still work really well. If you want to save space on your SSD if you're running tight I recommend disabling hibernate in Windows. Saved me about 10-15GB, but honestly 50GB of free space on 120GB is pretty good!
My Surface Pro has a 64GB SSD and even with hibernate enabled on that I have 23GB free - not too bad considering I have some Adobe apps on it.
I put a 32GB SD card in it to store music and stuff like that on.
But 50GB for a game seems a bit over the top to me!
