250GB SSD enough for windows 10?

Here's one of many pieces of information on this site about SSDs. http://www.tomshardware.com/picturestory/689-best-of-computex.html

SSD is in a state of considerable flux and things change a lot. I have found Samsung and Crucial to be reliably good and have used 250 and 500Gb of both. BEST depends on purpose.

If you are gaming, and plan to put games on the SSD, I would get 500Gb. Modern games are getting very big (40GB+) Allowing for space for efficient TRIM, and putting the OS on as well, 250Gb will be used up quickly unless you are very disciplined. Larger drives tend to be faster than smaller drives.

What and why?
 
Thanks for link, I want it for the OS to make it boot faster etc, and put a couple of my most played games on it.

Im currently looking at this: http://www.amazon.co.uk/gp/product/B00P736UEU/ref=s9_simh_gw_p147_d0_i2?pf_rd_m=A3P5ROKL5A1OLE&pf_rd_s=desktop-1&pf_rd_r=1DXBARMP0KRCA00CV5BS&pf_rd_t=36701&pf_rd_p=577047927&pf_rd_i=desktop
 
That's a great fast and reliable drive. I have used both the 250 and 500Gb versions. So long as you keep only a couple of games on it, you will be fine. For efficient TRIM (Garbage collection) you do not want to fill the drive beyond 80% or so, so you get about 200Gb to use.
