Boot SSD recomendations

I will be building a new PC soon enough, now that I have a bit of money I want to grab an SSD for a windows 7 and 10 dual boot as well as productivity software and a handful of games.
I already have a 1 TB 7200 RPM and a 1.5 TB 5400 RPM which I will use for storage and backups respectively.

Any recommendations for an SSD?

Samsung EVO 850. I have one and its super quick!

How big do you think I should get it?

Biggest you can get!

I'd recommend 250GB minimum personally

mushkin (they are usa freedom company)

240GB should be enough.

The Pro is faster than the EVO but I think the EVO would be fine for most people. That's the one I'd choose anyway

Samsung 850 - whatever size you can afford.
Dead simple migration software if you need, crazy fast and reliable as hell.

Other than that Crucial mx or bx range, Intel range > the 330's. & Thats about it.

The PRO has a 10 year warranty, the EVO has 5. The PRO is a little faster than the EVO and features V-NAND tech.

Difficult decision. In the UK the PRO is an extra £30.

Got an 850 PRO myself. Very fast and that warranty.
