Best 250GB SSD for write speed?

Im currently trying to look for a secondary SSD for recording and rendering to. I have an average budget of around £150. Could anyone direct me to a good 250GB SSD with excellent write speeds for the price

Thanks!

Around the same speeds a little cheaper at £125

Samsung 840 Pro 256 GB, Kingston Hyper 3k 240 GB, and Sandisk Ultra Plus Extreme 256GB. The Sammy Pro is where it's at, though.
