usually write speed isnt that important for normal consumers as most of the time its based on the read speed that impressed us (faster boot up, faster apps loading etc)

higher write speeds is usually required when youre doing write intensive tasks which most of us dont really perform often as well. i mean, do you even perform much write as a casual consumer?

Samsung Evo have a higher write speed to compensate that they have lower endurance as the Evo is a TLC NAND which have a lower PE cycle compared to MLC NANDs like Intel, Plextor, Crucial etc etc

its to balance the SSD. i mean would you buy SSD with lower endurance if it isnt faster than MLC?
