This will be the main and only drive in my laptop as I'll be selling the hdd and moving the Kingston a2000 to my desktop as a game drive for those games i frequently use. The Samsung 980 is dram less. Performance figures are 3,100 and 2,600 MB/s for the 980 and 3,500 and 2,500 MB/s for the Kingston Kc2500. Both are 300tbw and I also think they both have 5 years warranty. Are there any problems with either of them? Both are good enough and better than my current a2000 so pick whichever one is cheaper?
