Write speed started fast then dropped rapidly

[andranos]

Hey guys,

I'm having problem recording my dota 2 video @ 60 fps
I'm using lagarith codec with samsung 840 evo with GTX 970
It started our with stable 60 fps but it dropped after sometime to around 20 fps-ish
I tried the write speed benchmark for 3000mb write size and it started out fast (around 480mb/s) and dropped to around 120mb/s at the end
I'm not sure whether it's dxtory problem or my SSD problem

Cheers
