SSD GOODRAM CX400 1Tb - 100% activity spikes and hult

[eewww]

Hello. Recently bought that ssd and have problem with it. For example - after i copy\paste file on same ssd disk it will spike disk activity to 100% (in task manager) few times and while this spike takes place the whole disk is "busy". I filmed short video where i copy\paste a 4 gb file on same ssd disk to show you what im talking about -
