Flash memory cells have a certain number of times they can be written on before they die. With average usage for the 250gb evo this is estimated at like 20+ years. Recording won't slow things down, lag or hurt its performance, that mostly only applies to hdds as they only have 1 head to read/write from 1 location and could cause lower fps having to jump around reading files that are running and recording at the same time, not to mention hitting the bandwidth limit. Ssds can read/write at multiple places at once and of course is faster as well. Depending on the codec and res of the recordings, your hdd may be fast enough but if it's not then use the ssd.
Thank you so much! So if I do record to my main drive, no side effects should occur? I was just wondering if recording at the same drive would make things load slower (such as games) while recording, because it's reading and writing at the same time, and the everything is on it, like the OS, games, recording software ect.
