minus-square@emptyother@programming.devlinkfedilink6•10 months agoI did calculate it once on an older samsung drive. If you write multiple terabytes every day, you will cross samsungs estimated lifetime in 3 years. I have no idea how much data a swap partition move per day but it can’t be near that much?
minus-square@kev@lemmy.kevhomeit.tradelinkfedilink2•10 months agoBut the swap partition is only used when you run out of ram right? If I have enough ram I should not worry about that.
minus-square@Wyrryellink10•10 months agoNo, it’s used much more often. How often is determined by a value called swapiness.
