minus-squareAProfessional@lemmy.worldlinkfedilinkEnglisharrow-up11·9 months agoNo, it’s limited by CPU time. The drive neither knows or cares about encryption.
minus-squareSheeEttin@lemmy.worldlinkfedilinkEnglisharrow-up6·edit-29 months agoSome drives do, but it doesn’t affect lifespan either way. Writing 10GB of encrypted data is the same as 10GB unencrypted.
minus-squareblindsight@beehaw.orglinkfedilinkarrow-up5·9 months agoIsn’t it CPU overhead for the encryption? It needs to encrypt like 3-400 MB/s, so it seems pretty reasonable that it’s a lot slower. The drive’s lifespan shouldn’t be affected for any reason I can think of.
