With such a severe slowdown, does that also mean it's going to be increasing usage of the drive and therefore shorten its lifespan?

[–] [email protected] 11 points 1 year ago (2 children)

No, it’s limited by CPU time. The drive neither knows or cares about encryption.

Some drives do, but it doesn't affect lifespan either way. Writing 10GB of encrypted data is the same as 10GB unencrypted.

Yeah, I was thinking maybe the data would be written out of order or something, but that wouldn't be the case. The data will be garbled by the encryption, but still written sequentially, or however the internal drive controller decides is best.

Isn'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.
