Hy guys,

I’m looking to purchase a 4TB IronWolf Pro HDD, but I found two different versions of that drive. Some stores sell it with 126MB cache and some with 256MB but I can’t find the difference even by reading the datasheets (aside from the cache).

What is the difference? Are they different revisions of the same unit? Is the 256MB one newer?

Thank you

    HDD cache hardly matters these days. Latency sensitive stuff should be stored on SSDs or cached within system RAM. It is only relevant in edge cases.

    If anything more cache can be a bad indicator as HDDs with a lot of it tend to be SMR drives. However, all Ironwolf (Pro) drives should be CMR.
