@Ramhound - WD begs to differ - from wdc.com/products/internal-storage/wd-black-desktop.html "The WD Black drive featurs a dual-core processor that offers twice the processing capacity as a standard single-core processor to maximize drive performance". Also, I think WE does not make a secret of the information I'm asking, but they don't make it particularly clear either.– davidgoCommented Oct 30, 2017 at 23:07

For the fun of it I removed the controller circuit from an old WD blue drive, and it has a Marvel 88i9045 chip which I believe will be a processor.– davidgoCommented Oct 30, 2017 at 23:15

2Hard drives have had processors for a while now. You're not going to implement the fancy parts of SATA with just glue logic.– Ignacio Vazquez-AbramsCommented Oct 30, 2017 at 23:21

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
