There are many reviews around the web claiming that SSDs are much faster than HDDs (tomshardware, notebookcheck, technize) . Nowadays I see more and more HDs that have SATA3 interface, which allegedly has twice the throughput of SATA2. But if hard drives are slower than SATA2 SSDs then why to use SATA3 in hard drives at all? Clearly HDs don't utilize even SATA2. The only reason I could think of is that maybe HDs, once in a while, have bursts that use more than SATA2 can give but in average still have low throughput. Is it so or are there other reasons?
Update: Found a different question with an answer that probably answers my question.
2It's outrageous that this question is closed as subjective. I'm afraid, Diago, you didn't understand the question. It isn't talking about brands or matters of taste. It is about two generations of the same technology and whether the newer generation could actually be utilized by the existing products. What's subjective about that? – FireAphis – 2010-11-22T11:16:24.983
@FireAphis. Please review the FAQ. It's a discussion which does not fit in with the Q&A format of Super User. You asking users to give reasons as to why one is a better technology then another. This is NOT a discussion forum. It's a Q&A site. I would suggest you review the FAQ about what is or isn't allowed. – BinaryMisfit – 2010-11-22T12:10:29.957
1@Diago I have to disagree. The question is clearly asking WHY one technology is being used with another. NOT, which is better. My answer has NOTHING to do with which is better. I state it is strictly an economic consideration. – Everett – 2010-11-22T15:58:35.810
1I'm asking why one technology is used with the other when there are no apparent (to me) reasons for that. Moreover, asking why one technology is better than other isn't necessarily subjective. For example, there is a wide consensus that SATA was an improvement over IDE. Why isn't it legitimate to ask why is it considered an improvement? – FireAphis – 2010-11-22T19:01:25.437

@JYelton I suggest all of you take some time to review the FAQ. This is a discussion. Super User is an Q&A site. If you want to discuss something, take it to chat, if you want to ask a question, within the scope of the FAQ, then read it, understand it and apply it. There is reasons why Super User is strongly moderated.
