comment why does dd calculated speed uses k=1000. Is it a bug?
Nice try, but then shouldn't it print out Mb instead of MB? I have just tried default block size (512b) and it keeps using 1000*1000 as Mb. I am big time disappointed (if it makes any sense) that it uses 1000 instead of 1024. Although my tools will all of a sudden be faster, but that is NOT what I expected at all.

@ChrisInEdmonton - Chris, I got that, but since when dd uses metric version?! I remember times when 1MB of HD was '1024 * 1024'. Then WD came in, and it was '1000 * 1024'. Now dd uses '1000 * 1000'?!!!

Duh!!! I have not noticed that this is NOT a hex. I am humbled now! Thank you so much for your explanation! That is exactly what I needed!

Although your post is not a direct answer for my convoluted question (how would you know what I was thinking anyway?) I think it holds the truth for it showed me a different concept I never gave a thought. Thanks!

I am in the process of editing my question. I believe that I have a conflict of expectation and reality, and I need clarification in order to make it correct. Thanks for you time!

yes :D ... and that is why I got confused, and posted this question.

What about spin up and spin down in case of physical disk? I have noticed that if I 'flood' scsi with bunch of sequential requests in separate threads, I get much better performance (possibly due to controller sorting them out.) When I use block after block, even when sequential, it is slower because each time I have to wait for the response, and then initiate another read. I was expecting that in case of asynchronous read it is the scsi driver that will do all of that.

Np. If you have beta then maybe you should report a bug?

@VladAlexandruIonescu: I have added a few more words into my post where I think the problem occures. To me, it indicates the issue is ... id_rsa. But why?
