Sentence: it is a way of attacking both rotational latency and seek time

[Infin1ty]

Hi everyone,

[Infin1ty]

Could it mean that hard disk drivers with higher areal density over performance drivers with lower areal density? ( lowr latency and seek time?)

Hello Infin1ty, long time no see! That is quite the technical question you present here. I am no expert, but here's my interpretation. I am assuming you already know quite a bit about the working of a hard drive.

- Rotational latency is the delay in accessing data that occurs when the hard drive's head needs to wait for the disk to spin into the right position. The head can no sooner read the data it seeks than the disk is at the right rotational angle, because the head itself moves only in a straight line from center to edge (and reverse) along the radius of the disk, not in a circle; the movement along the circle is performed by the spinning of the disk, not by the head.

- Seek time is the time needed for the head to reach the right longitudinal (along the straight line I mentioned) position allowing it to access the right "circle" of data. I am not very sure about this, but I believe no other meaning could be gleaned from this text. In general, I believe seek time is usually more of a bottleneck than rotationla latency, because the disk spins much faster than the head can move.

Higher areal density means, as I understand from your text, that both lateral and longitudinal (horizontal and vertical) size of data blocks are decreased: it will therefore be possible for each "circle" to contain more data blocks, and the circle itself will occupy a narrower band, so that more circles may be placed together in the same longitudinal space. Hence both rotational latency and seek time are reduced.

Incidentally, the word "attacking" is a common metaphor: the delays are presented as "enemies", whom you may "attack" in order to reduce them. It simply stands for "reducing" here.

In conclusion, I agree with your interpretation, but keep in mind that I am no expert, though I don't see how this passage could be interpreted otherwise.

Hello Steven, thanks for your detailed explanation, which helps me out again as always. :) Nice to see you again! Six months have passed since your absence.

I'd say it is always somewhat jocular, I don't know whether there are many people who would use it in a serious manner, I hope not. It is quite an interesting expression, I had no idea it probably comes from Chinese! Its construction is certainly very idiomatic. Does it sound to you like the kind of construction a speaker of Chinese might come up with?

Interesting that it should be a mistake a modern Chinese could still make. Apparently Chinese hasn't changed too much since the Manchus. I happen to be a great fan of Chinese culture and history. Too bad I don't speak it at all. I once learned a few words from some Cantonese guys when they gave us a lift. Narr or something like that supposedly means sun in Cantonese.

[Infin1ty]

Nor do I speak/understand Cantonese since the offical language of China is Mandarin. : P Excuse me for my poor English please, Steven. I can't express myself well in English. :oops:
