Would the higher cache of hard disk enable faster downloading?

Hi, all. I wonder wether a higher cached of 8M other than 2M hard disk can
enable faster data downloading/uploading speed from internet.

No. The Internet is *slow* compared to a hard drive. The hard drive light
just flashes for an instant, maybe once a second, while downloading. So
changing the disk drive will make no difference at all to your
upload/download.

To give an example, my hard drive writes to the platters at 60MB/sec.
That is without considering the cache at all. My internet is 0.3MB/sec
via ADSL. That is 180 times slower than the disk. The cache makes no
diff at all in that scenario. Your Internet could be four time faster
than mine, and the disk is still way faster than it needs to be.

Nope. You would need a MUCH better internet connection to compare to the
harddrive transfer rate.

Wouldn't matter what was the source. You are asking about NEW content
being added to the hard drive. Do you even understand the concept of
*caching*? Caching is irrelevent on the first access of any data. It
is only useful on subsequent reaccess of that data.

Caching working on future reuse of the data, not on the first use.

It's very very very (repeat for about 10 more times) unlikely.

The speed of a download will proceed at the speed of the slowest link of the
chain between where the file currently is and where you would like it to be.

Over the internet, this is extremely (I'll save you the 'Very very' thing
this time but pretend I actually really said again it if that helps you to
understand just how extreme I think this is) unlikely to be the hard disk
transfer rate.

It isn't entirely impossible, I suppose, that your disk drive is the slowest
part of your download speed. Anything is possible but I would suspect some
kind of actual problem with software or hardware rather than a drive that is
working properly but is simply too slow.

Nothing you can realistically do with your computer will change the
speed you download from the internet. The computer is so much faster
than the internet that it doesn't make a difference.

But cached directory sectors could help.

I do agree the difference is utterly trivial, though, especially as it
will only affect the rate at which it's stored, not the rate at which
it comes in. The two processes will proceed in parallel.
