Current transfer speed is bottleneck by HDD max ability.
The max HDD speed is roughly 150MB/s, which nowhere near the SATA 2 max capacity.

Sata 2 & 3 make no difference for HDD, may be applicable for SSD only.

You only get HDD, no cable, be it Sata or Sata power cable.

Not related.

Your 250GB highly is 7200 rpm or blue version (if WD)
And 1 TB mostly are green drive now, which is slower one than 7200rpm.

My green drive always goes to "sleep" one.
Wake up need 1-2 second lag, which the symptom that the forumer complain.
Has nothing to do with read, I think.
More like the HDD being idle and park its head.

The rest, you could do nothing except changing HDD (non-green drive) or change to SSD.

Apart from lowyat, outside of KL, sometimes, the availability of computer hardware is rather optionless.
Shops generally do not have many stocks or have lot of option especially for small town.
Take it or else go far far away to buy.

Huh, so fast price of HDD suddenly shoot up Rm10-20 in some computer retailers website?

When ask, most said may out of stock due to Thailand flooding.

When ask how much now, and agreed on new price, no problem to get it.

Then dismantle the external, sell off as internal, still can make extra profit...

I don't understand, how can external price remain the same, while internal one shoot up near RM100 per piece.

As most stocks available are still the old batch.

If internal price increase, so does external one.
They are using the same HDD.

Yes, I know current HDD price increase due to potential short supply, but external should follow suit as well.
How come external still remain roughly the same, while internal increase so much?

It is about expectation, speculation.
Just like currently, there is no shortage on HDD across, just some business expect/predict new supply will be disrupted and less, people start jacking up price.
And most shops current stocks are old batch and cheap one.

If 1-2 month later, Thailand flood receded and factory going to start back the production, you can see price start to soften.

Sata 2 spec is the interface of the HDD, not the ability of HDD physical write or output.
