Sata I (1.5Gb/s) or Sata II (3.0Gbb/s) make no difference one actually, HDD capability itself never able to fill up the 1.5Gb/s aka the speed is capped by the HDD output itself, not the Sata interface.

So Sata I HDD may faster than Sata II one.

LOL,

Actually don't care much about Sata I,II,III for ordinary HDDs, more a marketing gimmick only.

Just like you build a highway that enable your car to run at 300km/h, but you car max top speed is 100km/h.

Only when use SSD, then you need Sata II interface because Sata I (1.5Gb/s) is not enough.

It has nothing to do with green version or not.

It just could be a bad batch only.

It doesn't make sense for a 2.5" to have e-sata. That's why you see little 2.5" come with it.
2.5" main function is portability and ease to use.
With e-sata, you either need adapter to power up the hdd, or need to use USB as power supply source. Either one means less portability and troublesome already.

For 3.5" yes, e-sata is useful.

Little difference.

A blue 16mb is still way fast than a 64mb green.

Just initial burst speed difference only.

Want reliability?
Backup.

It is not right to pro-claim which brand is more reliable than the others, as the actual defective/RMA rate is never being published or known.

I repost at here, as I find many misunderstand about the failure rate issue. It is not about Seagate HDD failed more than 50% or WD HDD failed 19%.

Less power consumption.

Some claimed less power consumption, lower heat -> more reliable.
Some also claimed less platter, less prone to Hdd failure, as you need either 1/4 platter to fail, then whole hdd might not be used anymore as compared 1/3.

Higher density, lower seek time.

But I would say, all above are negligible effect.

For computer hardware, always buy what you need time.
Don't need future proof, nor wait for newer stuff.

Wait for F4 time, may wait for F5, and forever waiting....

Now we know why there is no 3TB internal, you need specific mobo to support it.

It is as same as 64 bit issue.

When there is little advantage of shifting to newer hardware/tech/OS, then there is little reason for people to fork out extra money for it.

It has to do with cost wise as well on both front, customers and manufacturers.

Yup primary issue is about OS issue.

BIOS.

That's why external come out first.
As in normal circumstance, it is always internal first.

32 bit OS also needs to throw out of window aka XP only recognise 990MB out of 3TB.

The hardware is hitting some limitation, and need to overhaul the current standard to move forward.

But I expect, it will be slow process, as same as 64 bit migration, (even 64 bit has been available for years), we are still stuck with 32 bit across even now.

As there is no urgency to use a 3TB HDD especially for OS disk, you don't require such a capacity for OS.

Correct me if I am wrong. As still new to the issue.

IDE = Pata

eSata = external Sata.
There is mobo, casing that come with eSata port interface to connect the external hdd.

eSata port is slightly different with ordinary Sata port, which you cannot plug ordinary Sata cable into it one. It is basically a Sata port using interface/plug different.

There is not 2TB per platter.
Max capacity currently is 667GB per platter

Haha, I asked 2 times before on 2 shops.

Shop 1, Sales person A
I: what is the model for this samsung HDD in the price list
A: This is the lastest model
I: I want to know the exact model code
A: 1TB
1: err... never mind.

Clearly wasting time in asking, just ask A to bring out and see the HDD directly myself.

Shop 2, Sales person B
I: What is this samsung model
B: Ecogreen
I: I know it is ecogreen, I want to know its exact model no.
B: Samsung Ecogreen 1TB.
I: .......

One of my office is using it as OS disk. Run cool, pretty ok.

Should be the 16mb blue.

Bigger cache effect is only more visible during start burst up time.

Blue version is difficult to get nowadays, most shops don't want to stock up.

Yes you can.

Sata I,II,III difference is the interface speed they can deliver.

But HDD limitation come from its speed ability itself aka write/read within itself, not the interface of Sata.

Just like a car that has top speed on 120km/h,
putting the car into a highway that can drive 120km/h vs 240km/h, make little difference.

Still the same port/cable.

For the statistic, you need to take in the sample size as consideration.

If sample size is too small, it can be influenced by outlier number.

When SSD first coming out, a lot of laptop manufacturers start to introduce SSD based laptop.
But now, it seems like most laptop manufacturers still going back to 2.5HDD as their main-stream selling model.

May be cost wise really can't compete.
