to run AH is it better a 2,5 or 3,5 inches hard disk ?

It doesn't matter. 2.5" drives are considered "portable" or "laptop drives". 3.5" are the standard desktop ones.

Size makes no difference whatsoever. It's the other qualities of the drive that matter.

Except SSD disks where 2,5" is the norm. The 3,5" drives are an oddity in that field - so if it's going to be SSD go for 2,5" - more selection and lower prices in that category.

And if you are going the standard hdd way, 3.5" hdd's are cheaper, faster and more reliable. They also consume more energy and produce more heat than 2.5" ones. Just don't choose any "green" hdd for gaming: They are slow to reduce energy consumption, heat production and noise.

Green HDDs are not slow, just a bit slower than usual drives because they use 5400 to 5900 rpm instead of 7200rpm. Has also the positive side-effect that you typically don't hear them operating. Vibration is also reduced.

5400 rpm is glacially slow. All transfer rates are noticably slower, and seek times are longer as well.

I've used 5400 and moved up to 7200, then moved on to SSD. The jump from 5400 to 7200 was almost as noticable as the one from 7200 to SSD.


Not as big a jump, but just as "noticable," IMO.

It's all very relative in the spinner disks. A 4Tb 5400rpm drive can be faster than a 1Tb 7200rpm drive due to the higher platter density. But if you compare two disks with similar sizes then usually higher rpm is the faster one.

[Denniss]

The jump from a similarly sized/equipped 5400rpm to 7200rpm drive is hardly noticable except in max sustained transfer rate. It all depends on what you want - maximum performance or silence.
SSD offers both but at a risk of limited lifetime and high cost for their size.

It is tradtionally better to go with a 3.5 hd because the smaller ones always had lower throughput (when comparing magnetic storage).

7200 RPM will run AH better than 5000 RPM.  Size doesn't matter.

[Torquila]

Size does matter.

[Denniss]

7200 RPM will run AH better than 5000 RPM.  Size doesn't matter.

Do you really believe a 250GB 7200rpm HDD is faster than a 1TB 5400rpm?

[MrRiplEy[H]]

7200 RPM will run AH better than 5000 RPM.  Size doesn't matter.

You mean to say the drive size doesn't matter BUT:

Higher density drive = faster drive when spin rate is equal
Higher rpm drive = faster drive when density is equal

However if a lower rpm drive has double density, it can deliver data faster than the faster rpm drive with half the density. This is generally true even when accounting for the changes in seek times.

Physical size doesn't matter.  The speed that the platter rotates does matter.
