Hello everyone,
A doubt that gnaws at me... is a 7200 sata2 drive better than a 5400 sata3?
I did some research and for mechanical drives there is controversy in opinions and tests. Some say that 7200 is always better, others that sata 3 improves bandwidth and if the drive has high data density it improves ratios against rpm.
Does anyone have any insight?
For my part I did some tests with two drives I have, a 500 Gb wd caviar black and a 2 Tb wd green with Crystal disk mark 3 and in sequential it gives me the black 46/45 mg in read/write and the green 76/57 idem
The problem is that the black is pata and the green is sata3 connected to sata2, quite a mess.....
Best regards

It depends on the use… If you have to choose between the two with the idea of using it as the main disk for the system, I would go for the 7200rpm sata2. It's that an SSD is what it needs, but well, I have the worst mix of the two and I survive... Sata2 5400rpm :ugly: :ugly: :ugly: :ugly:

That's like asking in cars "displacement vs road" which will run faster: a 1,800 engine on a highway or a 2,000 on a national road? The answer is that it has nothing to do, it's like mixing bacon with speed.
About the revolutions of the disk it passes like the example of the displacement, a smaller engine sometimes develops more horsepower than a bigger one, so you have to look at the HP. Today there are disks that go to fewer revolutions and yet they perform as much or more than others of more speed, so what really matters is the performance, you have to look at each model and see how it performs.
About SATA 2 or 3, the difference you have in wikipedia, and as you will see for a mechanical disk it gives you exactly the same. And PATA as there are different versions it will depend on which one, which by the way also appears in wikipedia in case you are interested in knowing what it is.
