5400rpm Hard Drive with 3GB SATA ... what is the point?
Posted on 2012-03-11
Ok, I was just puttering around with some hardware today... and noticed that one of my old 160GB hard drives was 5400RPM (so SLOW), but that it was also SATA 3GB/s...
OK, so what is the point of having insane throughput on a HD with the second slowest RPM speed now available (I think that there used to be 4200RPM drives, or something like that).
Ok, so why do manufacturers do that? is there any benefit or is it just that the hardware standard these days is just becoming 3GB/s, so the manufacturers buy them for the same price as 1.5 GB/s hardware, for example, and gain a "misleading" selling point because they get to put 3GB/s on the HD box?
For my sanity, and instruction, can an expert please clarify this?
