Is Linux Ready for 4096 Byte Sector Hard Drives?

Okay, so IF you're stupid enough to intentionally use odd starting sector then you get the same performance as Windows will always have with these drives, woopdie do!  


Let's make a mountian out of a molehill and spread fear uncertainty and doubt throughout the land, calling it a study. *rolls eyes*



The so-called "green" drives spin at about 5400rpm. Some can speed up to 7200rpm, but that takes time to happen. Could this be affecting the test results? Try using a Velociraptor. Or, just an ordinary 7200rpm.

That's just the hard drive issues alone. How about the CPU, ram, or even the version of Linux.

I like Linux, but I can't play Rosenkreuz Stilette on it.



The problem is known and the issue is the annoying backwards compatability hack the manufactuers use so the drives will work with windows XP., which has no idea how to handle sectors larger than 512 bytes.

Basically, the drive uses 4096 bye sectors, but presents itself to the OS as having 512 byte sectors and shuffles between them in the firmware.

Linux trusts the hardware and treats the drive as having 512-byte sectors, which results in this misaligned sectors issue.



I think the purpose of the tests were to show the difference in time, not to benchmark anything. so the hard drive, CPU, RAM, and the like would not make a difference.
