Linux

Recently, I bought a pair of those new Western Digital Caviar Green drives. These new drives represent a transitional point from 512-byte sectors to 4096-byte sectors. A number of articles have been published recently about this, explaining the benefits and some of the challenges that we'll be facing during this transition. Reportedly, Linux should unaffected by some of the pitfalls of this transition, but my own experimentation has shown that Linux is just as vulnerable to the potential performance impact as Windows XP. Despite this issue being known about for a long time, basic Linux tools for partitioning and formatting drives have not caught up.

gparted get it's right:

"When enabled, Round to cylinders aligns partition boundaries on the cylinder boundaries for the disk device. Enabled is the default setting."

The Ubuntu installer uses Partman from Debian, which uses parted in the background.

So that's a start.

But if parted will do it right when run from partman, I don't know yet.

I just had a look at what partman does and what parted does. Parted does align by default as well, just like gparted. And partman just passes the MB's to parted, if I looked in the right places. That means it will do the right thing by default I think.

Aligning partition to "cylinder" boundaries is BAD. The cylinders are fake and they're in units of 63.

You could be right.

I guess my brain is off because it's weekend.
