Q3. I plan to eventually buy a SATA HDD. I'm waiting for a 4K sector HDD
(aka "Advanced Format") which does not do 512-byte sector emulation, i.e
4K native. In the meantime, if someone in the group within a 10-mile
radius of downtown Poughkeepsie has an unwanted SATA HDD, make me an
offer.
IIRC Linux was patched for the 4K sector "Advanced Format" problem that
Windows 2000 ran into, so that shouldn't be a factor.
Which is true, but the real issue under Linux is that fdisk doesn't
(didn't? maybe now fixed) default to aligning on the 4k boundary. If
fdisk starts your partitions not on 4k boundaries, you get substantial
slowdowns when using those disks. Here are the tricks for doing the
alignment -
