He's absolutely clueless. Drives used in EMC storage arrays, for
example, which usually contain hundreds of drives, are usually (perhaps
always) formatted to 576 bytes/sector.
Most SCSI-protocol drives (whether they use the "SCSI" physical layer
or not) can be formatted to any sector size you want.
The same goes for SMD; the formatting is handled by the controller in
that case.
Still, somehow, people like that manage to get published. I just
don't get it.

"From the time of their first availability in the 1950s until about
2010, the sector size on disks has been 512 bytes."
This isn't even true for SCSI disks, much less all the different kinds
before that.
Indeed. I've seen hard drives with sector sizes all over the place.
256 bytes and 1024 bytes weren't unknown on SCSI devices .
The author's probably never even seen an IBM 1311 or Bryant 4000.
