Certainly, you are correct :)
As general advice, 8 sectors is better because of advanced format. But
then you also have to account for modern SSDs, which have erase block
sizes between 128 and 512kB (256 or 1024 sectors), and for partitioning
hw-raid devices you need to know the stripe size of the underlying
device. When taking that all into account, the MS default of 2048
sectors is quite understandable.
But the drive in question was 600GB (iirc). Too large for an SSD and
too small for advanced format...
