Eu tenho uma unidade com tamanho de setor = 512 bytes ( /dev/sdb abaixo) e uma unidade ( /dev/sdc abaixo) com tamanho de setor = 520 bytes da seguinte forma.
# lsscsi -g
[0:0:2:0] disk ATA SDLF1DAR-480G-1H RP41 /dev/sdb /dev/sg1
[0:0:3:0] disk ATA SDLFOEAM-100G-1H RF12 /dev/sdc /dev/sg2
Eu tentei executar o VDBench no Ubuntu e o tamanho do setor = unidade de 512 bytes pode ser executado da seguinte forma:
/usr/local/vdbench503rc11# ./vdbench -f
Rnd_RD_4k_sdb.parm -o output/
Vdbench distribution: vdbench503rc11

Talvez você possa me dar algumas sugestões para que eu possa obter o tamanho do setor não-512 bytes do driver SCSI do Ubuntu, como tamanho do setor = 520 bytes, 524 bytes, 528 bytes e assim por diante.
