That command, on my system anyway, does pick up all the
LBA sizes:
1) Windows - 1TB Sabrent:
Supported LBA Sizes (NSID 0x1)

0 + 512 0 2

2) Kubuntu - 1TB Crucial

3) Scratch pad - 128GB SSSTC (No name) M.2 chip mounted on Joylifeboard
PCIe card

No Errors Logged
NOTE: When I first got interested in M.2 I bought a PCI Express
card and an M.2 chip just to use for a while with Astrophotography
files which tend to be 24MB coming out of my camera but grow
to possibly 1GB as processing occurs. Total cost was about
$30 and might be a possible solution for Gentoo users who
want a faster scratch pad for system updates. Even this
second rate hardware has been reliable and it pretty fast:

away the Crucial M.2
