>Description:
Intel's 320-series and 510-series SSDs advertise 512-byte sectors
sizes for both logical and physical. This adds ADA_Q_4K quirks
for both. (Intel, for whatever reason, didn't add physical sector
advertisement in ATA IDENTIFY; maybe they're strictly adhering to
non-draft specs, I don't know...)
Validation of my claims:
