I vaguely recall that 4-nines is common, but I think OceanStor Dorado might actually offer 5-nines.

I’m leaning towards option B, 5-nines, but I could be mixing it up with another vendor's specs.

I feel like I came across a practice question that mentioned 6-nines, but that seems really high for storage reliability.

I think I remember reading that high-end storage systems like OceanStor Dorado can provide up to 5-nines reliability, but I'm not completely sure.
