• nvmsetid — NVM Set Identifier ✨
• endgid — Endurance Group Identifier 🦋
• rsvd4 — Reserved. it’s giving “don’t touch” energy, bestie 💅
• rr4kt — Random 4 KiB Read Typical — this one indicates the typical time to complete a 4 KiB random read in 100 nanosecond units when the NVM Set is in a Predictable Latency Mode Deterministic Window and there is 1 outstanding command per NVM Set. yes, that’s a mouthful, but we keep it exact, fr fr 😭
• ows — Optimal Write Size 🌸
• tnvmsetcap — Total NVM Set Capacity 👑
• unvmsetcap — Unallocated NVM Set Capacity 🎀
• rsvd48 — Reserved. again: reserved, so leave it alone 💀
