Explanation:

The time required to rebuild a drive primarily depends on its maximum write speed, which is typically around 30 MB/s. To estimate the rebuild time for a 14TB drive, follow these steps:

• Convert 14TB to MB:
  $14 \, \text{TB} \times 1024 \times 1024 = 14,680,064 \, \text{MB}$
• Divide by the Write Speed:
  $\frac{14,680,064 \, \text{MB}}{30 \, \text{MB/s}} = 489,335 \, \text{seconds}$
• Convert Seconds to Hours:
  $\frac{489,335}{60 \times 60} \approx 136 \, \text{hours}$

Thus, the estimated time to rebuild a 14TB drive is approximately 136 hours.

Note:
This estimate assumes that the system is solely focused on the rebuild process. If the system is concurrently performing I/O operations, the rebuild process will take longer than the estimated time.
