How many hours of 4K video can the 512GB iPad Air store

Given this range, let's calculate the storage capacity for 4K video on the 512GB iPad Air:

1. Total Storage Space: The iPad Air has 512GB of storage. However, not all of this space is available for video storage due to the operating system and other pre-installed apps. Let's assume about 450GB is available for user data.

2. 4K Video File Size:
- Lower Estimate: 300 MB per minute
- Upper Estimate: 500 MB per minute

3. Conversion to Hours:
- To convert minutes to hours, we divide by 60.

4. Calculation:
- Lower Estimate: $$ \frac{450,000 \, \text{MB>{300 \, \text{MB/min> = 1,500 \, \text{minutes} $$
- In hours: $$ \frac{1,500}{60} = 25 \, \text{hours} $$

- Upper Estimate: $$ \frac{450,000 \, \text{MB>{500 \, \text{MB/min> = 900 \, \text{minutes} $$
- In hours: $$ \frac{900}{60} = 15 \, \text{hours} $$

Therefore, the 512GB iPad Air can store between approximately 15 hours and 25 hours of 4K video at 30 frames per second, depending on the video's compression and content. This estimate aligns with the general guideline that the 512GB iPad Air can hold about 994 minutes of 4K UHD video, which translates to around 16.57 hours[1].
