> One theory is that EC2 intentionally caps the write speed at 1 GB/s to avoid frequent device failure, given the total number of writes per SSD is limited.

This is the theory that I would bet on because it lines up with their bottom line.

But the sentence right after undermines it.

Faster read speeds would give them a more enticing product without wearing drives out.

They may be limiting the read artificially to increase your resource utilization else where. If you have disk bottleneck then you would be more likely to use more instances. It is still about the bottom line.

That could be. But it's a completely different reason. If you summarize everything as "bottom line", you lose all the valuable information.
