Price out a 1TB ebs volume with similar performance to a local SSD.

For gp3, you only get 3000 IOPS and 125MBps throughout, without paying extra. That is orders of magnitude less than a local consumer-grade SSD.

Spec it up to 100k IOPS and 5000MBps and you're looking at nearly $800 a month. And that's still way less performance than you get with a local SSD.

Spec it up to 500k IOPS (approaching nvme SSD performance) and you're looking at $2500/month. Now you are on par with a consumer grade SSD.

If you truly need that kind of perf (and at Amazon, we had plenty of dev desktops running on ebs without that kind of performance) then you should really opt for an instance type with local storage.

Yeah, that's a good callout.

Ive been deep in to implementing macOS CI workers on AWS where that isn't an option (or rather, it is an option, but it is unsupported and Amazon only buys Macs with the smallest possible SSD for the given configuration). So your options are to pay an arm and a leg for fast EBS, or pay an arm and a leg for a pro or max instance with larger internal SSD.

But on Linux there are better options.
