SSD (over nvme) and TCP (over 100gbe) both exhibit low tens of microseconds of latency as the low bound. This is ignoring redundancy for both of course, but the cost of that should also be similar between the two.

If the storage is farther away, then you'll go slower of course. But since the article is comparing to EFS and S3 Express, it's fitting to talk about a nearby scenarios I think. And the point of the article was that S3 Express was more problematic for cost than small-object performance reasons.
