Now that we're talking about B2, has or is anyone using them for latency-sensitive small-file object storage? I'm about to take the plunge and set up benchmarks, my use-case is that I want to store and serve ~ 500k small files (30b-1MB) per day to website visitors. So far B2 support has told me that it shouldn't be a problem, and early benchmarking indicates the same, just curious if anyone had stories from the trenches.
