R2 is very high latency with huge variance, definitely lower quality than S3.
In my experience even backblaze b2 performs (way) better.
Their community forums are full of such reports.
KV is so expensive that it’s barely usable, and like R2, is very slow.
Slightly higher latency. I've seen about 20-30% increase from S3 to R2. But the bill is magnitudes lower.
Agree with the KV point, Upstash is the same. But I just use dragonflydb on a single VM. No point paying for transactions.
Hell, S3 could have 20ms latency and it wouldn't matter since I can't afford it.
Where are you seeing orders of magnitude lower R2 bills? The storage price for S3 is $0.023 per GB, and the price for CF is $0.015 per GB. The operation pricing is even more similar - S3 is $5/million writes and $0.40/million reads, while Cloudflare is $4.50/million writes and $0.36/million reads.
Egress fees are the largest part of many AWS bills, this is by design, that price is deceptive. R2 has no egress fees.
