Yes, they absolutely can [1].

That's unrelated to the performance of (for instance) the R2 storage layer. All the bandwidth in the world won't help you if you're blocked on storage. It isn't clear whether the overall performance of R2 is capable of saturating user bandwidth, or whether it'll be blocked on something.
S3 can't saturate user bandwidth unless you make many parallel requests. I'd be (pleasantly) surprised if R2 can.
I'm confused, I assumed we were talking about the network layer.
If we are talking about storage, well, SATA can't give you more than ~5Gbps so I guess the answer is no? But also no one else can do it, unless they're using super exotic HDD tech (hint: they're not, it's actually the opposite).
What a weird thing to argue about, btw, literally everybody is running a network layer on top of storage that lets you have much higher throughput. When one talks about R2/S3 throughput no one (on my circle, ofc.) would think we are referring to the speed of their HDDs, lmao. But it's nice to see this, it's always amusing to stumble upon people with a wildly different point of view on things.
We're talking about the user-visible behavior. You argued that because Cloudflare's CDN has an obscene amount of bandwidth, R2 will be able to saturate user bandwidth; that doesn't follow, hence my counterpoint that it could be bottlenecked on storage rather than network. The question at hand is what performance R2 offers, and that hasn't been answered.
There are any number of ways they could implement R2 that would allow it to run at full wire speed, but S3 doesn't run at full wire speed by default (unless you make many parallel requests) and I'd be surprised if R2 does.
n = 1 aside.
I have some large files stored in R2 and a 50Gbps interface to the world.
curl to Linode's speed test is ~200MB/sec.
curl to R2 is also ~200MB/sec.
I'm only getting 1Gbps but given that Linode's speed is pretty much the same I would think the bottleneck is somewhere else. Dually, R2 gives you at least 1Gbps.
No, most people aren’t interested in subcomponent performance, just in total performance. A trivial example is that even a 4-striped U2 NVMe disk array exported over Ethernet can deliver a lot more data than 5 Gbps and store mucho TiB.
Thanks for +1 what I just said. So, apparently, it's not just me and my peers who think like this.
Cloudflare's paid DDoS protection product being able to soak up insane L3/4 DDoS attacks doesn't answer the question as to whether or not the specific product, R2 from Cloudflare which has free egress is able to saturate a pipe.
Cloudflare has the network to do that, but they charge money to do so with their other offerings, so why would they give that to you for free? R2 is not a CDN.

k
that's completely unrelated. the way to soak up a ddos at scale is just "have lots of peering and a fucking massive amount of ingress".
neither of these tell you how fast you can serve static data.
>that's completely unrelated
Yeah, I'm sure they use a completely different network infrastructure to serve R2 requests.
