Interesting thread.
I'm currently trialing Backblaze.
I've tried a dozen speed-tests on my broadband and all, including Backblaze's own, give my upload speed at 25-30Mbps.
But, the Backblaze upload app Performance tab is giving readings of 2-3Mbps for each file uploaded. At that rate, uploading 24/7, it will take over a year to complete. Useless. (My last service - can't remember who they were, but they went bust, a race to the bottom as said above - took just under 3 months for a similar upload.)
Does any service make better use of available bandwidth?
As someone who, with very rare exceptions, only preserves RAW files with their CaptureOne edits intact, I should probably revert to what I use to do and buy a couple of big USB sticks at the end of each year and simply copy. I'm not a very high volume shooter.
Thanks.

Ps. And, yes, the Manual Throttle in the app is set to Max.
