Do you make anything from it?
For the first few months, you'll basically have all of your Sia drained as your contracts start coming in and your host wallet gives them collateral. But yeah, my contracts only recently started to complete, and I've got the amount of Sia I started with at the very least. So... Yes, but probably not very much? Particularly when accounting for the price drop in Sia. Edit: If you do decide to host, it'll likely be abou…

Thank you so much! Is there a limit on size of objects besides the 5TB max described in the docs, similar to other object stores where multiparts have lower limits than the total composed object?
There is also a lower bound of 0 bytes :) You can compose a 4TB object with a 1 byte object, or you can compose 32 150GB objects, just so long as the destination object doesn't go over 5 terabytes.

#184I work in telecom/datacenter infrastructure and this is fanciful. The whole way they take the wattage load of one machine and then hand wave away all of the rest of the costs of either building and running a datacenter, or paying ongoing monthly colocation costs... Is just scary. I truly don't mean to offend anyone but this looks like a bunch of enthusiastic dilettantes. Generators? UPS? Cooling costs? Square footage…

Backblaze is operating at their own economy of scale with dedicated deals with suppliers, custom bare bones hardware, optimized processes, etc. It's always more expensive starting out as a little company for raw hardware and processes until you're big enough and mature enough to get the deals and processes in place. That is also not the only service that Backblaze offers and wasn't their first. It could be that B2 is…
If all their other customers on the $5/month unlimited backup plan store less than 1TB, but since it’s really aggressive about backing up everything (no, please don’t back up my steam games) on your computer I think they go over that.

#187How did they go from 8 SATA ports to 32 SATA devices? The linked cable uses a SAS host/connector. Was a SAS card left out of the parts list?

#189I worked on the design of Dropbox's exabyte-scale storage system, and from that experience I can say that these numbers are all extremely optimistic, even with their "you can do it cheaper if you only target 95% uptime" caveat. Networking is much more expensive, labor is much more expensive, space is much more expensive, depreciation is faster than they say, etc etc. I don't think the authors have ever done any actua…
THIS! There's no use of a 2TB storage if you can't upload/download this amount each month
Re: Cloud Storage for $2 per TB per month
#190The problem comes when you want to store multiple files. If the corresponding erasure code fragments from different files are not stored on the same server then you don't have correlated failures. Contrast this with a typical raid scheme where a failed drive means the nth erasure fragment of every file is gone - correlated failures. If the failures across different files are not correlated, which is the case if you're storing each new block on a random node, then you are basically guaranteed to lose data if you have enough files. Depending on your scheme, this can happen as low as 1 TiB of data for a user. It is similar to the birthday paradox.
For erasure codes to work for a filesystem you need to have correlated failures.
