Hi Chris,

Could there be an option for 'spinning disk
additional storage' which my VPS would see as a separate disk? Or would that make
things too complicated?
A number of people are asking for this. Probably enough of you that
I would be foolish to not offer it.
Just bear in mind that:
- Networked storage is something BitFolk has never done.
- It introduces lots of new failure modes that you don't typically
see on the small length of cables and electronics that would
normally be all that separates a server from its storage.
I'm not saying that it's rocket surgery to do resilient network
storage, especially when it's not intended to be high-performance.
Just that it is definitely a project.
Probably things have to go like this:

1. Get everyone migrated to new hardware while keeping additional
storage prices the same.
2. Implement networked archival storage in a way that has some
reasonable level of resilience such that the first server or
switch failure doesn't leave it totally inaccessible.
3. Offer it for cheap, in comparison to SSD.
4. Put up the cost of additional SSD-backed storage to something
more reasonable. BitFolk's current list price is £0.08+VAT per
GiB (sold in blocks of 5GiB) and that is too low for SSD.
