Does Ripple node require 6.8TB disk storage?

[YuriF]

And 8-12GB per day ? Is it real? Getting from docs: https://developers.ripple.com/capacity-planning.html

If you want/need full history, yes - but probably a bit more than that by now. Make sure it is all SSD too.

Just look at the transactions per day metrics at https://xrpcharts.ripple.com/#/metrics and then compare them to e.g. Ethereum or Bitcoin... Even though transaction sizes are not 1:1 the same, you can get a good feel for how much storage is actually required to store all these transactions and the changes they cause.

Why is it important to make sure you use SSD?

[Sukrim]

Because you need to have high performance when looking up historical data which is more or less randomly distributed all across the database.

Storing this data indexed on HDDs is probably possible, but would have a huge overhead and it is also not implemented at the moment... There's someone on this forum who wants to run on hybrid disks (HDDs with SSD cache), maybe it works out for her/him?

If I don't want to see a full history, just to start from today. Can I configure like that?

Yes. nikb wrote a useful blog about setting up a validator http://nik.bougalis.net/2018/05/18/securing-validators/
