OVH HDD vs NVME / RAID / Proxmox
I've just ordered a server at OVH (16GB RAM, 2x450GB NVME drive) but having second doubts and would prefer more storage space.
The same OVH server is also available in 2x4TB HDDs.
The server I will be using for hosting no more than 6 VMs (or perhaps LXC containers, I'm thinking Proxmox).
The use will be mainly for web/database hosting but may also want to have 1-2TB worth of static mp3s for streaming to the public potentially utilising the 500Mbit connection.
I don't have a lot of experience with RAID arrays and hosting VMs on HDD.
Can I trust OVH's HDD's to handle this load including VMs and streaming? Will the hard drives be slowing down things for me to an unacceptable level?
In case one drive failed, what are the chances of rebuilding the software raid? I've been researching a bit into RAID rebuilds and found a lot of discussions about URE (unrecoverable read errors) during rebuilds on large (2TB+) drives due to the predicted URE rates.
How are OVH HDDs in terms of reliability?
Of course, I would be utilising the OVH 500GB backup space for essential backups. Also, I'm thinking about getting Pcloud's 2TB lifetime offer for backups.
What I realise is that it is fairly easy to spin up another server at OVH (120 second delivery!) so restoring from backups does not seem too bad if it came to it).
Alternatively, another option is to get two servers and have Proxmox's storage replication so nearly realtime backups would be available (https://pve.proxmox.com/wiki/Storage_Replication). As I understand a complex setup for this is not needed (no GlusterFS etc.), however I am a cheapskate and would like to save some money here.
I'm sorry I am touching a few subjects here in my ramble - but would appreciate any help on any of the points or suggestions for a better setup with backups etc.
