I’ve never heard anyone else mention them, but I’ve had really good luck with https://www.ssdnodes.com for the past several years. I don’t recall ever using their support, but I did have a policy question before buying when I first signed up and they were pretty quick to reply. I think I found them on LowEndBox.
Could be. If that’s the case, it’s nothing I’ve noticed. I’ve got a 32gb VM and I’m running a bunch of LXC and docker containers on it without issue.
