Raidz1 or z2? One of the reasons I went with z2 is because of the “raid5 is dead” thing, argument basically being, drives are so large that if 1 fails, you are statistically almost guaranteed to encounter a read error during the rebuild when you no longer have any redundancy, so double redundancy is a necessity nowadays.

I use haproxy just for simplicity, with the https fronted in tcp mode with a tcp request inspect delay and acls using req_ssl_sni allows switching between multiple backend based on hostname, though if you only had 1 backend server then it could just be a raw tcp proxy. I have my stuff split between 2 local boxes that are both connected to the reverse proxy using wg so this works well for me.

I use a wireguard tunnel as a reverse proxy and it does ssl passthrough with sni. Termination happens on my local box and the reverse proxy host doesn’t do any certs.

I went with rsync.net, grabbed a promo at some point and have been getting 1.6TB for $10/mo. They support a wide range of protocols (sshfs, sftp, rsync, borg, synology, guides for freenas and truenas), snapshots, idle alerts, geo redundancy for a fee. Been very happy with it so far. Had to retrieve some files once and had no issue.
I couldn’t find a common compatible format for me and 15 friends :( I also got tired of getting 20 requests to download more movies and episodes every week.

I’m curious if it could solve the traffic light and crosswalk ones, I would try but I’m out of free image uploads from asking it to explain memes to test its cultural knowledge.

Raidz5 doesn’t exist, I assume you mean raid5? And you wouldn’t know, URE is sometimes silent, and because without parity during a rebuild you would be recalculating the parity bit and assumig every read on the remaining drives is successful. Except the URE rate for drives hasn’t gone down to match the increasing size of drives - so for a full 1x read of a large drive, you’re statistically at risk to get at least 1 URE.
In short, there is no integrity checking when rebuilding a single redundancy array after a drive failure, so just because a rebuild succeeds, doesn’t mean nothing was lost or corrupted. With double redundancy, you will still have single redundancy during a rebuild, so you would be able to detect URE and retry reads or raise an error to the user.
Some articles may make it overblown - you won’t lose your whole array, but any files stored in the block that had the URE during rebuild would be lost. And you might not know that it happened.
