I like the fourth or the last one since it encourages all other error responses to follow a similar standard. That will allow the client to have a reusable error model and error checking.

I’ve had to use APIs where every response was 200 ok with json, 400 bad request with pain text that said unauthorized, or a 500 error that returned an HTML error page. The worst.

I personally wouldn’t use raidz1 because it seems too risky to me. I’d have higher redundancy.

The last link is talking about actual raid and not zfs. But it has a 50/50 chance with a URE rate of 10^14 to lose the array. Raidz1 maybe won’t have that catastrophic of a failure, but you’d still be rolling the dice on some corruption.

Other people gave a good explanation of raid and some alternatives like zfs in truenas.

You want to avoid RAID5 with drives above 4TB. Every hard drive has can have an unrecoverable read error (URE) during the read. It’s a very low percentage change that your hard drive publishes. During a raid 5 rebuild after replacing a drive, the other drives are stressed for a long time during the rebuild. With high capacity drives you have a pretty large chance of encountering a URE and losing the entire array. The high stress on the drives can also cause drive failure if another drive was on its way out.

I run truenas core at home in volumes that looks like raid 10. Two mirror volumes striped together for performance.

I never played around with raidz1 (like raid 5) but you still have the chance of an URE during the resilver. I can’t comment if it’s possible or what happens during an error. I did see people recommending raidz2 to allow for two disc failures from losing data during a resilver.

I’m interested to see what hosted options are out there as well.

If you’re willing to consider alternatives, take a look at Greenshot. It’s a free and open source local program that takes a screenshot which allows you to edit it directly and copy the image to clipboard without saving.

It includes the ability to add text, blur out parts, crop, draw arrows. Just press print screen to capture an image.
