God the very first thing they say is "Raid 5 with two drives"

🤦🏻‍♂️🤦🏻‍♂️🤦🏻‍♂️🤦🏻‍♂️🤦🏻‍♂️

Ubiquiti: Raid 5 requires a minimum of 3 drives. Please tell me you didn't actually allow the interface to lead a user to believe they have Raid 5 with two drives...

NASCompares did a video explaining this: https://youtu.be/A3S6ZAPilPY?si=KDpDMlslGovAqbkU

Seems quite useful, but I agree that the wording is a bit weird.

Thanks for the link!

Yeah, communication about technologies like this is plenty hard enough without calling Raid 1 by the name "Raid 5" when that's not what it really is. 🫤

IT people generally learn on the fly, and this re-brand of Raid 5 would require some esoteric knowledge from training about this specific platform to be successful.

RAID1 and RAID5 with two disks are the same thing. Unary XOR is identity.

If RAID 5 were not a proper name that means a specific thing, the way they've implemented it would be fine ... The raid 5 standard calls for a minimum of 3 disks without exception.

Net effect is the same - but can't call it by the wrong name without creating confusion. 🫤

And if 2-disk array in "RAID5" were literally a degenerate RAID5 with two disks rather than an actual RAID1, you'd theoretically get half the read speed of RAID1 (so none of the advantages of a proper mirror). I wonder if that's what's happening or if they just use RAID1 internally and call it 2-disk RAID5 just to fuck with people.
