Unraid Quickie - How Does Parity Protection Work?

[@Itsallfun3000]

Exactly what I was looking for well explained and not a 20 minute video with tons of noise

[@verminfate7074]

Amazing video, really cool how you explained it in 5 minutes and didn't take longer.

[@BelieveInTheLordJesus777]

Thank you. Would be nice to explain how dual parity works too, thanks.

🎯 Key points for quick navigation:
00:00 *📹 Introduction to Unraid parity protection with one parity drive.*
00:14 *💾 Unraid setup includes multiple data disks, optional cache disks, and up to two parity drives.*
00:28 *🧩 Parity drive must be as large as or larger than the largest data drive.*
00:41 *🔍 Parity works by ensuring the sum of data slots is even.*
01:22 *🔢 Example of how parity is calculated using binary values.*
02:32 *⚠️ Unraid can reconstruct lost data from a failed disk using parity.*
03:04 *➕ Advantages of Unraid include the ability to add new drives of any size at any time.*
03:19 *💡 Data on non-failed drives remains accessible even with multiple drive failures.*
03:48 *📈 Unraid maintains decent read speeds, limited only by the speed of the individual disk.*
04:01 *🐢 Writing speed is slow due to the need to update parity for every write operation.*
04:15 *🏞️ Unraid is ideal for storing large amounts of static data like movies and pictures.*
04:27 *💾 Unraid is not suitable for frequently changing data like active databases.*
04:41 *👍 Invitation to learn more about dual parity setups and enjoy using Unraid.*

I agree with the other comments. Very well made and clear craftsmanship. Bonus cred for using unraid-orange in your animations. 👏

[@Venaloid]

Perfect, exactly what I needed to know. Thank you!

New follower here and this is an AWESOME VIDEO!!! Please add the dual parity video to your playlist.

[@mil1ion100]

This is a perfect TH-cam video, makes perfect sense! Thanks for explaining in under 5 mins

Okay bit how does daul pairty work sure if you did this twice it would allow two drive to fail only both pairty drives..

[@anthonychallis2472]

Great video, now I understand, thanks.

[@hamurabidios]

I have two 8tb hdds. Can't i just mirror them so if one fails i have the other until i replace the first?

[@techngo8473]

Hi, your setup works great if you just have 2 drives. You loose half your capacity but can loose one drive without loosing data.
With unraid once you ad more drives you get to use their whole capacity and only loose that single parity drive in capacity. If you keep mirroring you always loose 50% of your capacity.
Another benefit is that you can add smaller drives no problem. For example:
4x8, 2x4, 1x2
And you just loose 1x8 in capacity

@@techngo8473 i forgot to tell you that my hdds are usb externals. Can they be used on unRaid?

[@techngo8473]

USB externals can be used in unraid. I ran 3 of them for quite a while. They do tend to have a higher failure rate in the long run than internal but they did run alright for quite a few years. One of them then started showing signs of failure after about ~3years

[@hamurabidios]

@@techngo8473 does unraid stress the disks more than their usual?

[@patm95]

Please explain dual parity

[@bonienl4550]

Nicely explained, thank you.

[@terrym.6795]

Great video!

[@39zack]

Would like an video on dual parity too :D

[@levin55555]

Thanks great Video!
