What is parity and why it needs to be stored ..?

[@RealLifeHope]

​@@karunkarna9397Parity is more like backup within a drive. It is used to rebuild data stored in a drive incase of a drive failure. Basically, if a drive fails, parity is used to rebuild the data that's been stored which would be lost in a normal storage drive in let's raid 0

[@NoEgg4u]

If you want both speed and data redundancy, then (aside from some of the less common RAID configurations not covered in this video) RAID 5 would be best. RAID 5 offers close to RAID 0 performance, while maintaining data redundancy (in case of a drive failure). RAID 5 can (and should) survive a single drive failure (any one drive can fail), and no data loss should occur. Upon replacing the failed drive, the RAID controller will rebuild the array (populate the new drive with data), and upon completion, it will be like nothing ever happened. When a drive fails, the RAID 5 effectively becomes a RAID 0. So if yet another drive fails, before you replace the first failed drive, then you are doomed. And that first failed drive must be replaced, and the array completely rebuilt, before the array becomes fault tolerant (before it could withstand another drive failure). The time it takes to rebuild a failed drive mostly depends on how much data you have. The speed of the drives matters, too. Unless you have multi-terabytes of data, repopulating a new drive should take under one hour (and probably less than that). If you have multi-terabytes of data, it is still no big deal, as the rebuild will just take a few hours, perhaps. And you can use your computer what this takes place. When this video was made, RAIDs were a good way to squeeze out lots of performance from mechanical drives. However, with today's solid state drives (SSDs), a single NVMe SSD will outperform any mechanical RAID setup. Note that NVMe SSDs are far, far faster than AHCI SSDs (most, and by a wide margin, home computers have the latter, at the time of writing this comment (2019)). So if you want both super speed and redundancy, then a RAID 1, consisting of two NVMe SSDs, is the way to go. But you will have to find a motherboard that supports two physical NVMe SSDs. Lastly, a hardware RAID is best (as opposed to a software RAID). For example, if you use a software RAID 5, that means that you are using your operating system (probably Windows) to manage the RAID. This presents two problems. 1) There will be a performance hit, as your CPU will have to manage the RAID. In most cases, you will not notice this. But the next issue is serious: 2) If one of your drives fails, then Windows might not boot (depending on which drive failed). This is because Windows was managing the RAID 5, but Windows must be running in order to manage the RAID 5. In order for Windows to start, it reads only one boot drive (and if that is the drive that failed, then you are screwed). To put it another way, when Windows starts, it will start as a single drive (no RAID). Once it gets to a certain level in booting up, it will start the RAID service. But it must boot up in order to do this. With a hardware RAID 5, your array is managed by your storage controller (which is independent of Windows -- it runs before Windows starts). Also, the controller is independent of your CPU, meaning that it has its own processor that manages the RAID 5, and takes no toll on your CPU. Cheers!

You know I know this helpful and very very needed but at the same time I am beginning to find it pretty off putting and I am intimidated by ALL that I have needed to know before i can invest with confidence in this NAS technology. I am really going to stick with an old fashioned server and back up and I weary by all the do and don'ts and must do and must not do as we are not all techs. Just regular people wanting to spend and get value for money. That said, thank you for the info and the share.

[@bonkmaykr]

Good to know 👌

[@Hyp3rSon1X]

So if I can choose RAID in my Notebooks Bios... is that Windows handling the Raid in the end? Or does my notebook have an inbuilt Raid controller?

[@NoEgg4u]

@@Hyp3rSon1X If you have RAID enabled via hardware, then when you boot up you should briefly see "Press F2 for RAID options" (or something similar -- will be a similar message, and probably some other "F" key). If you do not see it, then it is possible that your BIOS is not displaying boot details (like total memory, etc). Find a way to enable that option, and reboot. Then, if you see a RAID message before windows starts, and it allows you to delete the RAID, create the RAID, choose the RAID level, etc, then that has to be hardware RAID (because Windows is not yet booted). Note that you should back-up all of your data before creating a RAID. It is easy (and sometimes necessary) to blow away your data when setting up a RAID. Once the RAID is in place, you could then load back your data. Depending on how you backed it up, you might first have to reinstall Windows and then restore your backup. If your backup program needs Windows in order to run (if your backup program did not create a boot disk for you to run the backup/restore software outside of Windows), then you will have to restore windows, install your backup application (so have that ready, and your registration key -- if needed), and then use that application to restore your data from your backup.

[@jagannathan1014]

Raid- redundant array of independent disks Striping: spreading data across disks, increases speed , not fault tolerant Mirroring : duplicating same values across different disks Raid 0- striping across 2 disks Thus no fault tolerance, more speed Raid 1- mirroring across 2 disks High fault tolerance, less speed Raid 5-striping with parity across 3 disks Good fault tolerance can be fully restored if only one disk fails , will give best fastest result with proper tolerance hence used widely, drawback is space required to store data is high Raid 6- same as raid 5 but with double parity to handle 2 disk fails at same time Raid 10 - first a raid 0 applied then to its branches raid 1 applied so speed as well as fault tolerance is present

[@kalpanagandham8455]

MrEliasish you are saying about "parity bit " it is a term comes while dealing with binary data , but seems here parity defines something else..

[@ramshadbasheer]

parity is the XOR of the data bits : in this case, layer 1 in disk 4 contains the parity = A XOR B XOR C

[@computerchy1980]

Ari Dani what i understand from the diagram i think ( parity ) is a partial datas that established from other disks to share and restore the missing data from failed disk , you notice the party from disk a + b + c + d = full disk , if 1 disk failed 75 % of hes data in spread in other disks ( in parity area ) , which it means its taken nearly 33.3% from each parity area of each disk ( parity area / 3 disks ) , so that means parity area is the mixes of 3 other disks , by collecting those 3 parities will give the 75 % missing failed disk data , what about the remaining 25% from the failed disk ? Its the parity data which it contains other disk data so it can be restored also by re establish it from 3 other disks datas again , and that means if more than 1 disk fails , you will loos data

[@rich1051414]

It's a mathematical checksum, the parity can be used to reconstruct a single missing block of data. It is worth pointing out that it is a very long process to reconstruct a raid 5 array with a failed drive, and not nearly as convenient as using raid 10.
