RAID and standard RAID levels(0-6,10) in Operating System

In this video i will explain RAID in operating system and general RAID levels and comparison between RAID levels.
What is RAID? - Redundant Array of Inexpensive/Independent disks.
RAID explanation.
RAID is the technique in which we use multiple physical hard-drives together as a single logical hard-drive.
Standard and basic RAID Levels and comparison between RAID levels in operating system.
RAID 0: It stripes the data and stores it in the available disks. Striping can be at bit/byte/block level.
RAID 1: It uses mirroring. It makes copies of all the available data and increases reliability
RAID 2: This uses Error Correcting Code(ECC) like hamming code. More than 2 bits are used to store the ECC so minimum 3 dedicated disks are required to store the ECC.
RAID 3:This is bit wise separation of data.Instead of ECC it uses Parity. Only 1 bit is used so only one dedicated disk is required. It increases data transfer rate but doesn't increase number of accesses.
RAID 4: It is similar to RAID 3 but here data is divided block wise.It increases number of accesses but no improvement in performance.
RAID 5:Instead of using dedicated disk for storing parity information it divides the parity info across all the disks. It uses 1 bit for parity.
RAID 6: It is similar to RAID 5 but it saves 2 bits of parity information.

RAID 0 -> 01:00
RAID 1 -> 01:50
RAID 2 -> 02:27
RAID 3 -> 03:16
RAID 4 -> 04:34
RAID 5 -> 05:38
RAID 6 -> 06:37
RAID 10-> 07:05

Wow! This explanation was so clear and concise. Thanks a ton!

[@vaishnavisavant6478]

Such a very nice explanation as it clears all the doubts about RAID levels clearly...Excellent..

[@pujithagaddale7171]

Pls tell me is raid structure and raid levels are same ???

[@lalitchougule7155]

I thought of watching it at 2x lol!!

[@sahithiyantrapalli4112]

Can u tell problem with raid

[@giannaras2010]

can i ask something? if i have got 1 external HDD is it possible to raid this HDD's disks between them?
i know a HDDs have lots of disks inside them so, if it's possible to raid those disks between them this would give a great speed to external HDD or any HDD!

[@gadhamshettysanjay8156]

Bro can u send PPT
With your explanation ??

[@vaishnavim6625]

What is parity ?

[@uzairsaeed8744]

Can you please give me the link to download these slides?

[@naqihassanraza1806]

Only reading in the video no conceptual explained

[@pleasesirmorevideos4684]

that is why it is Last Moment Learning. I tried to learn concepts but i wasted y time in hamming code error correcting code etc etc.
