I dont mean to be offtopic but does anyone know of a tool to log back into an Instagram account?? I was stupid lost my login password. I love any tricks you can give me!
Omg, thank you very much! I was trying to understand these types of volumes by reading about it but I just couldn't get the hang of it but with you explaining so clearly and showing images really helped!!
how about an array of 4 devices in pairs of raid 0, as i understand then you get redundancy and speed, twice the cost i think but twice the write speed and four times the read speed, or am i missing something?
Can i ask something? If i have got 1 HDD is it possible to raid this HDD's disks between them? I know that a HDD have got lots of disks inside of them so, if it's possible to raid those disks between them this would give a high speed to HDD.
Thank you for the detailed explanation. I was going to set up a Raid 5 array for my gaming machine, but now I think I'll just buy a 4th drive and do a 1+0. If that proves too difficult, I feel safe using Windows Storage Solutions now too. If you reply, do you know if there is any way to change Windows Storage Solutions from a Parity to Mirrored without having to rebuild the drives?
1+0 is a good option if you have the money to spend on the hard drives. You will need to rebuild the drivers if you change from parity to mirrored. The data is structured very different.
why do not raid 1 with mirror data improve read speed? the raid controller could just read a bit from each copy of the data using the 2 discs, at least read first half of one disc and last half from other.
The video is really good, especially the explanation about RAID5 and RAID10, but by now some things are not right anymore. RAID can be booted, for example BTRFS or ZFS. JBOD also means that you can access each disk individually. This is mainly used by software RAID and other storage solutions. The redundancy and speed brings the overlying software. A software RAID can today also support different disk sizes, such as a single RAID10 mirror. Even the statement that you can not expand a RAID is not correct in this context. With RAID1, both disks can be read simultaneously, so it should be twice as fast in reading. It should be made clear that the speed in reading corresponds to the transmission rate of all data disks. In the worst case, the speed in writing corresponds to the number of disk groups with the sum of respective disk speeds. Also, the term pool related LVM is not quite appropriate. These are called aggregates. Pool is rather complete to see. LVMs today are mostly the same or the same storage units. In a pool different stores can be combined. Modern object storage systems, which use erasure coding as an example, use these different types of memory for different speeds, without the user having to move the data from one memory to another.
Thanks for the feedback. I don't doubt things have changed since we did this video. It depends also on the implementation will determine what it can and cannot support. Usually hardware RAID will support more than software RAID. I will keep your points in mind for when we create our next RAID video,
Hardware is consider to have better performance then software. In case of recovery that is questionable. If you have software you only need to put in that hard disks in a computer that supports that kind of software RAID. E.g. in Windows you could remove the drives and place them in any Windows Server to read them. In the case of hardware, you would need to place them in a computer that supports that RAID solution if you had a hardware problem. With good hardware systems you generally do not have to many problem expect replacing failed drives.
The minimum number of disks in a RAID 5 set is three (two for data and one for parity). It's theoretically possible to use 2, but any RAID controller I've seen won't let you do that and it won't have any redundancy whatsoever.
Hello everyone....Will Windows 7 Enterprise edition will work with RAID 10 controller? Will Windows 7 Enterprise see logical drive after creation of RAID 10 ? Thank you
You need to check with the manufacture of the Raid controller to see if they supply a driver for the operating system you want to use. If they do it should work.
+Brandon Larsen You're very welcome. There will always be dissenting opinions. However, we appreciate those who love and watch our videos so we give them exclusive attention.
i am sorry to say that i do not understand what is raid 0 or the other raid i have been trying my best but i just don't get it your video is nice but i am still confused sorry
Who think RAID 0 is a good idea? It's good for speed but not for long-live data. I am looking for how effective the drive fully store data, not speed. So, RAID 1 for the server.
Depends what you are trying to achieve. If for example you are storing cached data you want max speed, but don't care if the data is lost because it will just be cached again. However, if your data is important to you, I would always recommend some sort of redundancy unless you want to resort to backups.
Thit was the BEST video about raid/storage I have ever seen. Congratulations!!!
apzeiroturbo Thanks very much.We're glad you enjoyed the video
BEST TRAINING VIDEOS I HAVE EVER SEEN .Thank You good peoples for doing this job.I wiev all your videos with great pleasure
Thanks very much and thanks for watching.
I dont mean to be offtopic but does anyone know of a tool to log back into an Instagram account??
I was stupid lost my login password. I love any tricks you can give me!
I was one of those ppl. Now I have an easy way to remember it! RAID 0 = 0 redundancy! 🙂👌🏾
Thank you!
Glad we could help.
Understanding RAID was never This EASY.....
HATS OFF......

A very well-done slideshow visually. Like the single useful video on the subject.
Thanx, itfreetraining!!!!!!!

Highly professional videos. Thank you itfreetraining for these videos
Jehangir Ahmad Thank you, happy to hear you found our videos helpful
These are amazing videos. I am loving it.
One can bacome a very competent Sysadmin in no time with this channel. Really high quality lessons!
+ComandanteJ Thanks for the great feedback! We strive to create the best content, for free!
FINALLLY!! A good explenation of RAID 10 and 5. THANK YOU :))))
You're very welcome!
great tutorials as always thanks
You're welcome. Thanks for watching!
As an IT student I enjoyed it. Thank you very much. Greetings from BC

You're very welcome, we're glad you found them useful!
your videos are awesome, explaining with figures are very useful. can you upload SCCM training vidoes? Thanks a lot
We'll take that into consideration. Thanks for watching!
Thank you so much for this useful video
You are most welcome
Nicely explained!
Thanks for all the great videos. One quick question which software do you use to creating these videos?
i dont know but i guess its powerpoint or proshow producer
Thanks for video tutorial now i understand Raid
I really enjoyed the video, Thanku for such a good series..I have a question . is it possible to use LVM on windows server 2012?
well explained sir...tq
You're most welcome
thank you best training videos
Thanks very much for you great feedback!
Thnx a lot👍👍👍
Great video. Thanks

Is hardware RAID better than Software RAID.
Which is better in terms of performance and quick recovery in case of drive failure.

If you have software you only need to put in that hard disks in a computer that supports that kind of software RAID. E.g. in Windows you could remove the drives and place them in any Windows Server to read them.

Why does RAID5 need at least 3 disks but not 2?
