RAID 0, explained

[THE16THPHANTOM]

nice axplaining. 

[Kg277]

All your files are belong to us!

@Kg277:

:-P

[Kg277]

I would too!!

[Matticitt]

All your files are FUCKING GONE !

if i have 2 7200 rpm drives, and i put them in raid 0, will i get 14400 rpm speeds?

[Matticitt]

@gisforjesus no...

[shadowglaive999]

The best instructional video I've seen. Great putting this up

@shadowglaive999:

Thanks, glad you enjoyed it. :)

[sn0le]

@shadowglaive999:

Glad you liked it. :)

[ttimefifty1]

you talk very slowly.....

[TekkSpekk]

does the capacity of the drives have to be the same?

[sn0le]

@TekkSpekk:

No, but check the infobox of the video where I added an axplanation about it. :)

[Cmyk7s]

I accidentally delete my Software RAID 0 , i don't have raid card , I need help to rebuild my raid , its 3X2 TB , Please help me , i ask Apple and they ignoring my calls

[taste1337]

Do you need to have the same 2 hard drives to run RAID0?

[Matticitt]

@taste1337 No, but it's strongly recommended.

[MrAvatar9999]

noted, thank you for your prompt reply.

by the way, can I image my RAID HDD ? which software do you recommend ?

[sn0le]

@MrAvatar9999:

It should be no problem making images of a RAID array.

The OS sees it as a single volume/drive/disk.

I use DriveImage XML when I need to make images of drives.

But there are plenty others that probably are better.

[MrAvatar9999]

sorry for my poor language.

If I install the operating system and applications in harddisk(2 nos of harddisk) that configue with RAID 0 ( these harddisk only store operating system and applications) and all my data store at anathor harddisk. so total I hace 3 nos of harddisk. Do you think this is good set-up?

My ideal is to have fast processing speed. Please advice. Tq

[sn0le]

@MrAvatar9999:

No worries mate.

Running your OS and apps on a RAID0 will definetly increase read and write speed for your OS.

Your machine will boot quicker and apps load faster.

Storing your data on a separate drive will be better than having it on the RAID0 array, since RAID0 has no redundancy.

I know alot of people that use SSD (or 2 SSD's in RAID0) for OS and apps, and a HDD for data.

Some people even have data on a RAID1 or RAID5 array.

Basically it comes down to how much you can spend.

[MrAvatar9999]

hi, if i install OS in 2 nos of HDD RAID 0 and data in another HDD will this help in term of processing speed ? Thank you in advance for yor reply. :)

[sn0le]

@MrAvatar9999:

I'm sorry, but I didn't quite understand your question.

[dragonhandss]

i understand now so is the raid 0 better than raid 1 or wat??

[sn0le]

@dragonhandss:

What is best depends on your storage needs.

If you need high performance and alot of space, RAID 0 is better.

The downside is that if one HDD crashes, you lose everything on both drives.

So the data stored on a RAID 0 array should not be important data.

If you need good performace, and it is crucial for you that the data is safe, RAID 1 is better.

The downside is that it is more costly pr GB since you use 2 HDD's to get the capacity of one HDD.

[CometUK]

Nice explaniation, helped me further understand it easily, alot easier than trying to learn from wikipedia lawl :)

[sn0le]

@CometUK:

Thanks. Glad my video helped you. :)

[panflutelistener]

I got a question, would it work with disks of different RPM's? say one of 7200 and another one of 10k ? or do they have to be the same RPM. I know they don't have to be the same size but I don't know about the speeds.

[sn0le]

@panflutelistener

It should work, but the arrays performance will be limited to the slowest drive.

I've seen people warn against using HDD's with different RPM's because they mean it can cause problems.

Not sure if that is fact or fiction.

I've never tested it my self, I run only 7200 rpm HDD's.

If you have a 10k and a 7,2k rpm HDD, the best would probably to buy another 7,2k rpm HDD and use that in the RAID.

And then maybe have the OS on the 10k HDD? ;)

[kmsdhaka]

Thank you very much for your nice explanation. It helps many people.

[sn0le]

@kmsdhaka

Thanks for the feedback.

Always good to hear that my vid has helped people understand this techno-babble. :)
