Thinking about Raid 10

IInuyasha74 · Nov 29, 2013

Hello Everyone,

I am thinking about setting up a RAID 10. I am getting a new Hybrid HDD for my laptop, and thinking to just add the old 1TB inside of it to my desktop.

If I do, I am thinking about doing a RAID 0 between a 2TB and the 1TB. Then turning it into a RAID 1 with my 3TB.

I am thinking to just use Windows Disk Manager to set this up.

My questions:

Will I first need to set up the RAID 0, and then the RAID 1, or will there be another option for just doing a straight RAID 10?
Is there a better program for setting this up?
Will any step of this remove the data off of the disks?

Thanks for the help.

If you decide to software raid all that i can guarantee you it will fail. Only viable option is to get a dedicated hardware controller

You set up raid 10 as a proper solution in a planned way. You cannot and never combine raid 0 and 1. In a datacentre solution with decent hardware controllers you have more options, but on the client side you have not without costly addon cards. Either you set up raid 5 or 10 or 0 from start, or you admit failure on desktop

And ofc Raid 1

Why do you think it will fail right out in software? The option exists and has for many years, it cannot be complete a fail.
Though I could just use the BIOS and set it up also if the software is less stable.

Well I am going for RAID 10 and have a plan for setting it up, I am just not completely sure which order it goes in, but if I understand you correctly you just go straight into RAID 10 and define it at that point, not just set it up one piece and then another.

raid 0 between a 2tb and a 1tb would yeild a 2TB raid0 array (it uses the smallest sized drive* the number of drives in the array so 2*1tb=2tb)

raid 1 with the 3tb drive and the 2tb array would yield a 2tb raid01, not a raid10.

popatim :

Oh I see that now, so RAID 0 will not work. Seems a big limitation in the design. I thought it added any number of drives of any size together for the sake of acting like one larger disk drive. Owell.

I was hoping it was able to see the 1TB and the 2TB as a 3TB drive so I could run a RAID 1 for back up purposes without having to drop down to 2TB. I guess it is not possible though.

Thank you for your help.
