Hey, i am currently trying to create a new raid array i have 4x3tb drives i want do something like having 2 and 2 drives mirrored so that i end up whit 6tb usable space. I dont want to do a raid-10 array since i want too have the ability to expand my array. i currently have a LSI MEGARAID SAS 9240-8I any suggestions?

 

 

Thanks for the help

You can expand a RAID 10 by adding two more identical drives.

Did not know that everywhere else i have read it says the raid-10 arrays cant be expanded.

You most definitely can. You just can't throw a single new drive in, you have to add two drives.

nope...it will combine 2 drives together and other 2 drives together and will mirror on one combination giving u 6gb usable and rest mirrored...

You just described RAID 10.

RAID 1 with 4 drives means data is mirrored across all 4 drives. Useable capacity is that of 1 drive, so 3TB.
