Intel Matrix Storage Manager RAID-5 add 4th hard drive question

[idata]

Intel® ICH7R South Bridge:

*4 x Serial ATA I/II 3.0Gb/s with Intel® Matrix StorageTechnology with RAID 0, 1, 5, 10 support

in Intel Matrix Storage Manager option ROM utility (Ctrl-I):

RAID 5

3x250Gb =~500 it's ok

3x1Tb = ~1800 GB

4x1Tb = ~ 764,5 GB

Is this a limitation of the controller? or BIOS? or motherboard?

ASUS P5LD2-V - + 4x ST31000524NS

Is this a limitation of the controller?

Yes for the ICH7R and making it bootable over 2TB.

That would be 2TB until you get to ICH9R or higher allowing 2-256TB data volume support.

!Note that I also had to install a 64-bit version of Windows, since 32-bit versions have a 2TB per disk limit.

THANK YOU, Peter!

PS mm... and where table of max array sizes on Intel's website?

Note: 2TB is a hardware limitation not just a windows limitation too.

Note2: 2-256TB is possible only if its not a bootable array and windows allows 2TB+

Note3: you can only have a 2TB+ bootable array only if the hardware & windows supports it.
