Hi all.
lets say i have 4 disks of 2TB each. configured in RAID 5.
so in the raid config i see 1862.50 X 4 disks.
How much space the raid controller is taking from each disk ?

so in the end i have free storage 3 X 1862.50 ? (1 is off for RAID..) - 5587 GB ?

And if i will expand the raid with a fifth disk. it will expand my hardisk size to 5587+1862.50 ?

thanks.
