no
yes

How data is distributed to disks in a RAID5

data is divided into blocks of the same size and then blocks are written to the disks
in contiguous streams
data is divided into blocks of different size and then blocks are written to the disks

How data is distributed to disks in a RAID0

in contiguous streams
data is divided into blocks of different size and then blocks are written to the disks
data is divided into blocks of the same size and then blocks are written to the disks

RAID is short for
