bash + how to combine output values in the same line

Question

we have two array variables:

linux_machines

disks

printf "%s\n" ${linux_machines[*]}

neptun1
neptun2
neptun3

printf "%d\n" ${disks_num[*]} 

4
5
5

how to combine both arrays values so w'll get the following expected results

neptun1 ..... 4
neptun2 ..... 5
neptun3 ..... 5

With bash:

for i in ${!linux_machines[@]}; do echo "${linux_machines[$i]} ..... ${disks_num[$i]}"; done

Output:

neptun1 ..... 4
neptun2 ..... 5
neptun3 ..... 5

I assume that neither arrays has gaps in the field numbering.

paste + printf solution:

linux_machines=("neptun1" "neptun2" "neptun3")
disks=(4 5 5)
paste -d' ' <(printf "%s .....\n" "${linux_machines[@]}") <(printf "%d\n" "${disks[@]}")

The output:

neptun1 ..... 4
neptun2 ..... 5
neptun3 ..... 5

Used below method to achieve the same.

for i in 0 1 2; do echo ${linux_machines[$i]]}" ...... "${disks[$i]}; done

output

neptun1......4
neptun2......5
neptun3......5
