Provides options to allocate specific amounts of capacity for each volume (only when creating
multiple volumes on RAID).
Recommended for users who want to precisely control storage management on your Synology
NAS.
Uses all of the available capacity of the selected disks to create a single volume.
Provides better speed and performance.

combining hard drives of different sizes. SHR
volumes consisting of two or three hard disks
provide 1-disk fault tolerance, while SHR
1-2
volumes consisting of four or more hard disks
can provide 1- or 2-disk fault tolerance.
A Basic volume is created with one hard drive
as an independent unit. When creating a Basic
0
volume, you can select only one hard drive at a
time.
0 JBOD is a collection of hard drives.
Combining multiple disks to build a storage
space, RAID 0 offers Striping, a process of
0 dividing data into blocks and spreading the data
blocks across several hard drives, but without
safety measures.
