Chapter 2: Quick Start Guide Chapter 2: Quick Start Guide This chapter provides an overview of the initial configurations of Synology DiskStation Manager (DSM). To help you get started with your Synology NAS, perform the following instructions about drive setup, OS installation, storage initialization, and several built-in services of DSM management. 2.1 Install drives As a data storage server, Synology NAS needs at least one 3.5" or 2.5" drive to ensure functionality. For detailed information on drive installation, please refer to the Hardware Installation Guide via Synology's Download Center. Back up drives before installation If your drive comes from an old Synology NAS, please follow the instructions in this article to perform drive migration. The migration procedures mentioned in the article will help you keep most of your data. However, we strongly recommend that you back up data on the original Synology NAS, from which drives are moved, to avoid accidental data loss. If your drive does not come from a Synology NAS that contains data, you need to back up data before the installation because the system will format drives and erase all the existing data during the installation. Understand RAID types After the drive installation, you should set up a RAID array to add extra security and redundancy to your storage space. This section gives you a brief introduction to the RAID technology and the difference between each RAID type. RAID (Redundant Array of Independent Disks) is a data storage technology that allows multiple independent drives to be combined into a RAID array for data redundancy and performance improvement. In a RAID array, the same data will be stored in different places across multiple drives to reduce the risk of data loss caused by a drive failure. Moreover, the RAID setup can boost the read-write performance because data will be striped across drives under certain RAID configurations. Different RAID configurations provide different levels of redundancy and performance. The following is an overview of the RAID types supported by Synology NAS: 02

Chapter 2: Quick Start Guide
This chapter provides an overview of the initial configurations of
Synology DiskStation Manager
(DSM)
. To help you get started with your Synology NAS, perform the following instructions
about drive setup, OS installation, storage initialization, and several built-in services of DSM
management.
2.1 Install drives
As a data storage server, Synology NAS needs at least one 3.5" or 2.5" drive to ensure
functionality. For detailed information on drive installation, please refer to the
Hardware
Installation Guide
via Synology's

.
Back up drives before installation
If your drive comes from an old Synology NAS, please follow the instructions in
this article
to
perform drive migration. The migration procedures mentioned in the article will help you keep
most of your data. However, we strongly recommend that you back up data on the original
Synology NAS, from which drives are moved, to avoid accidental data loss.
If your drive does not come from a Synology NAS that contains data, you need to back up data
before the installation because the system will format drives and erase all the existing data
during the installation.
Understand RAID types
After the drive installation, you should set up a RAID array to add extra security and
redundancy to your storage space. This section gives you a brief introduction to the RAID
technology and the difference between each RAID type.
RAID (Redundant Array of Independent Disks) is a data storage technology that allows multiple
independent drives to be combined into a RAID array for data redundancy and performance
improvement. In a RAID array, the same data will be stored in different places across multiple
drives to reduce the risk of data loss caused by a drive failure. Moreover, the RAID setup can
boost the read-write performance because data will be striped across drives under certain
RAID configurations.
Different RAID configurations provide different levels of redundancy and performance. The
