Would you like to know how to configure your Synology NAS for optimal performance and data security?
The Synology RAID Calculator can help! This handy tool offers an estimate on the space utilization with various mixed HDD configurations and RAID types. Keep in mind that the actual HDD size will be affected by the system partition and can vary between vendors, so the values calculated may differ from the actual results. But this is a great place to start when making your decision. Let's take a closer look at how it works!
The RAID Calculator
The RAID Calculator is easy to use. Just enter the number of drives you want to use, the capacity of each drive, and the RAID type you are considering. The calculator will then provide you with an estimate of how much space the configuration will use and how secure it will be. You can also view a breakdown of the estimated disk usage for each RAID type. This can help you make an informed decision about which option is best for your needs.
So what are some of your options? Here's a look at the most common RAID types:
RAID 0
This configuration uses striping, which spreads data evenly across all disks in the array. It offers high performance and speed but no redundancy. If one disk fails, all of the data in that array will be lost.
RAID 0+r
This is a RAID-0 configuration with an additional level of protection called mirroring. It means that if one disk fails, there's another copy available on another drive so you don't lose any data. However, it will result in slower performance and a lower capacity than RAID-0 alone.
RAID 0+r(n)
This is similar to RAID-0, but with more redundancy and fault tolerance through multiple levels of mirroring. It can be configured for up to four drives in an array and offers better overall performance than other types such as RAID-0+R or RAID-0+R(n) with only one level of mirroring.
RAID-I
This RAID type is also called disk duplexing and uses striping along with parity to provide redundancy. If one drive fails, the data can be rebuilt from the remaining drives. However, it offers less performance than RAID-0 and uses more storage space.
RAID-NI
This RAID type is also called disk duplexing and uses striping along with parity to provide redundancy. If one drive fails, the data can be rebuilt from the remaining drives.
RAID-X
This RAID type combines mirroring and XOR to create a redundant array of disks that will allow for faster performance than other types such as RAID-0+R or RAID-0+R(n). It offers more flexibility in how many drives can be used and uses less storage space, but requires additional software.
RAID-Z
This type allows you to have multiple levels of redundancy by combining mirroring with XOR to create a redundant array of disks. It is similar to RAID-X but can be used with more drives and offers better performance.
There are also other options such as JBOD (Just a Bunch Of Disks) which allows you to use individual drives without any type of RAID protection, or Synology's own SHR (Synology Hybrid RAID) which is a proprietary RAID type that offers increased flexibility and easier management.
