Is RAID 0 or 1 better?

RAID 0 and RAID 1 are two types of configurations or levels that can be set up with an array of independent disks. RAID 0 offers striping, which translates to better performance, but no-fault tolerance or data redundancy. RAID 1, on the other hand, offers mirroring, so the same data is available in two disks.

Is RAID 1 good for backup?

One very important thing to note, RAID 1 is not a backup in and of itself. Although RAID writes data to two disks simultaneously, it is not a backup. If your operating system or software, rather than the hard disk, corrupts your data, this corrupted data is sent to both disks and simultaneously corrupts both drives.

Can I create a RAID 1 without losing data?

Many RAID solutions format a disk when constructing a RAID or adding a new disk. Desktop versions of Windows Windows have a built-in software RAID capability which will attempt to preserve your data during conversion. However, you should still back up your data in case something goes wrong.

Does RAID 1 mirror operating system?

RAID 1 and RAID 10 are both mirroring technologies that use half of their available drives for data, but the main difference between them is the number of available drives.

What happens if I reset disks to non raid?

Member disks in a raid set will often hold reference info that lists all of the other disks in that set. This is to aid in config and rebuild work. When you 'reset disks to non-raid' you delete this info. Whenever you do 'maintenance' on a raid set, you had better have a full backup available.

Can you add RAID 1 later?

Yes, you CAN migrate your single drive volume to a 2 drive RAID1 volume at a later point.

Can you raid an existing hard drive?

You can either set up a RAID configuration with two fresh hard drives or with your existing hard drive and an empty drive that is as large as or larger than your existing drive. At the very least, you'll probably need to install one new hard drive, which we've already covered in detail.

Can you change raid without losing data?

Storage pools can be changed from one RAID type to another without losing existing data. For example, you can create a RAID 1 storage pool on your Synology NAS and later change it to RAID 5 if you install more drives.
