Can you RAID 1 with different size drives?

In a RAID 1 configuration, the size of target disk must be greater or equal to the one of the source disk. Therefore the capacity of the array will be same as the one of the smallest size in the group. The only exception is a spanned volume.

How much space does RAID 1 take?

With two 4 TB drives, RAID 1 gives you 4 TB storage. RAID 5: This setup requires at least three drives, and uses block-level striping (as in RAID 0) and distributed parity. This means that the data is written in such a way so if one drive is damaged or fails, you can still recover all your data.

What is the minimum disk for RAID 1?

two disks
A minimum of two disks is required for RAID 1 hardware implementations. With software RAID 1, instead of two physical disks, data can be mirrored between volumes on a single disk.

Can you add disks to RAID 1?

You can add one or more disks to a RAID group in the storage pool. Important: Adding disks to a RAID 1 group changes the RAID type of the group to RAID 5. To expand a RAID 50 or RAID 60 pool, every sub-group must be expanded with the same number of disks.

Does RAID 1 require identical drives?

Must hard drives in a RAID array be identical? No. It is perfectly valid to use hard drives from different manufacturers, model numbers, sizes, and rotational speed (spindle speed or RPM).

Can you RAID a SSD and HDD?

Even though it’s possible to set up a RAID with SSD and HDD, the outcome will be an array performing only as fast as the slowest drive. Mixing RAID with SSD and HDD will lower the bar if you consider any RAID configuration, whether striping, mirroring, or parity, simply because an HDD can do only so much.

Does RAID1 need identical drives?

Can you create a RAID1 without losing data?

It depends on your RAID solution. 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.
