Can RAID drives be different sizes?

Can RAID drives be different sizes?

For a normal RAID, you can RAID different sized drives together just like you can with same-sized drives. The only “gotcha” is that the RAID will treat all drives in the array as if they were all the same size as your smallest drive.

Can you mix drive sizes in a RAID 5?

You can add larger disk drives, but only the smallest size will be used. If you mix 36 GB, 72 GB and 146 GB drives in a RAID 5, only 36 GB of each disk will be used (72 GB useable capacity).

Do all RAID 5 drives need to be the same size?

Do all drives have to be the same model and capacity for a RAID 5 array? The short answer is No, the drives don’t have to be exactly the same. The longer explanation is that for compatibility reasons, we usually recommend using the same model.

Can you mix and match hard drives in RAID?

The short answer is no – especially for software RAID configurations, they do not have to be the same in any way. They do not have to have the same speed, interface, cache size, or medium (magnetic disk/SSD).

Can you RAID 1 with different size 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 two different hard drives?

A Redundant Array of Independent Disks (RAID) puts multiple hard drives together to improve on what a single drive can do on its own. Depending on how you configure a RAID, it can increase your computer’s speed while giving you a single “drive” that can hold as much as all of the drives combined.

How many drives do I need for raid?

You need at least 2 drives for a RAID 1 array. RAID 1 offers excellent read speed and a write-speed that is comparable to that of a single drive. In case a drive fails, data do not have to be rebuild, they just have to be copied to the replacement drive. RAID 1 is a very simple technology.

Can different hard disks be used to build a raid?

RAID is a technology that is used to increase the performance and/or reliability of data storage. The abbreviation stands for either Redundant Array of Independent Drives or Redundant Array of Inexpensive Disks, which is older and less used. A RAID system consists of two or more drives working in parallel. These can be hard discs, but there is a trend to also use the technology for SSD (Solid State Drives). There are different RAID levels, each optimized for a specific situation.

Do you need raid with multiple drives?

The primary advantages of a RAID array are data security, thanks to the storing of duplicate copies of your data on multiple drives (known as mirroring), and speed, which is the result of writing and then reading data from multiple drives at once, taking advantage of the maximum data transfer rate of each drive in a process known as data striping.

Do RAID drives need to be exactly the same?

Do all drives have to be the same model and capacity for a RAID 5 array? The short answer is No, the drives don’t have to be exactly the same. The longer explanation is that for compatibility reasons, we usually recommend using the same model. If a certain drive is already compatible and works fine, using four of the same model will cause the
