RAID 0 is a data storage virtualization technology that combines multiple physical disk drives into a single logical unit to improve performance. This calculator helps you determine the total storage capacity and performance of your RAID 0 array.
What is RAID 0?
RAID 0 (Redundant Array of Independent Disks) is a disk array configuration that combines multiple physical drives into a single logical unit. It's designed to improve performance by striping data across all drives in the array.
RAID 0 is not fault-tolerant - if one drive fails, all data in the array is lost. However, it offers the highest read and write performance among all RAID configurations.
How RAID 0 Works
In RAID 0, data is divided into blocks and these blocks are distributed across all drives in the array. This process is called striping. When data is read or written, it's accessed from or written to multiple drives simultaneously, which significantly improves performance.
Example
If you have two 1TB drives in a RAID 0 array, the total storage capacity will be 2TB. When you write data to the array, it's split into blocks and written to both drives simultaneously.
RAID 0 is ideal for applications that require high performance but can tolerate data loss, such as video editing, gaming, or temporary storage.
RAID 0 Formula
The total storage capacity of a RAID 0 array is calculated by multiplying the number of drives by the capacity of each drive:
Total Capacity = Number of Drives × Capacity per Drive
For example, with 4 drives each with 2TB capacity:
Total Capacity = 4 × 2TB = 8TB
The performance of a RAID 0 array is determined by the number of drives in the array. More drives mean better performance, but also higher risk of data loss.
RAID 0 Pros and Cons
Pros
- High read and write performance
- Simple to implement
- Uses all available storage space
Cons
- No data redundancy - single drive failure causes total data loss
- Not suitable for critical data storage
- Performance degrades as more drives are added
FAQ
RAID 0 requires at least 2 drives to function. With only one drive, it's not considered RAID 0.
Yes, you can add more drives to an existing RAID 0 array, but you'll need to recreate the array and migrate data, which can be time-consuming.
RAID 0 is not recommended for system storage as it lacks data redundancy. Consider RAID 1 or RAID 10 for system storage.
