RAID stands for redundant array of independent disks. RAID contains the word array, and the two terms are often used interchangably. An array is a combination of two or more physical disks that are presented to the operating system as a single device.
Disks are combined into different RAID configurations known as RAID levels. The RAID level you choose depends on which storage attributes are most important to you:
| Capacity | The total amount of data you can store. |
| Performance | The speed at which data is copied. |
| Protection | The number of disks that can fail before data is lost. |
Your LaCie Rugged RAID Shuttle can be configured as RAID 0 or RAID 1. Each RAID level has its own advantages:
| RAID level | Capacity | Protection | Speed | Factory default |
|---|---|---|---|---|
| RAID 0 | 100% | None | Excellent | Yes |
| RAID 1 | 50% | Excellent | Good | No |
You can manage RAID levels and formatting using LaCie RAID Manager, a comprehensive tool for all of your RAID-compatible devices.
