How to Recover Data from RAID 1 Disk with Raid 1 Recovery Software

Everything About RAID 1

RAID 1 refers to an exact copy (or mirror) of a set of data on two or more disks. According to Wikipedia, it seems that the RAID 1 configuration provides parity, striping or spanning of disk space across multiple disks. This is useful when read performance or reliability is more important than data storage capacity. RAID 1 writes two copies of the data simultaneously on two separate drives. This is called a fault-tolerant. When one of the mirrored drives suffers a mechanical failure such as spindle failure or does not respond, the remaining drives will continue to function. The RAID 1 configuration is performed either by a hardware RAID controller or performed in software. It is suited to applications requiring high fault tolerance at a low cost and where a duplicated set of data is more secure than using parity. RAID 1 is popular for accounting and other financial data. It is also commonly used for small database systems, enterprise servers, and home PCs where fairly inexpensive fault tolerance is required.

Advantages

• Fast speed. RAID 1 offers an excellent read-and-write speed that is comparable to that of a single drive.
• Large storage. It’s known that RAID arrays usually consist of two or more disks. RAID 1 has much more storage space than a single drive. 
• Continuous system running. On a computer that contains only one hard drive, if the drive fails, the operating system will stop at once. However, in a RAID array, if a hard disk fails, the system will be able to keep running normally for a certain time. 

Disadvantages

• The effective storage capacity is only half of the total drive capacity because all data get written twice.
• The failed drive can only be replaced after powering down the computer it is attached to. For servers that are used simultaneously by many people, this may not be acceptable. Such systems typically use hardware controllers that do support hot-swapping.

Why You Lost RAID 1 Data

Although it seems that RAID 1 disk can be an ideal tool for storing and backing up data with a high fault-tolerant feature. But when data loss issues happen to the RAID 1 disk or RAID 1 volume, what can you do? Here the following are some major reasons for RAID 1 data loss issues:

• 1. RAID 1 disk failure
• 2. RAID 1 disk rebuild
• 3. Format RAID 1

So how to restore RAID 1 data? When you lost important RAID 1 data in Windows 10/8/7, stop using it immediately. Ane let professional RAID 1 data recovery software to help.

People Also Ask

1. What is RAID recovery?

RAID recovery is the process of data recovery from a RAID array that failed for whatever reason. EaseUS data recovery software is a powerful data recovery tool that can successfully recover RAID data.

2. Can a RAID 1 disk be read on its own?

Yes, most RAID 1 systems create disks that are readable separately when connected to a non-RAID controller. 

3. What is the difference between RAID 0 and RAID 1?

RAID 0 consists of striping, but no mirroring or parity. RAID 1 consists of data mirroring, without parity or striping.

4. Can RAID 1 have more than 2 drives?

Yes, 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.
