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.


  • 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. 


  • 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. 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?

Frequently Asked Questions

1. Why choose EaseUS Data Recovery Wizard?

"EaseUS Data Recovery Wizard is the best we've seen. It's far from perfect, partly because today's advanced disk technology makes data-recovery more difficult than it was with the simpler technology of the past, but it's fast and efficient..."PCMag

"The first thing you'll notice about EaseUS Data Recovery Wizard Pro is that its interface is very clear and uncluttered, with only a small collection of self-explanatory controls. You won't find lots of extra options hidden in a system of hidden menus, either; what you see really is what you get."techradar

"Recover lost files, even after deleting a partition or formatting your drive."Macworld

2. Why cannot I recover 2GB data for free?

It is recommended to check the version installed is Free or Trial because they are different versions.

Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.

3. Why cannot the recovered files be opened?

A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.

If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.

4. Why isn't it suggested to recover the files back to the original drive?

The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.

5. How can I check whether my data is recoverable or not before purchase?

The Free version helps you save 2GB files, so verify the recovery quality of our product before purchase.

6. How long does it take to scan the drive?

It strongly depends on the capacity of your hard drive and the performance of your computer. As reference,most drive recoveries can be completed in around 10 to 12 hours for a 1-TB healthy hard drive in general conditions.
