RAID 5 vs RAID 1: which one is the better for you?

Here you will find out:

  • what is the difference between RAID 1 vs RAID 5
  • is there any advantages of RAID 5 over RAID 1
  • is there any data recovery difference

Are you ready? Let's read!

RAID 5 vs RAID 1: configuration differences

RAID 5 vs RAID 1

In RAID 1, the configuration is slightly simpler than in RAID 5.

Here, some hard drives are merged into one by parallel merging: the read/write speed of this array will be the same as that of a single disk since the read/write information is performed on both disks simultaneously.

RAID 5 uses parity striping to distribute information.

The essence of a RAID 5 array is that several disks are combined for striping, and the last disk contains parity bits where the so-called service information is stored, which is used to restore one of the disks in case of failure.

RAID 5 vs RAID 1: read/write possibilities

In RAID 1, the read/write speed will be the same as that of a single disk (maybe a little higher), because the read/write information is performed on both disks simultaneously.

The write speed for a RAID 5 array is slightly lower, as time is spent on calculating and recording a checksum on a separate disk. But the read speed here is at a fairly high level.

RAID 5 vs RAID 1: fault tolerance

In RAID 1 In the event of a failure of one drive, the other continues to function, as there is a duplicate drive or mirror. This is the easiest and relatively inexpensive way to increase fault tolerance.

Here, in RAID 5 data and parity information are split between three or more disks.

Sectors usually fail on disks; complete failure of the entire disk happens less frequently. In a RAID 5 array, in the event of a partial disk failure, data is restored based on the remaining data and parity information automatically and invisibly to the user. However, recovery here is much slower than in RAID 1.

Therefore, the choice of RAID 1 or RAID 5 is up to you!

RAID 5 vs RAID 1: performance difference

Now let's look at RAID 1 vs RAID 5 performance. The performance of RAID 1 is okay, but not great. In order to increase it, you need to use more than two disks.

As for RAID 5, for a long time, it was positioned as a slow array, but over time the disk controllers have changed, and this array can also be considered quite productive.

RAID 5 vs RAID 1: redundancy

Both of these arrays are able to withstand a disk failure, but the read/write speed drops sharply since all operations are accompanied by additional manipulations. However, the file system in RAID 5 will not be as slow as in RAID 1.

Therefore, both arrays can in principle be commended for redundancy.

RAID 5 vs RAID 1: difference in storage capacity

In RAID 1, there are usually two disks and they are always the same size; in fact, half of the total volume will be used.

RAID 5 uses a minimum of 3 disks and one of them is used exclusively for recovery. In this case, ⅔ of the total volume will be used to record information. In this case, the difference between RAID 1 and RAID 5 is obvious: this variant of the array will be more powerful, but more expensive.

RAID 5 vs RAID 1: other comparisons

RAID 1 fault tolerance can be combined with a simple and rapid recovery process: the data simply is copied (but at the same time, the array must be disabled).

In RAID 5, there is good resiliency combined with a monotonous and time-consuming recovery process (however, the data will be available even in the recovery process).

Data recovery differences in RAID 5 vs RAID 1

For RAID 1 - RAID Recovery is the best, but you may do well with simple applications like DiskInternals Uneraser or Linux Recovery. Which one to choose? That's depending on your file system.

For RAID 5, you definitely should use DiskInternals RAID Recovery.

Using the application is very simple despite the rather complicated array configuration. Just select your RAID drive and RAID Recovery will automatically build a RAID array in a few minutes. All recovery stages are automated and the progress and phasing of your actions will be coordinated by the Recovery Wizard. A preview of everything found for you is completely free; this will leave you without a doubt about choosing this application. Purchasing a license is necessary only if you want to save the data found and restore it to another location.

Be sure to take advantage of this unique offer and you never will not be indifferent to it!

Good luck with this process!
