RAID with SSD and HDD: Move to Boost Your RAID Performance
Here you will find out:
- is there any advantages of SSD usage for RAID
- how you can combine SSD and RAID
- how to restore the data from SSD RAID
Are you ready? Let's read!
Benefits of SSD for RAID
The idea of RAID with SSD can be quite good, but it has significant shortcomings that make such a device not so attractive as, for example, HDD RAID. Although SSDs have a significantly longer life, they still decline.
And in this case, replacing the disk will cost several times more than replacing the HDD.
Combine SSD and RAID
SSD can be connected to RAID 1, and in this case, if one drive fails, then the data will be in integrity. Using such an array, you can achieve high enough performance, which is also certainly pleasing.
However, there are also negative features of this merger:
- It is possible to use only half of the total free space.
In addition to RAID 1, you can use SSD in RAID of other varieties. In this case, it will then be possible to choose priorities; for example, some arrays increase productivity, others are more fault-tolerant, etc.
SSD RAID advantages in front of RAID HDD
SSD RAID array will always be faster than an array with a hard drive: access to files will be instantaneous; therefore, performance will not let you down.
Also, using SSDs, energy will be consumed by almost half less and additional equipment for cooling processes will not be required, since solid-state drives hardly heat up.
Of course, do not forget that hard drives are very delicate, and some mechanical and physical damage can damage the rotating head, which will destroy the drive. In this regard, SSD RAID is more reliable.
SSD RAID with different array types
If you decide to use these disc arrays to create an array, you should be aware of the types of RAID in order to responsibly and correctly approach this issue.
The data will remain where it is and be waiting for you on another healthy disk thanks to RAID 1's redundancy. The acting, though, is a tad dull in this instance.
SSD RAID 5 is a minimum of three drives that use data striping with parity bits. Here the data is protected as much as two disks can break at the same time.
SSD RAID 6 - Uses 4 or more drives and uses striping and double parity. This array also has maximum fault tolerance and relatively high performance. However, the cost of such an array will not be small.
SSD RAID 10 will probably be the best solution since, here, the mirroring method is used to increase fault tolerance. At the same time, productivity will be at a high level.
Both RAID 6 and RAID 5 are not recommended for solid-state drives since they require many write operations due to their parity mechanism. And an SSD has a limited write cycle and quickly becomes unusable.
What about SSD RAID data recovery?
How to recover missing information from a damaged RAID SSD. Now is the time to decide on tactics to restore this data. Do not frantically search for relevant forums on the Internet; you can download the DiskInternals RAID Recovery application and restore all the missing information step by step.
The application returns data of any format from damaged RAID 0, RAID 1, RAID 4, RAID 5, 50, 5EE, RAID 6, RAID 60, etc. It supports Windows 7, 8, 10, Vista, or Windows Server 2003-2019. The recommended software is equipped with a wizard with step-by-step instructions and a preview function of found files at no cost. After you are convinced of the transparency and quality of the application, you can purchase a license for this application and export these recovered files to a secure storage device.
The application professionally performs its task and has the highest results, as evidenced by the numerous positive reviews of users and customers.
