In recent times, storage virtualization technology is being used to improve the reliability and performance of storage devices. So a RAID technology has been filed in every application, such as servers, desktops, and environments that need a numerous amount of hard disk drives.
RAID can be accomplished via software or hardware. In this article, we will discuss the differences between Hardware RAID, Software RAID, and FakeRAID, as well as their advantages and disadvantages in detail.
RAID, known as Redundant Array of Inexpensive Disks, is a storage technology. It is a configuration of two or numerous hard drives to work as a single unit in the computer system. The main concept of RAID is to provide high-availability installation, which detaches the whole storage of data from system or infrastructure failures.
This technology uses an array of various disks drives which creates a fault-tolerant disks arrangement using mirroring and striping. Mirroring can be explained as storing files on the drives set in the server. These files have been copied identically across multiple drives. Whereas striping stores the split files into several parts which alternate across the disks.
In some of the RAID configurations, both striping and mirroring are used. It saves the properly configured disks arrays from failing, and the general operations will be unaffected so that the users never experience downtime.
There are various RAID levels, but the most popular are RAID 0, RAID 1, RAID 5, and RAID 10. The RAID arrays are popular in drafting NAS or SAN devices.
RAID is a common way to virtualize multiple independent hard disks to increase capacity, performance, and reliability. This technology can be implemented as hardware or software, depending on how you want to distribute your data.
This part will differentiate between RAID implementations with their advantages and disadvantages.
In Hardware RAID, the drives are connected to the RAID controller card inserted in a fast PCI-Express slot in a motherboard. It uses a dedicated RAID controller to manage a raid configuration. With the help of Hardware RAID, the RAID controller configures the virtual disks, physical array and initializes them for use.
Hardware RAID has many other extended functionalities, such as hot-swap disk if anyone single disk fails. It has higher productivity and compatibility. Following are a few advantages and disadvantages of Hardware RAID.
It is implemented at the Operating system level, usually in the form of a modified driver. Software RAID does not use any special hardware to connect the storage devices. However, it increases the overall processing load on a server.
This technology is configured via software on the BIOS level. It is commonly suitable for processing simple RAID 0, RAID 1, and RAID 10. Moreover, RAID level re-configuration is possible in it. Here are a few benefits and drawbacks of Software RAID.
FakeRAID is also known as HostRAID, provided without any additional cost with many motherboards. It is simply a multi-channel disk controller with special BIOS configuration parameters. At the initial stage, the system would load from the controller chip, where it hands the RAID functionality off to the OS driver.
Simply mirror two 1.5 TB drives without the need for an expensive Hardware RAID 5 is becoming a popular option. However, there is no significant performance difference between FakeRAID and Software RAID. Anyways, FakeRAID is more or less Software RAID. Below are the few advantages and disadvantages of FakeRAID.
In our daily routine, there occur several circumstances that result in losing out crucial data. Sometimes you work for hours on a specific task, and it just gets deleted by you or by power loss. In this part, we will teach you the easiest way to recover the deleted data.
Wondershare Recoverit assists in recovering the data which got deleted due to human error or system crash. It recovers data from several storage devices, including recycle bin, hard drive, or a crashed computer. This recovery software helps to back up data and large files in a short time.
The program allows you to restore the data from internal as well external devices. That means you can recover the data from hard drives or USB. Recoverit has an interactive interface, which covers all the details about the software, pricing, and plans.
The tool's preview feature makes the process easy to see what you want and don't want to restore. It offers deep scanning to discover all the data on the selected location. You can avail the customer service in case of any additional queries or problems. Thus, Recoverit is the ultimate solution to recover the deleted or lost data with its advanced features.
Wondering how to use this software for data recovery? Heading towards the step-by-step guide.
Step 1: Select your Location for Recovery
Launch the Wondershare Recoverit software on your device. Then choose a location where you have lost the data. From the given locations on the main interface, select any hard drive, disk, or desktop. Click the 'Start' button.
Step 2: Initialize the Scanning Process
This step initializes the scanning of all files, which takes some time. However, large-size files may take some time.
Step 3: Preview and Recover Lost Data
Once the program has completed the scanning process, you can preview the recoverable files. Mark the files and click the 'Recover' option to retrieve the files back.
The above article has concluded the explanation of Hardware RAID, Software RAID, and FakeRAID. If you are comfortable with initial investments, then you should go for Hardware RAID, else Sofware RAID. Both of these RAID technologies are dedicated controllers for the RAID configurations.
Further, this article has introduced the easiest data recovery solution. Wondershare Recoverit provides advanced features to restore the deleted data due to human errors or system failures. It is the best attractive option if you want a reasonable and easy data recovery solution.
You need a minimum of 2 hard drives for RAID 0 and RAID 1. Whereas, for RAID 5 and RAID 6, you require a minimum of 3 and 4 hard drives, respectively. The number of SSDs and hard drives depends on the type of RAID that you are using currently.
RAID 0 is the fastest type of RAID, but it should be used only for non-critical information because you will lose all data if one drive fails. This is because data is lined on both drives, so the loss of one drive is equivalent to the loss of all of your data.
RAID 0 has the best storage capacity as there is no redundancy and no reason to mirror data. Instead, RAID 0 only lines the data across 2 drives, allowing organizations to take full advantage of all the storage capacity of all drives. However, RAID 0 should not be used for sensitive device data because the failure of even one drive will result in complete data loss.
