So far, we have seen the two RAID implementations and the advantages and disadvantages of each. So, which of the two is better? Hardware vs.

Thus, these are the advantages and disadvantages of a software RAID.

Highly vulnerable to viruses, unprotected at boot, and creates data integrity issues due to system crashes.

Replacing a failed disk is a complex process.

Works well only on a single type of operating system, so it can’t be implemented for disks that are shared by different operating systems.

Tends to be slower since it shares the processing capacity of the operating system.

Reconfiguring RAID levels is possible without any restrictions.Ī software RAID comes with its share of disadvantages too.

The same RAID driver can be implemented across many systems that use the same operating system.

Some of the key advantages of software RAID are: The RAID software communicates with the disks through local interfaces and adapters and tends to have higher levels of compatibility with different systems. Software RAID is an implementation that uses the capabilities of an operating system through a RAID software or driver to implement RAID. Thus, these are the advantages and disadvantages of a hardware RAID.

When the RAID controller fails, you need to replace it with a similar controller to ensure no disruptions to your work.

More expensive to implement as you have to invest in new hardware equipment.

It can run in the write-back mode provided it has a battery.

Protects against data loss or corruption that may occur when power is interrupted during a data backup.

Gives the flexibility to add any RAID configuration that may otherwise be hard to implement using just the motherboard.

Less strenuous on the system during backup and recovery.

Greatly improves system performance, especially in legacy systems with limited capacity for improving processing power.

Some of the advantages of a hardware RAID are: Now that we have a good idea about hardware RAID, let’s see its advantages and disadvantages. Also, controller chips designed for IDE systems don’t work on SCSI systems, though major manufacturers like Intel develop some RAID controller versions that work well for all types of disks. For example, a RAID controller designed for RAID 0 implementation will not work well on RAID systems designed for fault tolerance. It’s important to note that RAID controllers score lower on flexibility.

Obviously, they are more expensive and more difficult to install when compared to a bus-based installation. Card-based and intelligent controllers: These are mostly for high-end systems and are typically installed in a separate box as they come with dedicated processors.Bus-based: These controllers come with the motherboard for the most part and are used for controlling the lower-end RAID levels.In a hardware implementation, there are two types of RAID controllers, namely, The main role of a RAID controller is to manage these independent disks and present them to the computer as one or more logical units. In some cases, these RAID controllers are smaller versions of computers since they come with dedicated processors to perform their roles. These RAID controllers physically control the RAID array and support all RAID levels and custom configurations. Hardware RAIDĪ hardware RAID is an implementation where all the disks connect to a piece of hardware called the RAID controller that’s inserted in a PCI slot in the motherboard. In this article, let’s take a detailed look into what hardware or software RAID is, including the advantages and disadvantages of each, and we’ll evaluate which of the two is better for you. For an overview of RAID levels, check out our recent story here at TechGenix. This grouping of disks into logical arrays can be achieved through hardware or software implementation. Redundant array of independent disks (RAID) is a technique to virtualize independent disks into one or more arrays for improved performance, capability, fault tolerance, and reliability.
