A Redundant Array of Independent Disks is a trustworthy data storage system that provides users with high storage capacity and increased performance. RAIDs are usually used when storing large amounts of data is required.
There are various RAID levels designed to serve users with different purposes. Diverse RAID functions are available based on its infrastructure. The system runs on several drives, providing redundancy and fault tolerance.
Traditionally, RAID arrays use HDDs as the main component of their system. Nowadays, solid-state drives take over hard disk drives. Hence, replacing HDDs with SSDs in Redundant Arrays of Independent Disks becomes an option.
SSD RAID vs. HDD RAID
Hard disk drives and solid-state drives have different data storage systems. Therefore, each of these devices has its advantages for users. The same goes when HDDs and SSDs are used in RAID arrays.
HDD and SSD RAID arrays provide users with different benefits and functions. Hence, when choosing one of these media, it is critical to prioritize your objectives.
Performance. Considering both of these storage devices outside the RAID system, we state that SSD provides a higher level of performance than HDD. The same applies to these media in RAID; SSDs are faster due to their structure.
Cost. Because of its complicated structure and higher efficiency, an SSD has a higher price. Considering that hard disk drives provide higher storage capacity for the user, the SSD cost is considered a significant disadvantage.
However, when reviewing maintenance costs, SSDs are more power efficient, which lowers the cost. HDDs require a lot of energy for their moving parts, which results in higher maintenance costs.
Reliability. Solid-state drives have a reliable storage system and face data loss less often than hard disk drives.
Moreover, due to the moving parts and fragile structure, HDDs are susceptible to physical damage, which can result in severe consequences for a whole array.
Unfortunately, SSDs also have drawbacks in their system. These devices have limited read/write cycles, which affects the ability to write data. It is essential to regularly inspect the solid-state drive to understand when this situation can occur.
Hence, when a user needs a reliable and fast device, it is preferable to choose an SSD-based RAID. However, if processing large amounts of data is a requirement, then HDD RAID is a more suitable option.
RAID with SSDs and HDDs Combined - What are the Risks?
There is also an option of combining HDDs and SSDs inside your RAID. However, it is not only complicated but also risky. There are various reasons not to use this method on your array if you want to protect data from any issues.
Hardware Issues
As we mentioned, HDDs have a more fragile data storage system than SSDs. Hence, when some hard disk issue or drive failure occurs, it will affect not only its performance but compromise the performance of SSDs and the RAID itself.
Maintenance Difference
There is a significant difference between SSDs and HDDs, so these devices need a unique approach. Supporting both of them in an array can be time-consuming and costly. Thus, we recommend not combining different kinds of drives.
Inefficient Work
When combining HDD and SSD inside your array, you should consider that the device's speed will adjust to the lowest rate. There is no point in mixing hard disk drives with solid-state drives if it does not provide a user with higher productivity.
Our company does not recommend mixing hard disk and solid-state drives within a RAID system, as it does not provide a user with any advantages. It is better to run your Redundant Array of Independent Disks based on one type of data storage device and focus on its performance.
However, data loss is always possible whether your RAID is running on HDD or SSD. Each of these systems has disadvantages that can result in file inaccessibility. In such a situation, it is better to entrust your RAID to professionals.
