RAID Arrays Guide
Number of drive bays
The number of drive bays determines the maximum number of hard drives that can be installed in the RAID array. This can have a significant impact on the storage capacity and scalability of the system. For example, the Synology DS1819+ is a popular RAID array that offers eight drive bays, allowing for up to 144TB of storage capacity. Another option is the QNAP TVS-872XT, which offers eight drive bays as well, and supports up to 112TB of storage capacity. For larger storage needs, the NetApp AFF A200 offers 24 drive bays in a compact form factor, allowing for up to 367TB of storage capacity. When choosing a RAID array, it's important to consider the number of drive bays based on your current storage needs and future scalability requirements.
Supported RAID levels
Different RAID levels offer varying levels of data redundancy, performance, and capacity. For instance, the Synology DS918+ NAS offers built-in support for RAID levels 0, 1, 5, 6, and 10, providing a flexible range of options for different use cases. It also supports the more advanced SHR (Synology Hybrid RAID) and SHR-2 (Synology Hybrid RAID 2) configurations that optimize capacity utilization across differently sized drives.
Another popular option is the QNAP TS-453D-8G NAS, which primarily caters to small businesses and prosumers. It supports RAID levels 0, 1, 5, 6, 10, 50, 60, and JBOD (Just a Bunch of Disks). This wide range of RAID levels allows for a versatile array of configurations based on specific requirements. Moreover, both the Synology and QNAP NAS arrays offer hot-swappable drive bays, ensuring easy maintenance and replacement of drives in case of failure or capacity expansion.
Data transfer rate
This refers to the speed at which data can be transferred to and from the storage drives in the array. A higher data transfer rate is desirable as it allows for quicker access to stored data.
In the market, there are several options available with varying data transfer rates. For users seeking optimal performance, enterprise-grade RAID arrays like HPE Smart Array P408e-p SR Gen10 and Dell PERC H830 are excellent choices. These RAID arrays support high-speed data transfer rates of up to 12 Gb/s and are designed to handle heavy workloads efficiently. Alternatively, for small businesses or home users looking for a cost-effective solution, entry-level RAID arrays like Promise Technology Pegasus32 R4 and Synology DiskStation DS920+ offer solid data transfer rates of up to 10 Gb/s while still providing reliable storage capabilities.
Compatibility with operating systems
Not all RAIDs are compatible with every operating system, so it is crucial to ensure that the chosen RAID is supported by your desired OS. For instance, the WD 16TB My Cloud Home Duo Personal Cloud is compatible with Windows 10, Windows 8, and macOS 10.13 or later. Similarly, the QNAP TS-453Be-2G-US 4-Bay is compatible with various operating systems such as Windows 7, 8, and 10, macOS, and Linux.
Different products in the market cater to specific operating systems. Some manufacturers focus on Windows-compatible RAID arrays, such as the Buffalo LinkStation 220 4TB which is designed specifically for Windows operating systems, while others offer broader compatibility. For example, the Drobo 5C: 5-Drive supports Windows and Mac operating systems, providing more flexibility for users working across multiple platforms. Remember to take into account your specific operating system requirements to choose the RAID array that best suits your needs.
Interface type (e.g., USB, Thunderbolt, eSATA)
USB, Thunderbolt, and eSATA are some of the most common interface types used today. USB 3.0, for example, offers high data transfer speeds of up to 5 Gbps, making it suitable for quick backups and file transfers. A good example of a RAID array with USB 3.0 interface is the WD My Book Duo, which provides storage capacities up to 28TB and RAID support for data redundancy.
On the other hand, Thunderbolt interfaces, such as Thunderbolt 2 and Thunderbolt 3, provide even faster data transfer speeds, making them ideal for professional content creators or users who work with large files. The LaCie 2big Thunderbolt 3 is a great example of a high-performance RAID array that utilizes Thunderbolt 3 technology, allowing for lightning-fast data transfer speeds of up to 440 MB/s and offering multiple RAID configuration options.
Alternatively, eSATA interfaces offer a combination of high data transfer speeds and compatibility with both Windows and Mac systems. They are known for their reliability and are often found in enterprise-level RAID arrays. The Drobo 5D3 is an excellent choice for those looking for an eSATA RAID array, providing support for up to five hard drives and offering flexible data protection options.
The interface type plays a significant role in determining the speed and compatibility of RAID arrays. USB, Thunderbolt, and eSATA are just some of the options available, each catering to specific needs and requirements.

Drive type (e.g., HDD, SSD)
Drive Type (HDD, SSD):
The choice of drive type, whether it be Hard Disk Drive (HDD) or Solid State Drive (SSD), is an important consideration when selecting a RAID array. HDDs are known for their large storage capacities and relatively lower cost per gigabyte. They rely on spinning platters and mechanical moving parts to access data, which can impact their read and write speeds compared to SSDs. If you prioritize cost-effectiveness and need ample storage space for large files, consider options like the Seagate BarraCuda HDD or the Western Digital Blue HDD.
On the other hand, SSDs provide impressive performance, lightning-fast data transfer speeds, and enhanced durability due to their lack of moving parts. With no mechanical components involved in data access, SSDs offer accelerated boot times, faster file transfers, and reduced latency. While they may come at a higher price point than HDDs, the performance gains can be well worth it depending on your needs. Notable options in this category include the Samsung 870 EVO SSD and the Crucial MX500 SSD.
Scalability (ability to add drives later)
RAID arrays that offer flexible expansion options can accommodate future storage needs without the need for system downtime or data migration. One such example is the 'Synology DS1019+', a 5-bay NAS that supports up to 210TB of storage when using expansion units. This makes it an excellent choice for small businesses or power users looking for a solution that can grow with their data requirements. Another option is the 'QNAP TS-873U-RP', a rackmount NAS designed for IT departments and businesses in need of high-performance and scalability.

This software allows for easy configuration, monitoring, and management of RAID arrays.
It's worth noting that some RAID array manufacturers also offer their own backup software. For instance, Synology DiskStation NAS devices come equipped with the highly-rated Synology Hybrid RAID (SHR), offering their own backup software alongside advanced data integrity optimizations. For those seeking a more advanced and scalable solution, Drobo offers their proprietary BeyondRAID technology, which is compatible with the intuitive Drobo Dashboard software, providing flexible storage options for both data protection and availability.
Fault tolerance
When choosing a RAID array, one of the key factors to consider is fault tolerance. Fault tolerance refers to the ability of a RAID system to protect data and continue operating even if one or more hard drives fail. This is crucial for ensuring data integrity and minimizing the risk of data loss.
There are several RAID levels that offer different levels of fault tolerance. RAID 1, for example, is a basic mirroring level where data is replicated across two drives, so if one fails, the other contains an exact copy. For higher levels of fault tolerance, RAID 5 and RAID 6 are good options. RAID 5 requires at least three drives and distributes parity data across all the drives, allowing for continued operation even with a single drive failure. RAID 6, on the other hand, requires at least four drives and offers even greater redundancy, as it allows for the failure of two drives while maintaining data integrity.
When considering fault tolerance, an excellent choice is the 'ZyXEL NAS326'. It supports both RAID 1 and RAID 5 options, providing users with the flexibility to choose their preferred level of redundancy. Additionally, it features hot-swappable drive bays, allowing for easy drive replacement without interrupting data access.
