Selection of the best lightning protection system 3 Backup system

Here are six important factors to consider when buying a Thunderbolt 3 RAID storage system.

Hardware RAID vs.Software RAID

Thunderbolt 3 RAID storage comes in two versions: Hardware or software. Hardware RAID uses a built-in hardware RAID controller to manage RAID arrays, configurations, and multiple RAID levels. The RAID controller is built into the RAID enclosure and operates independently of the operating system. This means that there is no extra load on the processor of the PC or server.

Although it can be slightly more expensive, hardware RAID is the best choice if you want to achieve high, sustained performance and save processing power on your PC. It also offers additional features such as hot swapping, which allows you to swap drives faster.

Fortunately, most RAID enclosures in this guide are equipped with hardware RAID controllers. The TerraMaster D8 Thunderbolt 3 RAID drive is the best option for high capacity storage, while the Glyph Atom RAID SSD is the best affordable and portable option.

Software RAID, on the other hand, relies on the processing power of your PC or server’s CPU to manage the RAID configuration. It’s cheap because it only requires a driver and no special hardware, but it puts more strain on your laptop or desktop, which can lead to slow RAID calculations and slow read/write speeds.

Software RAID is ideal if you are on a tight budget. Software RAID enclosures are less expensive than hardware RAID enclosures. And if you have a powerful PC or server processor, you may not even feel the effects of the additional workload.

OWC ThunderBay 8 is the best software RAID array with Thunderbolt 3 interface for demanding workflows and slow-paced businesses, while OWC ThunderBay 4 is ideal for medium and professional users. Both come with SoftRAID software for RAID configuration, layer management and accounting.

RAID level

You can configure different RAID levels/rays depending on your needs and the number of disks available. First, it depends on whether you are looking for performance or redundancy and fault tolerance.

The most common RAID levels are RAID 0, 1, 5, 6 and 1+0 (10).

RAID 0, also known as hard disk striping, divides data into blocks and distributes them among the various disks in the RAID enclosure. By using multiple hard drives to access the same file, higher read/write speeds can be achieved. RAID 0 is ideal for storing non-critical data that needs to be accessed at high speed.

All Thunderbolt 3 RAID arrays in this guide support RAID 0. In fact, Glyph Atom RAID SSDs are offered as a standalone RAID 0 solution. However, RAID 0 offers no redundancy or fault tolerance. If a drive fails, all the data in the RAID array is lost.

RAID 1 provides data redundancy and fault tolerance by duplicating data from one drive to another. If one drive fails, the RAID controller or driver rebuilds the data from the second drive to ensure uninterrupted operation. A RAID 1 array requires at least two storage disks (or pairs).

RAID 1 is ideal for storing critical personal and business data, such as. B. Accounting Systems. The only disadvantage of RAID 1 is that the total storage capacity is reduced by half. So if you have two 1TB storage drives, your PC will recognize them as one 1TB drive.

All Thunderbolt 3 RAID arrays with at least two drive bays support RAID 1.

RAID 5 corrects the weaknesses of RAID 0 by introducing disk striping with parity. At least three drives are required for this configuration. Unlike RAID 0, RAID 5 can survive the failure of a single disk. With parity distribution, data is stripped across multiple disks.

If you have three disks, two disks store the striped data and the third disk stores the parity checksum. Each write operation writes the parity data to another disk. When a disk fails, the RAID controller uses a parity check to restore the data block from the failed disk. RAID 5 can handle up to 16 storage disks.

TerraMaster D8, OWC ThunderBay 4, G-Technology G-Speed Shuttle, Promise Pegasus3 R6 and OWC ThunderBay 8 support RAID 5.

Compared to RAID 0, RAID 5 offers superior performance with an added layer of security. RAID 0 is of course slower than RAID 0, but it is a better configuration if you need both performance and fault tolerance with a limited number of disks.

RAID 6 is similar to RAID 5, but the parity checksum is stored on two disks simultaneously. It has better fault tolerance because it can tolerate two disk failures, but it requires at least four disks. However, it takes a lot of time to restore data in case of a failure.

Another common RAID level is RAID 10, which is a combination of RAID 1 (redundancy) and RAID 0 (disk shutdown). This configuration provides superior I/O performance with redundancy. Restoring data from a failed drive is faster because the RAID controller has to copy all the data from the mirrored drive to the new drive. However, this can be expensive for large storage streams, since half of the storage is used for mirroring. Thunderbolt 3 RAID storage enclosures with four or more drives support RAID 6 and RAID 10.

RAID 0 thus offers the best performance without fault tolerance. RAID 1 offers data redundancy, but you can only use half of the total storage capacity. RAID 5 offers decent performance during breakup and can survive the failure of a single disk. RAID 6 can survive the failure of two disks, but it takes much longer to recover the data. RAID 10 offers excellent performance and redundancy, but halves the total capacity of your storage system.

Form factor– Number of drive slots

The number of disk slots determines the RAID level you can implement in your enclosure. Entry-level 2-bay RAID enclosures such as the G-Technology G-RAID and the LaCie 2big Dock support both RAID 0 and RAID 1. You can choose power only or redundancy, but not both.

Next up is a 4-bay Thunderbolt 3 RAID drive that supports four drives. These enclosures can support more capacity than two-tier RAID arrays and also allow multiple RAID arrays to be set up. With four hard disks it is possible to configure RAID 0, 1, 5, 6 and 10.

The best 4-bay Thunderbolt 3 RAID arrays on the market are OWC ThunderBay 8 (software RAID) and G-Technology G-Speed Shuttle (hardware RAID).

Other RAID arrays may have six storage units, for example. B. the Promise Pegasus3 R6. It supports all standard RAID arrays and offers more storage space, which is beneficial for professionals and small businesses.

For businesses and professionals with power-hungry and demanding workflows, investing in an 8-bay RAID enclosure is the best solution. These enclosures offer a large storage capacity and allow the creation of local data centers for businesses and individuals. They support most RAID arrays and offer both performance and fault tolerance.

The TerraMaster D8 is the best 8-bay Thunderbolt 3 RAID drive you can buy on the market. If you are on a budget, the OWC ThunderBay 8 with software RAID is a great alternative.

Number of zippers 3 connections

Only one Thunderbolt 3 port is needed to connect a Thunderbolt 3 bay to a laptop or desktop computer. But with two or more Thunderbolt 3 ports, you can free up bandwidth for daisy-chaining, so you can connect up to six more devices to your computer with a single cable. The second Thunderbolt 3 port can be used to daisy-chain two 4K monitors or other Thunderbolt 3 devices.

Fortunately, with the exception of the Glyph Atom RAID SSDs, all Thunderbolt 3 RAID arrays discussed in this guide have two Thunderbolt 3 ports. G-Technology G-RAID and LaCie 2big Dock feature an additional USB-C port for added flexibility.

Other ports and connections

A RAID-enabled Thunderbolt 3 storage enclosure with additional ports beyond Thunderbolt 3 is useful if you’re using the latest laptops with limited ports. It’s getting harder to find outdated video outputs and USB-A ports on the latest lightweight laptops, like the 13-inch MacBook Pro and Dell XPS 13.

Most Thunderbolt 3 RAID storage enclosures have two Thunderbolt 3 ports and HDMI or DisplayPort outputs for connecting an external display. Although Thunderbolt 3 is getting a lot of hype, many monitors on the market still use HDMI and DisplayPort. It’s nice to have one of the old video ports.

The LaCie 2big Dock features the best combination of ports with two Thunderbolt 3 ports, USB-C, USB 3.0 Type-A for older devices, and two SD card slots. This is the best Thunderbolt 3 RAID enclosure if you have a lot of old USB devices and new USB-C devices.


Most RAID boxes are not easy to repair. We recommend buying a Thunderbolt 3 RAID array with an outstanding warranty of at least three years. G-Technology G-RAID and LaCie 2big Dock come with an excellent five-year warranty. Some brands, such as B. OWC, offer different warranty periods for the enclosure and the included disks. This is something that you should pay attention to before investing your money.
