How to Choose the Best Thunderbolt RAID?

thunderbolt 2 raid enclosure


- RAID 0. In terms of operational speed, this type is the absolute best. Due to the absence of RAID overhead, the discs are simply merged into one item of storage with ultimate write-and-read speed for your computer’s convenience.

- RAID 1/10. This is a somewhat tricky option because if you go for RAID 1, your speed will just remain regular. With a RAID 10 configuration, you get a substantial boost because more discs are handling data simultaneously and shortening operation time. The trick won’t work when you’re processing a sequence of miniature tasks.

- RAID 5/50. This configuration is appropriate for when you need to read the data in abundant quantity. Writing is a lengthy procedure and even incorporating Thunderbolt RAID connection will not accelerate it. Parity makes things slow, as well as protected, and should you have to go through a rebuild, there will be an additional load on the system for recreating the lost information units.

- RAID 6/60. Being more secure than the previous option, this system takes an even longer time creating data entries with dual parity. Reading is still swift here. In the case of disc replacement, the restoration process will take a great toll.


- RAID 0. In terms of utilization, this is the best option. You have absolute access to all the storage you install due to the total absence of mirroring.

- RAID 1/10. This setup is the one with the worst capacity allowance. Exactly half will be inaccessible due to the need to copy all the information entirely. This is only a decent option when you care for processing speed as well as safety because RAID 1/10 can perform read/write tasks faster than the following alternatives.

- RAID 5/50. With parity instead of copying, you only lose 33% of the storage (with a 3-disc configuration) to the safety procedures. By mindfully creating your volumes, you can achieve optimum performance, security and capacity with this type.

- RAID 6/60. This alternative has a heavy 50% toll on capacity as well, and the double-parity processes also decrease the speed of operation greatly. However, this type is growing in popularity as the safest, the most damage-resistant option.


- RAID 0. If you’re only interested in space and operating speed, this type is the one with the best price per TB of space enabled for use. For those who have no need for safety options, this will be a great deal.

- RAID 1/10. For those who need affordable and secure storage with great performance, a Thunderbolt RAID 1/10 could be an option. This system takes a heavy tax, depriving you of exactly half the available space to provide safety. However, operating speeds remain high and from a certain perspective, the price is reasonable.

- RAID 5/50. For users that prioritize capacity and safety, this is already a sort of standard. Unlike the previous option, it only takes a little of your space for parity but creates the same level of security. However, the algorithm employed here is time-consuming so the use of storage becomes considerably slower. In that respect, the price for write workloads is unjustifiably high.

- RAID 6/60. This will be the least cost-efficient alternative appropriate only for utmost data security at the expense of everything else. The protocol takes half of the available space to create parity copies and since they are two, the write speed is even lower than that of the previous option.


thunderbolt raid 5

- RAID 0. This option will be the most available but the catch is that an important function is missing here. Technically, you just get a collection of discs united for the convenience of computer collaboration. You get the entire capacity of the discs and agile operation, but there is no protection of your data. If you damage any disc, the entire system will collapse.

- RAID 1/10. This is a device with decent availability where in each array, the data is doubled. Technically, damage can be caused to one disc in every array with your data remaining readable and the whole system functioning.

- RAID 5/50. This is a somewhat more favored option that companies frequently install. If you have RAID 5, a disc can be lost and the functionality preserved. Losing another one will be fatal, however. Instead, with the RAID 50, every subarray can lose a disc, and the functionality of the entire structure will be preserved after that.

- RAID 6/60. This is the system with the highest level of availability and protection. Unlike the previous build, two discs of an array can be lost with no consequences to your data.


  • • What is RAID?

It stands for Redundant Array of Independent Disks, although an earlier mentioning might have Inexpensive as the third word. The whole system, which is frequently referred to simply as "array", consists of several hard drives united into one flexible and capacious system with numerous benefits. 

  • • Why Thunderbolt for RAID systems?

With the best Thunderbolt RAID storage system, you can obtain speeds as high as 40Gbps. A well-optimized writing task can be performed at 5 GB per second through this cable. Take a USB 3.1 of the later generation, and you will get underwhelming 1.25 GB per second for writing. This huge difference is due to a tiny piece of electronics that makes the Thunderbolt plugs active.

  • • Where to buy an inexpensive Thunderbolt RAID?

Amazon is a great shopping spot for these devices.

  • • Which high-performance Thunderbolt RAID to buy?

The G-Technology G-RIDE is among the absolute leaders of the past year.
