Similar to Synology Hybrid RAID (SHR), TRAID (TerraMaster RAID) provides automatic combination of disk space, hard disk failure redundancy protection, and automatic capacity expansion - essential functions for storage space management.

Powerful Performance: Equipped with an Intel Celeron N4505 dual-core processor and two 2.5G Ethernet ports that deliver read and write speeds of up to 283 MB/s. Supports dual-channel memory of up to 32 GB, 4 GB DDR4 memory installed on base configuration. New Operating System: The F2-223 and F4-223 runs in the new operating system TOS 5 which offers more than 50 new functions and 600 improvements compared with the previous generation. The new features meet more business requirements, as well as significantly improving response speed, security, and ease of use.



TRAID (TerraMaster RAID)
A highlight feature of the new F2-223 and F4-223 devices is their support for TRAID, a flexible disk array management tool developed by TerraMaster. It offers several unique features that provide better storage space management. Learn more about the key features of TRAID above.

TRAID Key Features

• Flexible Disk Array Management: It has advanced features such as automatic combination of disk space, hard disk failure redundancy protection, and automatic capacity expansion.
• Higher Disk Space Utilization: TRAID's elastic strategy provides higher disk space utilization compared to traditional RAID modes.
• Easy Storage Space Expansion: With TRAID, storage space can be easily expanded by replacing the hard disk with a larger capacity and/or increasing the number of hard disks.
• Hard Disk Failure Redundancy Protection: TRAID can provide you with redundant protection against a hard disk failure, allowing a maximum of one hard disk to fail. Ensure your data is not lost in the event of a hard drive failure in the array.
• Migrate TRAID to TRAID+: You can migrate TRAID to TRAID+ by adding the number of hard drives. TRAID+ with redundant protection of 2 hard drives.

Pricing and Availability

• The 2-bay TerraMaster F2-223 is now available in the United States on Amazon for $299.99.
• The 4-bay TerraMaster F4-223 is also now available in the United States on Amazon for $439.99.

I would still rather use RAID5 or RAID6.

Does anybody know what file system TRAID is using and how it works?

Terramaster NAS’ New TRAID – What is it?

I don't get it. How they got 5TB! It must be 4TB in RAID 5.

How they calculate it?​

Similar tech:

• Synology SHR
  

  This didn't discuss what is required to recover data from a borked SHR system. When my Drobo (with their proprietary system) NAS wouldn't come back up after a sudden power outage, I found out how expensive it was to recover data from (or just repair) proprietary systems like theirs. The data was all there, but the organization was scrambled enough that it required specialist recovery. I'm not clear if Synology SHR has the same problem, and this video didn't address it. I've learned from this experience to use a UPS with a NAS and the associated on-site backup system. But the next time I set up a NAS, I'm considering RAID 5, 6 or 10 instead of a proprietary system because of the potential of free/open-source recovery options rather than expensive specialist recovery being the only possibility.

  TLDR its mdadm raids in one lvm2 volume.

  Say u have 4,6,8 and,8TB. With SHR, what total size u get?
  4 + 4 + 4 + 4 => 12
  0 + 2 + 2 + 2 => 4
  0 + 0 + 2 + 2 => 2
  So I have 12 + 4 + 2 = 18TB? Am I understanding SHR correctly?
  I actually have 3.6, 9.1, 10.9 and 10.9TB and now I see 18.2TB. Why not 23.6TB?

How they calculate it?

Their display of how they think RAID 5 works is deeply flawed and clearly displays their shocking ignorance. RAID 5 does not work that way.

In any RAID 5 array, whether it be the minimum 3 drive array or 25+, the controller stripes the data offset across all the drives with parity data. It does so at the cost of one drives worth of space.

In a 3 drive array, you lose 1 drive worth of space.
For example 3x4TB->RAID5=8TB of usable storage.

In a 25 drive array, you lose 1 drive worth of space.
For example, 25x4TB->RAID5=96TB of usable storage.

With RAID 6 array you two drives worth of space, with a 6 drive minimum.

6x4TB->RAID6=16TB

25x4TB->RAID6=92TB

As you can see, the more you scale the better value the array is.
