TerraMaster D2-310 2-Bay DAS Performance

We will run our benchmarks using 2x HGST 10TB Hard Drives and 2x Crucial M500 SSD’s using RAID 0 and RAID 1 configurations. Generally, we suggest RAID 1 for redundancy. We are going to run through a number of utilities to see the performance. We are going to first look at the 10TB hard drive performance, then we are going to look at SSD performance.

CrystalDiskMark Performance

Here we see the results of our RAID 0 and RAID 1 tests using the HGST 10TB hard drives.

One can see the impact of using the simple RAID versus a more robust, and costly, solution. Read speeds are good but write speeds are less than half of what one can get on 1GbE networking using one of TerraMaster’s NAS units and hard drives. There is a massive delta between hard drive and SSD performance.

ATTO Disk Benchmark HPerformance

ATTO shows almost double performance in RAID 0 at 450mb/s vs 250mb/s in RAID 1, it does drop off at large test loads.

That fall-off is quite notable. It likely indicates an architectural limitation of the embedded RAID processor.

SSDs, on the other hand, are able to perform well and not see the same drop off in performance.

Parkdale Performance

Here are the Parkdale hard drive RAID 0 results:

Here are the Parkdale SSD RAID 0 results:

Here are the Parkdale hard drive RAID 1 results:

TerraMaster D2 310 RAID 1 2x HGST 10TB Parkdale
TerraMaster D2 310 RAID 1 2x HGST 10TB Parkdale

Here are the Parkdale SSD RAID 1 results:

TerraMaster D2 310 RAID 1 2x Crucial M500 Parkdale
TerraMaster D2 310 RAID 1 2x Crucial M500 Parkdale

Overall, these are good results and about what we would expect from the DAS. When we see similar read or write speeds using SSDs and HDDs, it is usually a limitation of the interface or the DAS.

PCMark 8 Benchmark

Here are the PCMark 8 hard drive RAID 0 results:

TerraMaster D2 310 RAID 0 2x HGST 10TB PCMark 8
TerraMaster D2 310 RAID 0 2x HGST 10TB PCMark 8

Here are the PCMark 8 SSD RAID 0 results:

TerraMaster D2 310 RAID 0 2x Crucial M500 PCMark 8
TerraMaster D2 310 RAID 0 2x Crucial M500 PCMark 8

Here are the PCMark 8 hard drive RAID 1 results:

TerraMaster D2 310 RAID 1 2x HGST 10TB PCMark 8
TerraMaster D2 310 RAID 1 2x HGST 10TB PCMark 8

Here are the PCMark 8 SSD RAID 1 results:

TerraMaster D2 310 RAID 1 2x Crucial M500 PCMark 8
TerraMaster D2 310 RAID 1 2x Crucial M500 PCMark 8

There is fairly clearly a limitation here in terms of random I/O performance, largely due to using hard drives rather than SSDs. This is one of those use cases that SSD vendors will trumpet as a reason to use SSDs over HDDs.

Blackmagic Disk Speed Test

We have also started using BlackMagic Design Disk Speed Test to show those doing video how well storage performs. We show RAID 0 on the left and RAID 1 on the right.

Using hard drives in RAID 0, ProRes 422 HQ at 2160p30 is possible. Using RAID 1 will limit one to 50fps editing. That is a practical limitation of the design.

Here, one can see that ProRes 422 HQ at 2160p60 is possible which is a major upgrade over hard drives in the unit.

Next, we are going to look at key specifications as well as our conclusion.

  1. Nice review, but i have questions.

    – Is it possible to read S.M.A.R.T. data from disks in all modes? Raid 0, raid 1, jbod and single? For example using gsmarcontr (windows gui of smartmontools)?

    – And which chipset is used for usb connection?
    Because i have some bad experiences with asmedia chipset regarding smart-data readings

  2. What is a real life transfer speed of USB 3.1 gen1? I guess it is slower than 2x SSDs in RAID so gen2 port would have been a better option here.

  3. Any info on what RAID controller it uses?
    Is there a chance we will see a follow-up with comparisons against Raiodon devices (OEM for some Icy-bow devices, and available under their own brand too)?
