Synology DS1522+ NAS + WD Red Pro 22TB – 10GbE Speed Tests – RAID 0 vs RAID 5

Synology DS1522+ NAS 10GbE RAID Testing with the WD Red Pro 22TB HDDs

Technology is moving FAST! Yet one of the most overlooked fast-moving areas of technology in the market is data storage! In the last decade we have seen data storage averages used by consumers and businesses hugely multiply in volume and frequency, with hardware providers rushing to meet this demand. Because storage scales have increased so rapidly and the limitations of ‘local’ data access have long since been abandoned in favour of remote sever and cloud services, the result is that brands like Synology (pretty much the no #1 Network Attached Storage provider in the world) and WD (arguably one of the biggest hard drive manufacturers in the world) have been producing high quality and high-performance solutions to support this. Today I want to talk about two of each respective brand’s business targetted 2022 releases, combine them and give you some idea of just want they can do! In this article, I will be taking the Synology DS1522+ Ryzen-powered NAS for a spin, alongside four of the new WD Red Pro 22TB NAS Hard Drives, in order to see the performance we can expect in a wide range of configurations. In today’s article I hope to identify the following:

  • The impact of different RAID configurations (with their different parity and redundancy calculations) on performance
  • Identifying the performance differences between small and large file volumes/frequency in overall throughput
  • Measuring the improvements in the performance of the WD Red Pro 22TB HDDs as multiple are in a RAID (performance increase as multiple drives Read/Write simultaneously)
  • Testing external throughput with both a 5GbE connection and 10GbE connection to identify the point of network saturation
  • Finally, to see if the DS1522+ more streamlined architecture is enough to support and perform at peak with the WD Red Pro 22TB Hard Disks

Hardware Used in today’s Tests

Synology DS1522+ & WD Red Pro 22TBs – The Test Setup and Hardware Used

These tests were conducted in a Windows 10 client machine environment over 3 days (factoring RAID rebuild times and cool downs). Although the DS1522+ NAS is a 5 bay NAS system, I was only able to secure four 22TB WD Red Pro HDDs, so that needs to be factored in. That said, the performance measurements of even 4 of these drives was still remarkably impressive for mechanical hard disks. The benchmark software used for these tests was Atto Disk Benchmark, as it provides a very wide range of test setups – as well as working much more smoothly with iSCSI targets/LUNs in windows and providing clearly information to display to the layman for this article. Lastly, I included a barrage of 5GbE network tests because, although current no Synology NAS hardware in the market features 5GbE network architecture, there is an increasing vogue for hardware client devices (PCs, Macs, etc) to have their network connections easily upgraded to 2.5G and 5G with USB adapters (for as little as £25) ensuring that a 10GbE connected NAS can be shared to a full extent with connected clients. Here is a breakdown of the specific test setup components:

  • Synology DS1522+ 5-Bay NAS, E10G22-T1-mini 10GbE Adapter, DSM 7.1

  • WD Red Pro 22TB NAS Hard Drives x4, RAID 0 or RAID 5 Configuration (depending on the test)

  • 20TB iSCSI LUN via the Default iSCSI Manager Target, connected to the Windows PC with the iSCSI initiator as a local appearing drive for Atto Disk Benchmark

  • Local PC Network Adapter USB-to-5GbE Adaper and a Thunderbolt-to-10GbE adapter (depending on the test requirements)
  • This slideshow requires JavaScript.

  • Windows 10 Pro PC, Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz 2.20 GHz, 32GB DDR4 2666Mhz Memory, Internal Samsung 970 Pro 1TB SSD

  • MTU / Jumbo Frames set to 9K on both the NAS and the Network Adapter, Direct Connection (LAN-to-LAN), no network switch

Before we go further though, we need something to measure against. Here is the default performance of a SINGLE WD Red Pro 22TB NAS Hard Drive, using the Synology DSM Storage Manager Benchmark Tool:

As you can see, even on it’s own, a single WD Red Pro 22TB HDD can largely saturate even a single external 2.5GbE connection (though, most Synology arrive with 1GbE or 10Gbe). So, at the very least, you are going to get 240-260MB/s with just the one drive. So, let’s get down to business! I performed a wide scope of tests, so let’s go through those results!

QNAP TS-464 NAS + WD Red 22TB RAID 6 Tests – Verdict & Conclusion

Overall, I was tremendously impressed with both the WD Red Pro 22TB drives AND the Synology DS1522+ NAS in these tests. My big takeaways from these tests were:

  • Despite the AMD Ryzen R1600 being a Dual Core Processor, it was easily able to handle even the heavy 16GB, RAID 5 performance tests with little system impact
  • The four 22TB Red Pro Hard Drives were particularly impressive, given they were able to able to fully saturate the 10GbE connection at numerous points
  • The drives and NAS in these tests tended to favour the Read performance, though Write performance was still great.

Of course, it is always worth remembering that these tests were based on synthetic scenarios that were generated by a benchmarking tool. So these do not necessarily translate directly into the results that you will get with my unregulated and general ad hoc use. However, there are still fantastic results for this NAS+HDD drive combo, especially at this more compact scale.

    1. One question: Why are the WD Red Pro 22TB HDDs all healthy? Did you edited the compatibility file on the Syno or anything else? Normaly only the 14TBs Red Plus are approved at Snologys compatibility matrix 🙂
      Thx in advance and Cheers
