Version 3.00.03.n2810 (Thecus OS7) firmware was loaded onto the N2810 and performance tests were run using the Revision 5 NAS test process. All tests were run using our own Western Digital Red 2 TB (WD20EFRX) drives. The test volumes were created using EXT4.
The composite image below shows File Copy Write and File Copy Read performance for two drive NASes tested with the Revision 5 test process. For File Copy Write, the N2810 turned in 109.7 MB/s which was slightly lower than the chart-topping 110.5 MB/s. For File Copy Read performance, the N2810 was near the top of the charts at 108.6 MB/s
Note that quite a few NASes in both charts cluster between 109 and 110 MB/s. That's about the maximum throughput that you can achieve with single client Gigabit Ethernet testing. And, we have noted in other reviews, performance within 5% of each other is ranked the same. What's important here is the N2810 is in the top tier and within the 5% tolerance for both tests.
File Copy Write and File Copy Read performance for two drive NASes
For performance comparisons, I'm using the same products included in the Key Component summary table above. Both the Thecus N2810 and the ASUSTOR 6102T were tested with the EXT4 file system. The Synology DS216+ was tested with the default BTRFS file system.
The benchmark summaries below show the individual test results for each of the three selected products. For all three products, both the RAID 0 and RAID 1 File Copy Write and Read benchmarks were within a couple of percentage points of each other and near the maximum throughput of a single Gigabit Ethernet client. NASPT File copy to NAS and File Copy from NAS were similarly consistent for both RAID levels with the exception of File Copy from NAS for the Thecus N2810. It turned in a performance that was well below 100 MBps - 88.9 MBps for RAID 0 and 81.7 MBPS for RAID 1.
The N2810 lacks USB 2.0 ports as well as eSATA ports, so tests could only be run for USB 3.0 and network backup. For USB 3.0, the Synology DS216+ had the fastest backup performance for all file systems tested (FAT, NTFS, EXT3). The Thecus had the best network backup by a significant margin. It measured 108.9 MB/s compared to the AS6102T (59.5 MB/s) and the DS216+ (57.2 MB/s). The N2810 also outperformed the other two NASes for iSCSI Write and Read.
Benchmark summary comparison
The composite NAS ranker chart below was filtered for RAID1 and Revision 5 testing and sorted by rank. Priced at $288, the Thecus N2810 is the least expensive of the three NASes compared. But it also ranks #10 (lower) than either of the other two compared NASes.
RAID 1 NAS Rank - Sorted by rank
If you sort the NAS Ranker by price, however, something interesting pops out. There are three NASes that are priced lower than the N2810 and also have a better (lower) NAS ranking. As we have seen in other reviews of two-bay NASes, the #4 ranked Marvell-based Synology DS216 offers a lot of bang for the buck.
RAID 1 NAS Rank - Sorted by price
The chart below shows the individual and category scores for the same three NASes used in the benchmark summary above. The Thecus N2810 had only one category win - iSCSI - compared to the other two NASes. The N2810 did fairly well in the backup category, but the relatively slower NTFS USB 3.0 result dropped it behind the Synology DS216+. Mixed Read Write was also a good category where the N2810 placed just behind the #2 ranked DS216+. The N2810 ranked #11 for Read Benchmarks primarily because of the relatively low NASPT RAID 0 and RAID 1 File Copy read tests previously noted.
Ranker Performance Summary comparison
The Thecus N2810 is priced about the same as the QNAP and Synology Intel Braswell-based NASes we've reviewed, but ranks significantly lower in our performance rankings. That said, in real-world use with a single Gigabit Ethernet connection, you would have a difficult job seeing much difference in file copy performance.
OS 7 aside, Thecus still lags behind QNAP and Synology in features and user interface sophistication for "kitchen sink" NASes, i.e. products looking to offer as many features as possible. So it's unlikely to win any converts from those camps. But if you're a Thecus fan looking to move up to a more powerful RAID1 class NAS, the N2810 won't disappoint.
