QNAP TS-464 Performance vs the QNAP TS-453D

Review Configuration

For this review, the TS-464 was configured with four WD Gold 22TB HDDs, compared to the TS-453D which was configured with four Red 14TB HDDs.

Enterprise Synthetic Workload Analysis

Our enterprise shared storage and hard drive benchmark process preconditions each drive into steady-state with the same workload the device will be tested with under a heavy load of 16 threads with an outstanding queue of 16 per thread, and then tested in set intervals in multiple thread/queue depth profiles to show performance under light and heavy usage. Since NAS solutions reach their rated performance level very quickly, we only graph out the main sections of each test.

Preconditioning and Primary Steady-State Tests:

  • Throughput (Read+Write IOPS Aggregate)
  • Average Latency (Read+Write Latency Averaged Together)
  • Max Latency (Peak Read or Write Latency)
  • Latency Standard Deviation (Read+Write Standard Deviation Averaged Together)

Our Enterprise Synthetic Workload Analysis includes four profiles based on real-world tasks. These profiles have been developed to make it easier to compare to our past benchmarks as well as widely-published values such as max 4k read and write speed and 8k 70/30, which is commonly used for enterprise drives.

4k Performance Results

First up are the enterprise workloads, where we measured a long sample of random 4K performance with 100% write and 100% read activity. The TS-464 NAS configuration outperformed the TS-453D in SMB read operations, but otherwise, they were very similar. For IOPS, the NAS gave SMB scores of 2,437 IOPS read and 678 IOPS write, compared to the TS-453D configuration which had 292 read IOPS and 669 write IOPS. For iSCSI, the TS-464 achieved 2,491 IOPS read and 715 IOPS write, compared to 2,553 read IOPS and 444 write IOPS for the TS-453D.


In our 4k Average Latency tests, the TS-464 NAS showed 105.02ms read and 378.85ms write in SMB, and iSCSI reported 102.72ms read and 357.55ms write. Comparatively, the TS-453D had 874.06ms read and 382.29ms write for SMB, and 100.26ms read and 575.87ms write for iSCSI.


Next, in our 4k Max Latency tests, the TS-464 NAS reported 1129.2ms read and 4004.2ms write for SMB, and 105.69ms read with 15127ms write for iSCSI. The TS-453D reported 3181.8ms read and 4024ms write for SMB, and 6112.7ms read and 10535ms write for iSCSI.


In our last 4K test (standard deviation), we saw the QNAP TS-464 NAS with 76.69ms read and 562.122ms write for SMB, and 84.44ms read and 905.26ms write for iSCSI performance. The TS-453D NAS scored 734.97ms read and 458.11ms write for SMB, and scored 115.60ms read and 1148.64ms write for iSCSI.


8k Performance Results

Our next benchmark measures 100% 8K sequential throughput with a 16T16Q load in 100% read and 100% write operations. Once again, the new TS-464 NAS configuration with the Gold 22TB drives outperforms the TS-453D configuration on the SMB operations, reaching 54,894 IOPS read and 37,598 write, vs 29,180 read and 22,775 write for the TS-453D. On iSCSI it’s a bit mixed where the read operations are pretty even at 7,129 IOPS and 71,666 IOPS respectively, but the TS-464 NAS wins on writes with 57,947 IOPS vs the TS-453D with 37,598 IOPS.


Compared to the fixed 16 thread, 16 queue max workload we performed in the 100% 4K write test, our mixed workload profiles scale the performance across a wide range of thread/queue combinations. In these tests, we span workload intensity from 2 thread/2 queues up to 16 thread/16 queues. In SMB the QNAP TS-464 configuration starts out over 3x as fast as the TS-464 580 vs 178 IOPS), and ends up 7.5x faster on 16T16Q tests with 1320 IOPS vs 174 for the TS-453D. For the iSCSI tests, the TS-464 NAS starts 71% faster on the 2T2Q test, giving 523 IOPS vs 372 for the TS-453D. From there on it’s a bit of a mixed bag on the overall throughput, with differences being mostly marginal.


Looking at average latency with 8k reads/writes at 70%/30%, the TS-464 NAS is considerably faster than the TS-453D on SMB operations, never exceeding 189ms vs the TS-453D hitting 1462.55ms. In fact, the TS-464 average latency for SMB and iSCSI are virtually equal and match up with the results for the TS-453D iSCSI operational latency.



For maximum latency in our HDD configuration, in the SMB tests, the TS-464 ranged from 1035.81ms to 3155.6ms, compared to 387ms to 3448.21ms for the TS-453D. In iSCSI tests, the max latency for the TS-464 NAS ranged from 267ms to 8304ms, while the TS-453D ranged from 277.17ms to 6234.55ms max latency.


Moving on to the 8K 70/30 standard deviation results, the TS-464 configuration, once again, greatly outperformed the TS-453D configuration on SMB tests, with the TS-464 ranging from 13.4ms to 261.38ms, compared to the TS-453D which recorded a range of 35.24ms to 306.09ms in the SMB tests. In the iSCSI tests, the TS-464 configuration came out mostly ahead, recording latency numbers mostly below the TS-453D configuration, with the TS-464 ranging from 8.04ms to 357.39ms vs. the TS-453D which ranged from 19.25ms to 280.88ms.


The last synthetic benchmark is our 128K tests, which is a large-block sequential test that shows the highest sequential transfer speed for a device. In this case of SMB tests, the TS-464 with Gold 22TB drives achieved 6.8% lower throughput than the TS-453D with Red 14TB drives on reads, however, it achieved about 3.1% more throughput on writes. In the iSCSI tests, they are pretty even on read throughput, but the write throughput has the TS-464 configuration 9.3% faster than the TS-453D configuration.



With our two test configurations, the TS-464 meets or beats the older model TS-453D, which shouldn’t be too surprising. While in some cases these performance differences may not seem too great, considering the additional capabilities of the TS-464, much greater performance can be achieved.

While it’s great that the CPU processor in the newer TS-464 rates over 35% higher in CPU Passmark scoring, it also enables some of the additional capabilities that the TS-464 has over the TS-453D model, notably support for more memory, M.2 2280 NVMe Gen 3×1, PCIe Gen 3×2, and USB 3.2 Gen 2 (10Gb).

The TS-464 NAS can be expanded to 16GB of memory, which is twice the max memory available in the older model, and when coupled with the two onboard M.2 NVMe slots, the TS-464 can be configured with SSDs storage upgrades to achieve faster performance without needing to add an upgrade card.  In addition, the newer PCIe Gen 3 x2 slot enables the addition of expansion cards that can achieve twice the performance of the TS-453D model.

The result of all of these differences is that the newer QNAP TS-464 NAS can enable much larger workload growth while achieving even better performance. Combining all of this with the enterprise-class capabilities for storage protection and tiering, and at the $549 price point for the base model (without disks), the TS-464 NAS is a great value for SMBs and home users looking to add a scalable NAS to their network.
