The summary graphic below from the Router Charts shows write and read storage performance for USB 3.0 connection and NTFS format for the top 10 products tested with the latest Version 9 process. The RT2600ac was at the bottom of the group at 40 MB/s write, but in the #5 spot for read with 90 MB/s. USB 3.0 / FAT32 performance measured 43 MB/s write and 105 MB/s read.
Note you need reach the Router's share using \\192.168.1.1; you can't browse to it using Windows' network browser. Guest (no login) access didn't work, so the admin account was used to test storage performance. The media server wasn't running during the performance test.
Storage Performance Comparison - USB 3.0 / NTFS
Routing throughput was measured using the V4 router process with the router loaded with SRM 1.1.3-6447 Update 2 firmware. Table 2 summarizes the results: this Excel test summary contains all functional and performance test results. The NETGEAR R7800 is included for comparison because of its very similar hardware design.
Both routers have essentially identical TCP/IP routing performance, maxing out our measurement ability. The Synology scored slightly higher on the functional test but had one serious test failure, i.e. one of the firewall tests found port 80 open to the WAN side.
|Test Description||Synology RT2600ac||NETGEAR R7800|

The Synology RT2600ac is Wi-Fi certified. It was tested with the V9 wireless test process with SRM 1.1.3-6447 Update 2 version firmware loaded. Channel 6 and 20 MHz B/W mode was set for 2.4 GHz and Channel 40 and 80 MHz B/W mode was set for 5 GHz. The router was positioned in the test chamber as shown in the photo below. I'll be comparing performance to three other 4x4 routers tested with the V9 process: NETGEAR R7800; TP-Link Archer C3150 and ASUS RT-AC88U.
Synology RT2600ac in test chamber
Comparing average 2.4 GHz throughput for the selected routers tested shows the RT2600ac essentially tied with the TP-Link with 78 Mbps average throughput on downlink, but 71 Mbps on uplink; a 10 Mbps average throughput lead.
2.4 GHz average throughput comparison
Comparing average 5 GHz throughput shows the RT2600ac not faring as well, coming in last on downlink with 241 Mbps average throughput and next to last with 203 Mbps on uplink.
5 GHz average throughput comparison
Moving on to throughput vs. attenuation plots, for 2.4 GHz downlink, the RT2600 does very well, tracking the ASUS and TP-Link for most of the run. It also ends the run with higher throughput than the three other products.
2.4 GHz Downlink Throughput vs. Attenuation
For 2.4 GHz uplink, the RT2600ac maintains the highest throughput throughout its entire run. The only minor negative is that it disconnected before running the 63 dB test.
2.4 GHz Uplink Throughput vs. Attenuation
5 GHz downlink is a tougher call. The Synology starts out slightly below the NETGEAR, but above the ASUS and TP-Link. But the RT2600ac's throughput starts trending downward almost immediately and dropping below the other three routers from 12 dB onward. It recovers only slightly at the last two tests in the run. I can't explain the NETGEAR R7800's odd curve shape, but it's definitely there and definitely repeatable.
5 GHz Downlink Throughput vs. Attenuation
5 GHz uplink shows all products in a fairly narrow range. For all intents and purposes, all three are equal for this benchmark.
5 GHz Uplink Throughput vs. Attenuation
The takeaway for me is that the RT2600ac's performance is more in line with other 4x4 routers than the RT1900ac was for other 3x3 products. Unfortunately, its performance is weakest where you would want it to be strongest—5 GHz downlink.
