The Bottom Line

ASUSTOR's AS6202T is a high-feature NAS appliance that carries excellent performance characteristics. On the downside, it's a bit more expensive than competing products.


Asustor AS6202T SMB NAS Review 10

At just about this time last year, many vendors were rolling out their products based on the new Bay Trail platform from Intel. With many of those products ushering in a new generation of performance that further pushed the uptick in power efficiency for NAS solutions, we now have the next evolution of the NAS platform as Braswell has emerged, and Bay Trail D takes a back seat.

If you were to take a look at the new 6000 series of appliances from Asustor, you wouldn't think anything has changed. This new run of devices uses the same shell that we found on the entire 5000 series that stretches back a number of years. Where you will find change is internal, with the heart of the appliance and for the AS6202T that starts with the Intel Celeron N3150. If you read marketing materials, Asustor would have surely let you know that they were first to market with the new Intel Braswell silicon, and while we weren't the first tech based website to post a review of this hardware, we have had it in the lab for a little while. In fact, we have had this particular appliance on the bench for the last month at least, testing several revisions of firmware.

Diving into the specifications of the AS6202T, we find the brain of the operation at the top of the list, the Intel Celeron N3150. This CPU operates at 1.6GHz and boosts to a touch over 2GHz. 4GB of DDR3 aids in the performance of this appliance while peaking inside the unit you will find a 512MB SATA DOM housing the OS firmware. The dual Gigabit Ethernet is powered by two Broadcom 57781 chips while the audio and SATA lanes come from a Realtek ALC887 and ASMedia 1061 IC, respectively. With this NAS solution being part of Asustor Power User to Business lineup, the price certainly matches up as this two bay AS6202T appliance carries an MSRP of $569.99 with a three-year warranty.

Starting new this year, we are now testing NAS solutions with solid state drives. This should show the overall performance of the NAS appliance itself rather than being bottlenecked by hard drives. As you can see above, our testing is powered by Crucial BX200 SSDs.

Starting off our single client testing, we have RAID 0 with the Asustor. It's worthy to note here that these tests are done with SSDs while prior NAS appliances were tested with hard drives.

Looking at our results, we find file copy coming in at 131 MB/s while playback and record comes in at 126 MB/s along with similar results in Video record. Single, two and four times video playback came in a 97, 116 and 114 MB/s, respectively.

Asustor AS6202T SMB NAS Review 41

Moving over to RAID 1, our results did not falter too much as we still have 117 MB per second on video record with 110 on file copy to the NAS. In our video playback testing, we found peak results to come in at four times playback at 103 MB per second while single and two times came in at 83 and 100 MB/s, respectively.

Benchmarks – Sequential Workloads

Our Sequential read/write workload is centered on 128K transfer sizes.

Asustor AS6202T SMB NAS Review 42

Sequential read results for the AS6202T came in at 118 MB/s from start to finish.

Asustor AS6202T SMB NAS Review 43

Sequential write started out at 64 MB/s then ramped up to a peak of 115 MB/s.

Asustor AS6202T SMB NAS Review 50

If we look at RAID 1, sequential results touched the same 118 MB/s read.

Asustor AS6202T SMB NAS Review 51

While write performance within RAID 1 did fall slightly, but the Asustor unit did bring in a peak of 91 MB/s.

Asustor AS6202T SMB NAS Review 44

For the SMB workloads, I have removed all the previously tested NAS appliances. This is because I didn't want appliances tested with hard drives mixed in with SMB workloads because there's too much of a difference in the results. As you can see here with the database workload on RAID 0, the Asustor unit was able to hit near 4600 IOP's.

Asustor AS6202T SMB NAS Review 45

Moving over to file server, we find the AS6202T steadily increase its performance through the queue depth scale. At QD1, we are just under 2000 IOPS while moving up we come to a peak of 5000 at QD128.

Asustor AS6202T SMB NAS Review 46

Looking the email server, we find similar performance with QD1 just under 2000 while moving up to a peak of 4900 IOPS at QD8.

Asustor AS6202T SMB NAS Review 47

Web Server picked up slightly as peak results came in at 5200 IOPS.

Asustor AS6202T SMB NAS Review 48

In our workstation workload, we found the Asustor to reach 5500 IOPS coming at QD8 through QD128.

Asustor AS6202T SMB NAS Review 52

Results for this start just south of 1500 and move up gradually to a peak of 3300 at QD8.

Asustor AS6202T SMB NAS Review 53

This NAS appliance got beat up pretty good with file server as results were barely able to reach over 1000.

Asustor AS6202T SMB NAS Review 54

Email server bounced back as QD1 started at 1300 and gradually moved up until it reached a peak of 2400 IOPS at QD4.

Asustor AS6202T SMB NAS Review 55

Moving on to Web server, we start with a low of 400 IOPs at QD1 and moving towards QD8 we peak at just over 700 IOPS.

Asustor AS6202T SMB NAS Review 56

Workstation again showed promise as the AS6202T started at a respectable 1400 IOPS reaching a peak of 2300 IOPS at QD16.

Final Thoughts

Asustor AS6202T SMB NAS Review 10

Over the years, Asustor has built itself a solid reputation coming from the new kid on the block just a few years ago to one of the big players in today's market. With each passing generation of NAS appliance, their ADM platform gets better, and the underlying hardware gets more efficient. With that said, build quality with Asustor has always stayed the same, at least with SMB appliances. The AS6202T enjoys the same quality I have become familiar with in past 5000 series appliances; the same steel structure and shell gives these units solid durability while the plastics on the front panel give it a soft appearance.

The performance of this unit was quite solid and if it's any indication it appears the Intel Braswell platform is a winner. In our single client test, I was able to maximize the throughput of our gigabit connection in both RAID 0 and RAID 1 while sequential numbers were able to reach upwards of 118 MB/s. On the flip side, our workload testing showed great promise with the Asustor unit as we were able to reach over 5000 IOPS on several occasion in both RAID 0 and 1.

ADM has been improved upon since our last foray with an Asustor appliance. You still get the basic requirements for transferring and storing your data with CIFS, AFP, and NFS support, while on the higher-end TFTP, iSCSI and Terminal give you high-level features for the power user. Adding to this are all the media and encryption features that are now baked in including AES-NI and 4K HDMI support via KODI along with hardware transcoding capabilities.

Overall, the Asustor AS6202T is a solid NAS appliance and quite possibly the quickest two-bay appliance we have tested which makes sense as this unit appears to share the same configuration with its four-bay counterpart. The level of features you get with this appliance is top notch and with this unit carrying an MSRP of $569.99 with a three-year warranty, it's quite competitive in the market as well.
