Asustor AS6204T Braswell NAS Reviewby Ganesh T S on November 5, 2015 8:00 AM EST
Asustor is one of the recent entrants in the NAS market. Over the last couple of years, they have tried to play in the same space as QNAP and Synology, targeting power users and SMBs. They have a wide variety of hardware platforms to choose from, ranging from ARM-based 2-bay systems to Xeon-based rackmounts. Asustor became the first COTS NAS (commercial off-the-shelf network-attached storage) vendor to introduce models based on Intel's 14nm Braswell SoCs back in September 2015. In this review, we take a look at the performance of the AS6204T, a 4-bay model.
Introduction and Testbed Setup
Asustor recently introduced ARM-based NAS models as well as an update to their Bay Trail models in order to serve both home consumers and SOHO / SMBs with better hardware platforms. Their Braswell lineup consists of four models, with each model name following the pattern AS6X0YT, where X (1 or 2) refers to the number of cores in the Braswell SoC in the model and Y (2 or 4) refers to the number of bays. The dual-core SoC used by Asustor is the Intel Celeron N3050, while the quad-core SoC is the Intel Celeron N3150. One of the more important updates in moving up from Bay Trail-based SoC such as the Celeron J1900 to the Braswell-based SoCs is the availability of AES-NI for accelerated encryption capabilities.
Asustor sampled us with the highest end model in the AS6xxx series, the AS6204T. The specifications of the Asustor AS6204T are provided in the table below. The corresponding specifications of some of the other contemporary NAS units are also included.

The various specifications of the NAS are backed up by the data gleaned via SSH access to the unit. The most interesting aspect here is the use of the Broadcom BCM57781 Ethernet controllers.
The industrial design of the Asustor units give us nothing to complain about. The LCD screen provides a quick way to look at and control the essential NAS configuration. The drive bays are solid and can take both 3.5" as well as 2.5" drives. The caddies also come with a basic locking mechanism to protect against accidental disk removal.
The setup process is quite straightforward. Upon connection to the network, the Asustor AS6204T receives a DHCP address even in a diskless state. The IP address can be determined either from the DHCP provider in the system or via the Asustor Control Center Windows / OS X utility. Starting off in a diskless state results in a prompt from the web UI to insert at least one disk in order to continue. The single disk can be configured in a JBOD volume and the login credentials can also be set up. The unit had no trouble in handling our standard RAID migration, expansion and rebuild operations using the 4TB WD Re drives.
In the rest of this piece, we will take a look at how the Asustor AS6204T takes advantage of the Braswell platform. We will be solely concentrating on objective metrics in this review. A discussion of the mobile apps, we UI and other subjective aspects will be covered in a future article. Benchmark numbers for both single and multi-client scenarios across a number of different client platforms as well as access protocols will be presented. We also have a separate section devoted to the performance of the NAS with encryption enabled. Prior to all that, we will take a look at our testbed setup and testing methodology.
Testbed Setup and Testing Methodology
The Asustor AS6204T can take up to 4 drives. Users can opt for either JBOD, RAID 0, RAID 1, RAID 5, RAID 6 or RAID 10 configurations. We expect typical usage to be with a RAID-5 volume. In order to keep things consistent across different NAS units, we benchmarked a RAID-5 volume with four Western Digital WD4000FYYZ RE drives were used as the test disks. Our testbed configuration is outlined below.
|AnandTech NAS Testbed Configuration|
|Motherboard||Asus Z9PE-D8 WS Dual LGA2011 SSI-EEB|
|CPU||2 x Intel Xeon E5-2630L|
|Coolers||2 x Dynatron R17|
|Memory||G.Skill RipjawsZ F3-12800CL10Q2-64GBZL (8x8GB) CAS 10-10-10-30|
|OS Drive||OCZ Technology Vertex 4 128GB|
|Secondary Drive||OCZ Technology Vertex 4 128GB|
|Tertiary Drive||OCZ Z-Drive R4 CM88 (1.6TB PCIe SSD)|
|Other Drives||12 x OCZ Technology Vertex 4 64GB (Offline in the Host OS)|
|Network Cards||6 x Intel ESA I-340 Quad-GbE Port Network Adapter|
|Chassis||SilverStoneTek Raven RV03|
|PSU||SilverStoneTek Strider Plus Gold Evolution 850W|
|OS||Windows Server 2008 R2|
|Network Switch||Netgear ProSafe GSM7352S-200|
The above testbed can run up to 25 Windows 7 or CentOS VMs simultaneously, each with a dedicated 1 Gbps network interface. This simulates a real-life workload of up to 25 clients for the NAS being evaluated. All the VMs connect to the network switch to which the NAS is also connected (with link aggregation, as applicable). The VMs generate the NAS traffic for performance evaluation. However, keeping in mind the nature of this unit, we restricted ourselves to a maximum of 10 simultaneous clients.
We thank the following companies for helping us out with our NAS testbed:
- Thanks to Intel for the Xeon E5-2630L CPUs and the ESA I-340 quad port network adapters
- Thanks to Asus for the Z9PE-D8 WS dual LGA 2011 workstation motherboard
- Thanks to Dynatron for the R17 coolers
- Thanks to G.Skill for the RipjawsZ 64GB DDR3 DRAM kit
- Thanks to OCZ Technology for the two 128GB Vertex 4 SSDs, twelve 64GB Vertex 4 SSDs and the OCZ Z-Drive R4 CM88
- Thanks to SilverStone for the Raven RV03 chassis and the 850W Strider Gold Evolution PSU
- Thanks to Netgear for the ProSafe GSM7352S-200 L3 48-port Gigabit Switch with 10 GbE capabilities.

extide - Thursday, November 5, 2015 - linkI think Purch could handle that expense. Anandtech isn't a little teensy website anymore, remember.
DanNeely - Thursday, November 5, 2015 - linkUnless your preferred solution is either the Toms Hardware (picked on only because I'm not sure what else Purch already owns) comment system reskinned to Anandtech colors or something completely off the shelf like Discuss; that might not be the best idea. I'm very leery of handing the job off to a corporate overlord who bought the site on the assumption of being able to pull extra money out of it and which has already triggered multiple complaints from readers about overly intrusive advertising.
milkod2001 - Thursday, November 5, 2015 - linkYou could possibly contact Purch: http://purch.com/#contact-general
(It own this website) and request it there. For such reputable company it is shame there is not edit option. It should not take more then 1 day to implemented it or just install DISQUS
Namisecond - Monday, December 7, 2015 - linkDon't underestimate the time it may take to transfer all the user accounts over. If the tools work fine and everything goes well in a single pass, it could take a day. If there are serious problems, might take several days to over a week.
extide - Thursday, November 5, 2015 - linkPerhaps it refers to the number of dual-core modules -- as that is how Intel builds those chips (in dual-core pairs)
dtgoodwin - Thursday, November 5, 2015 - linkPlease, please, could you review a moderately configured FreeNAS setup testing it the same way you do these? I know there are a tremendous amount of variables, and tuning available, but if you used the standard configuration of software, and chose a medium performance platform such as an i3, or core series Pentium or Celeron and tested it with 4 drives, it could be comparable.
I run a 7 drive RAIDZ2 with 3TB WD REDs. I am almost always able to saturate a single GB link using CIFS and robocopy or Windows file copy whether reading or writing. I'm running a less than optimal setup as I have 15 TB of usable space, but only 8GB of RAM. My system with a SuperMicro board with ICMP, 2 GB NICs, a Pentium G2030, and a used SuperMicro case cost me about $650 not including the drives.
Black Obsidian - Thursday, November 5, 2015 - linkI'm sure they could write such a feature, but the first 17 pages would be component selection, installation, lexicon (vdev, pool, stripe size, etc.), Shell Commands 101, and so forth.
And none of it would say anything new. Anyone running--or considering running--FreeNAS knows its performance capabilities, and anybody seriously considering a Synology/QNAP/Asustor product is going to be in a coma by the third page of such a feature.
DanNeely - Thursday, November 5, 2015 - linkThey wouldn't have to write those pages if they didn't want to. Just set general requirements and ask the hardware partners to donate a build as usual; or punt farther and get an entry level prebuilt freenas box from that company that's been selling them for years (albeit at a price that makes Synology/QNAP boxes look cheap). Default to RAIDZ5 to maintain parity with the rest of their 4 bay NAS reviews. Stick to setting it up via the installer/web config panel. The whole point of a product like freenas vs roll your own is that for typical nas use cases the user should never need to drop down to the shell or need to understand all of the magic behind the scenes. A single page on what ZFS does better than ETX4 on most linux based nases is really all that's needed.
Navvie - Friday, November 6, 2015 - linkHP Microserver G1620T. Upgrade RAM to 8GB. Hardware selection done.
FreeNAS/nas4free on USB stick. Default ZFS options that the web interface presents.
AnandTech seems to be making a big thing of NAS devices these days, ignoring the build your own device option is silly. Even if somebody is set on buying an off the shelf unit, it would be nice to see how much better it performs (or not) compared to a BYOD.
DCide - Thursday, November 5, 2015 - linkFor some reason Asustor always reminds me of the words stupid or stupor. Probably not ASUS' finest branding moment.
