The AS-606T is equipped with a dual core Atom processor, which is quite enough to handle its needs because its custom-tailored Linux operating system has low processing power demands. It includes 1 GB of available memory that can, according to Asustor, be expanded to 3 GB. The NAS also supports up to six removable HDDs or SSDs (SSD support makes sense because their prices have dropped greatly) through the SATA III protocol to ensure the highest possible transfer speeds. Needless to say, all popular RAID levels are supported, which is something common to all NAS servers of this category. Finally, if you install 4 TB HDDs, its max capacity will reach 24 TB. This huge storage capacity will cover nearly anyone's needs, but you can go with the eight-bay AS-608T model if you need even more storage space.

The AS-606T is equipped with two Gigabit Ethernet ports, and you can, if you want, link them to achieve the maximum possible transfer speed. You will, in order for the link aggregation protocol to work, have to connect the NAS to an appropriate switch that supports the IEEE® 802.3ad Link Aggregation Control Protocol (LACP).

Regarding the I/O ports, the NAS is equipped with two USB 3.0 and four USB 2.0 ports, and two eSATA ports. As you can see, Asustor was quite generous with I/O ports, and you can easily hook many devices up to the AS-606T at the same time.

The dimensions of the NAS are neither small nor large since the AS-606T occupies about the same space as a regular HTPC, but its power consumption is much lower than most HTPCs. It, according to Asustor, only consumes 1.4W in idle and 40.3 W during operation; however, they forgot to inform us with what HDDs the AS-606T achieved a 40.3 W consumption during operation, and such information would have given us a nice point of comparison to our own power-consumption measurements.

The power supply that handles the needs of the NAS is an internal one since its casing by the famous Delta Electronics allows for one. It can deliver up to 240 W, so it will easily meet the requirements of the AS-606T.

The main cooling fan is 120 mm in diameter. Its large diameter makes it effective at even low rotational speeds, which helps in decreasing the output noise while maintaining a good level of airflow inside the chassis. The smaller 40 mm fan cools down the PSU of the NAS.

The warranty of the NAS is set at a short two years, like its competitors. It is worth mentioning that although the warranty period is short, a NAS usually works 24/7, so the operating hours over a two year period will greatly outnumber those of other IT products. Finally, the price of the AS-606T classifies it for the SMB category: the same category as the QNAP Pro models, which will make things pretty tough for the AS-606T. It does include far too many features and its hardware has the same specifications as the QNAP TS-669 Pro, so we have high expectations for it.
