We tested the Asustor AS-604T pedestal NAS exactly one year ago and found its performance above par compared to other products on the market in the same price range. Asustor took that same DNA and built two rackmount versions for the SMB / SME market. The first model, the AS-604RS, uses a single power supply, and the second model, the AS-604RD, uses redundant power supplies.
The AS-604RD is a cross-platform storage server. It works with everything, including Windows, Android OS, Apple, and even Linux. The ADM software is also quite powerful. Asustor's operating system has several built-in features, but the add-on packages deliver flexibility so that you can customize the server for multiple tasks that run at the same time like a virtual server but without the complication.
Hardware Specifications and Pricing
Modern NAS servers have moved beyond data storage through a wired network. In order to get the most out of a NAS, you need to look at the extra I/O hardware and the mountain of potential software features.
Powering all of the applications is an Intel dual-core Atom processor with HyperThreading. Asustor ships the AS-604RD with only 1GB of DRAM, but you can easily increase the capacity to 3GB by adding a single 2GB stick. We'll show that process later in this review.
The AS-604RD is different than the AS-604RS model in that it ships with a redundant power supply. The dual power supply does add around $100 to the cost. The single power supply unit sells for $997.99, and the redundant power supply model we're testing today sells for $1099.99 (all prices from Google Shopping).
Neither system ships with drive rails, so you'll need to purchase an Asustor Rail Kit, $145.99, to mount the system in a 4-post rack.
On the features side, the AS-604RD has four drive bays for either 3.5-inch or 2.5-inch disks. The NAS can run RAID 0, 1, 6, or 10 with an EXT4 file system. Two eSATA ports expand the total capacity of the system. Two USB 3.0 and four USB 2.0 ports increase the system's flexibility.
Two independent gigabit Ethernet ports can connect to separate networks or run one of six Link Aggregation modes. The NAS is a 1U design, so it easily fits in your existing rack.
