A promising NAS device with plenty of features and connectors, but large-file reading lets it down.
A sustor is a relatively new player in the UK market, but from the look of what it has to offer this month, the company has considerable potential.
The AS5002T is a two-drive NAS device with a sober grey-and-black chassis. The front bays are hot-swappable, although you can’t lock them shut to prevent tampering. You also have to screw the hard disks in place, instead of using a faster tool-free design.
When it comes to connectivity, the AS5002T is hard to beat. There’s a USB 3 port on the front and another two on the rear, plus a pair of USB 2 connectors and a pair of Gigabit Ethernet ports. There are also two eSATA ports, plus HDMI and optical S/PDIF. The affords extra expansion for home-office users, alongside facilities geared towards a home media server.
As with many NAS devices these days, the main web interface uses a row of icons, and the submenus aren’t so full of options that they become confusing. There’s an app infrastructure available, with a sizeable array of software you can download and install. This includes Avast Anti-Virus, which is welcome as no antivirus is installed by default. There are useful corporate functions such as the ability to configure the NAS device as an iSCSI target and to balance the load on the Gigabit Ethernet ports.
With its dual-core 2.4GHz Intel Celeron J1800 and 1GB of DDR3L memory, the AS5002T has performance potential. Unfortunately, this was never fully realised in our testing. It performed well when writing a single large file at 88MB/sec, but reading was by far the slowest in this month’s selection, at only 56MB/sec. The AS5002T fared better with our large collection of smaller files, recording a better-than-average time.
The Asustor AS5002T is a capable NAS device, and at less than $430, it’s reasonably priced for small businesses. Its large-file reading speed lets it down, costing it an award this month by a very narrow margin.
