With the release of both the 802.11AC and the 802.11AX, we can sure say that consumer routers are ready and well-equipped for a future with 2.5Gbe. At this point, almost every vendor today that urges for the 801.11AX or the Wi-Fi 6 router can provide a quick fix with at least a 2.5Gbe LAN connection.

And since ASUSTOR made the shift to 2.5Gbe via a mainstream platform, the company produced an entirely brand new segment focused on gamers, creators and enthusiasts that would take advantage of the ability to save live streams to their NAS devices together with standard media. These typical files include music, videos, and photos.

Today, we’re going to focus on the Nimbustor 4 AS5304T NAS from ASUSTOR. It’s a model that comes with 4-bays and is technically the second-gen of ASUSTOR-enthusiast products. But is it as good as they claim it to be, and are the functions as efficient as well?

In this review, we’ll check out more about the product, its features, specifications, and how well it performs to see if it’s something worth purchasing. But first, what’s inside the box?

Asustor Nimbustor 4 AS5304T NAS Review – What’s in the Box?

When we first got the Nimbustor 4 AS5304T NAS, it came in a sturdy-looking cardboard box and the typical theme that the company goes for. Just like their other retail packaging, ASUSTOR aimed for the usual graphic packaging where the essential details are displayed. These include information on what the unit can do, its hardware & software specifications, and everything else that creates an engaging, as well as an appealing retail design.

Inside, the Nimbustor 4 AS5304T NAS is nicely-packed, keeping it from acquiring any damages while in transit. Cushioned between two huge Styrofoam blocks then covered in a durable plastic bag, you’re sure to have a well-protected NAS. There’s a separate carton in the box that keeps the power brick and other items included.

Aside from the unit, other items inside the box are the 90-Watt external power supply (100 Volts to 140 VAC), a mains power cable, two RJ-45 LAN cables (Cat 5e), a pack of flat head screws for the 2.5-inch HDD, an instructional manual, and quick start guide.

The Product

Asustor Nimbustor 4 AS5304T NAS Review

Based on what we’ve seen, the Nimbustor 4 AS5304T NAS is one of the best-looking 4-Bay NAS in the market. As a current trend, this unit doesn’t sport a fixed or hinged front panel, so it’s easily removable. It only means that when the NAS isn’t working on its daily tasks and not used physically, the Nimbustor 4 AS5304T NAS will be a contained unit that blends nicely and neatly in most office environments.

What’s more, the removable panel is slightly elevated, allowing more air to enter on all sides. This design is a way to guarantee non-interrupted active airflow from the fan.

Like the contemporary edged design of its front panel, the Nimbustor 4 AS5304T NAS’ sides feature an angular edge to the surface. For its chassis, it only comes in a black shade and comes with a plastic outer body that surrounds an inner metal frame. Also, when you look at the screw layout, it is a fixed frame that doesn’t sport a design that opens for maintenance or upgrades. So, if you’re looking for ways to update your memory higher than its default, you will find RAM slots within the unit by removing its internal bays, then accessing the two SO-DIMM memory module areas.

The Nimbustor 4 AS5304T NAS’ base comes with rubber feet plus an enormous ventilation slot that spans the bottom of the unit. It is to better assist passive airflow via the Hard Drive or SSD installed within the Nimbustor 4 AS5304T NAS.

When removing the front panel of the NAS, you will find its SSD or HDD media bays. The four bays of the Nimbustor 4 AS5304T NAS support the latest SATA-based Solid State Drives (SSDs) and Hard Drives.

Also, you can install a mix of SSDs & Hard Drives in individual bays, which can be utilized to produce separate RAID-enabled storage pools for regular or quick access to data volumes. Generally, it’s becoming more frequent for businesses and small offices to use 4-Bays with SSD and HDDs installed for more significant amounts of storage space that’s backed by a part of SSD caching. It then results in a boosted internal performance when working from slower mechanical hard drives.

Since its trays sport a plastic body, we didn’t need a screwdriver for it, and instead, utilized its click-and-lock brackets. We attempted to install a new drive to see if there were any problems with their larger enterprise. To our surprise, everything went smoothly. We didn’t encounter any issues in the process, which was great.

If not, you can always utilize one or more SSDs for raw caching or storage; but remember, you’ll need to use a screwdriver and the included screws for this. Also, to take advantage of the read & write caching, you’re required to have two drives installed, though a single SSD will let you use and enable the read-only cache.

All in all, this 4-Bay provides you an adequate amount of storage potential, and the Nimbustor 4 AS5304T NAS can efficiently do this with just minimal space used.

To see the media bays of the Nimbustor 4 AS5304T NAS, it’s necessary to remove the front panel of the NAS device. Other than the bays, you will also find the USB copy button and the LED indicators as well. Although these are pretty standard in all 2019 NAS drives, it’s worth noting that a lot of famous NAS brands have simplified or removed most of these, which has somehow displeased several users.

The front displays the LED lights that indicate the following: power/standby, system activity (read & write actions in progress), network access or activity (one for every port), as well as drive activity (one for each drive regardless of the available RAID). The quickest and most straightforward way to backup files on a NAS device via portable offsite-manner is by linking a USB 3.0 device then utilizing the ASUSTOR backup tools to establish a backup.

A single-touch USB copy button only means that you’re not even required to connect with the NAS software after the very first time, as well as after it’s configured to backup important files. Just link the USB device every time before pressing the button to action a backup immediately.
