Flashstor 2 Design and Build

The Asustor Flashstor Gen 2 impresses with its compact design, measuring just 48.3mm (H) x 308.26mm (W) x 193mm (D). Its compact size belies the immense capability housed within, including support for up to 12 M.2 NVMe drives. This layout makes it well-suited for professional environments where space efficiency and quiet operation are critical.

The choice of hardware components further solidifies its status as a high-performance NAS.

At the heart of the device is the AMD Ryzen Embedded V3C14 processor, a quad-core CPU clocked at 2.3GHz with a boost speed of up to 3.8GHz.

It supports 16GB of DDR5-4800 ECC memory, which is expandable up to 64GB, catering to users with intensive storage and processing requirements. ECC memory enhances data reliability, making this NAS suitable for mission-critical workflows.

The system’s chassis is thoughtfully designed for durability and accessibility. Internal components, such as the NVMe slots, are easily accessible for maintenance or upgrades. The 12-bay configuration maximizes storage potential, making it ideal for users managing large-scale projects or requiring extensive data redundancy.

Despite its compact size, the Flashstor Gen 2’s design includes practical enhancements for thermal efficiency, which we’ll discuss further in the performance section. Overall, the hardware selection and physical layout highlight Asustor’s focus on balancing power and practicality.

Performance and Heat Management on the Flashstor Gen 2

The Flashstor Gen 2 is engineered to deliver top-tier performance, leveraging its powerful hardware and advanced connectivity.

Testing showed the device consistently saturating single 10-Gigabit Ethernet connections during file transfers, with dual connections offering even greater throughput.

Its USB 4.0 ports also demonstrated exceptional performance, exceeding 1,700 MB/s in single-threaded tests. These results underscore the NAS’s ability to handle high-demand workflows like video editing and real-time collaboration.

Thermal management is a crucial consideration for SSD-based NAS devices, and Asustor has made notable efforts in this area. The Flashstor Gen 2 employs dual cooling fans, one dedicated to the CPU, as well as copper heat pipes to dissipate heat from the M.2 NVMe slots. These measures effectively manage the heat generated by the Gen 4 SSDs, which maintained stable temperatures during intensive use.

However, some limitations remain. The top-mounted M.2 drives lack active cooling, resulting in localized heat buildup during prolonged usage. While temperatures remained below critical thresholds during testing, the absence of heat sinks for the M.2 slots is a noticeable drawback, particularly for users planning continuous heavy workloads. Asustor could address this with an included cooling solution to better accommodate the higher heat output of Gen 4 drives.

Power consumption during operation was modest, averaging 32.2W and peaking at 56W under load. Coupled with the efficient thermal management and quiet operation, these characteristics make the Flashstor Gen 2 a solid choice for 24/7 use in professional environments where noise and energy efficiency are priorities.

Flashstor Gen 2 Storage Configuration and Lane/Speeds

The storage configuration of the Flashstor Gen 2 offers immense potential, with 12 M.2 NVMe slots enabling substantial storage arrays. However, the allocation of PCIe speeds across these slots is uneven, leading to a complex setup process. The slots are divided as follows:

• 1 x Gen 4×4
• 3 x Gen 4×2
• 4 x Gen 4×1
• 1 x Gen 3×4
• 1 x Gen 3×2
• 2 x Gen 3×1

This configuration allows for flexibility but also introduces challenges for users seeking uniform performance across RAID arrays. It is more practical to configure the drives into multiple independent pools rather than a unified array, as the differing speeds can create bottlenecks. For users planning large-scale data storage, careful planning of drive allocation will be essential.

Despite this complexity, the performance of individual slots was impressive. Single 10GbE connections were fully saturated during file transfers, while multi-channel configurations demonstrated even greater throughput. Testing with dual 10GbE connections showed that the device could handle heavy data loads across different RAID pools simultaneously.

For professionals with demanding storage requirements, the Flashstor Gen 2 offers the capacity and speed to meet their needs. While the mixed PCIe speeds might deter some users, those with the technical expertise to optimize configurations will find significant performance benefits.

Flashstor Gen 2 Ports and Connections

The Flashstor Gen 2 offers an impressive array of ports, catering to a variety of workflows and setups. The device includes dual 10-Gigabit Ethernet ports, two USB 4.0 Type-C ports, and three USB 3.2 Gen 2 Type-A ports, ensuring ample connectivity for both networked and direct-attached use cases.

The dual 10-Gigabit Ethernet ports provide high-speed networking capabilities, supporting SMB multichannel for simultaneous data streams. This feature is especially useful for collaborative environments or workflows requiring simultaneous access by multiple users. During testing, the dual connections consistently delivered excellent throughput, making them ideal for demanding tasks such as video editing or real-time data processing.

The USB 4.0 Type-C ports are a standout feature, offering 20Gbps speeds each. These ports enable high-speed direct access to the NAS, expanding its use cases to include direct-attached storage scenarios. Testing showed that these ports performed exceptionally well, with transfer speeds exceeding 1,700 MB/s, making them a valuable addition for professionals needing rapid data access.

The three USB 3.2 Gen 2 ports add further versatility, supporting 10Gbps speeds for external storage devices or additional peripherals. Together, these ports create a highly adaptable system capable of integrating seamlessly into diverse workflows. Whether used for networking, direct storage access, or peripheral connections, the Flashstor Gen 2’s ports make it a flexible and powerful tool for professionals.

Asustor Flashstor Gen 2 NAS Software – ADM5

The Asustor AS6812X NAS arrives with the latest version of ADM 5 included. Additionally, this software receives frequent updates to ensure that the software runs the very best it can on the Lockerstor, as well as keeping up to date with security patches and application versions. The NAS software is accessible via a web browser and displayed very much like a normal computer operating system (desktop, user accounts, customizable themes, file management, running multiple tasks in windows that can be switched in the native tabs), but there are also a range of desktop client tools for accessing the NAS on your local machine natively, as well as a whole bunch of mobile applications that allow tailored access from your phone/tablet in more task-specific means (eg a photo app for viewing pictures and creating phone backup routines, a video app for enjoying your movies and boxsets, surveillance app to access your cameras, etc).  There is also a large range of support of 3rd party applications too in the ADM platform. Asustor is not as big a company as the likes of Synology and QNAP, whole put ALOT more money into their software development, but Asustor try to counter this by (when they do not have an in-house app) making native versions of 3rd party tools in their platform (example, they do not have a 1st party Virtual Machine app, but DO include huge support for VirtualBox). The platform is not quite as fully featured as DSM and QTS, but it is still a very smooth and accessible software platform. The app center has a few more 3rd party applications and slightly crowbarred software (eg the Amazon Media and Streaming service plugins) that is not updated up the original uploaders anywhere near enough (leading to running issues on these tools), but the 1st party apps run very well. The big takeaway on the Asustor software and it’s services is that the standard class of expected features of a modern NAS in 2024/2025 are here and run exactly as you would want, it is just some of the additional ones that other platforms have doubled down on (such as AI-related services in Photography and Surveillance for example) that are a little lacking. That said, the brand has definitetl ramped up a number of the key security protocols and settings in the default setup.

These are just the tip of the iceberg and I will be going into more ADM 3.4 and AS6812X applications in the Software Review.

Here is how the Asustor ADM platform compares with the Synology DSM platform:
