Our Review

The Asustor Flashstor 6 FS6706T, priced at £429.00, presents an intriguing option for those seeking high-performance NAS solutions with its all-SSD configuration. With a rating of 4.2 out of 5 from 349 reviews, this device is designed for users who prioritise speed and efficiency in data storage and management. The Flashstor 6 features a quad-core Intel Celeron N5105 CPU, which runs at 2.0 GHz, making it capable of handling demanding tasks such as 4K video transcoding and multiple simultaneous user access.

Key Features in Detail

The Flashstor 6 stands out with its six M.2 NVMe slots, allowing users to install multiple SSDs for high-speed data access and transfer. This is complemented by dual 2.5GbE ports, which facilitate faster network speeds compared to traditional Gigabit Ethernet setups. The device also comes equipped with 4GB of DDR4-2933 RAM, which can be expanded for those who need more memory for intensive applications. With support for HDMI 2.0b, users can connect the NAS directly to a display, making it versatile for media consumption.

Performance Assessment

In terms of performance, users can expect lightning-fast data retrieval and smooth streaming capabilities, particularly beneficial for Plex server setups or high-demand environments. The hardware transcoding feature ensures that 4K content can be streamed to devices without hiccups, making it a fantastic choice for home theatres or digital entertainment centers. Notably, the Wake on WAN and LAN features allow remote access and management, enhancing its usability for remote workers or tech enthusiasts.

Build Quality

The build quality of the Flashstor 6 is robust, featuring a well-ventilated chassis that keeps the SSDs cool during prolonged use. The design is user-friendly, making installation straightforward for those familiar with NAS setups. However, it is worth mentioning that the unit is diskless, meaning users will need to purchase SSDs separately, which can add to the overall cost.

Value for Money

At £429.00, the Asustor Flashstor 6 is competitively priced, especially considering its features and performance capabilities. It is currently at an all-time low, with a 4% discount off the list price of £449.00. In comparison to alternatives such as the Synology DS224+ priced at £466.64, the Flashstor 6 offers superior performance for similar pricing, particularly for users focused on SSD technology.

How it Compares to Alternatives

When compared to the Synology DS223J, which retails for £179.97 but offers significantly fewer features and lower performance (2-bay vs. 6-bay), the Flashstor 6 is clearly more suited for power users or those needing extensive storage capabilities. Additionally, while the Buffalo LinkStation 210 provides a budget-friendly option with included HDDs, it lacks the performance and speed that SSDs deliver, making it less suitable for high-demand applications.

Genuine Weaknesses

One of the notable weaknesses of the Flashstor 6 is the lack of included storage — users must invest in SSDs separately, which can significantly increase initial costs. Additionally, while the performance is impressive, the unit's relatively low RAM could pose limitations for users needing extensive multitasking capabilities unless upgraded. As with any device, users have reported occasional software bugs, which may require updates for optimal operation.

Verdict

The Asustor Flashstor 6 FS6706T is a strong contender in the NAS market, especially for users who prioritise speed and performance. It's ideal for tech enthusiasts and professionals looking for a high-performing storage solution, though those on a tighter budget should consider cheaper alternatives or be prepared for additional costs to equip the device with SSDs.
