Asustor FLASHSTOR 6 Gen2 FS6806X: Unleash the Power of All-Flash NAS Storage

We live in an age of unprecedented data creation. High-resolution photos, 4K (and even 8K) videos, sprawling game libraries, and ever-growing music collections – our digital lives are expanding at an exponential rate. This “digital deluge” puts immense pressure on our storage solutions. We need more space, yes, but we also need that space to be fast. Waiting hours for files to transfer or experiencing stuttering playback of high-bitrate video is simply unacceptable in today’s fast-paced world. This is where Network Attached Storage (NAS) comes in, and more specifically, a new breed of NAS: the all-flash NAS.

From Spinning Disks to Flashing Lights: The Evolution of NAS

For years, NAS devices were synonymous with bulky boxes filled with spinning hard disk drives (HDDs). Think of a traditional HDD like a vinyl record player. A physical arm (the read/write head) has to move across a spinning platter to access the data. This mechanical process, while reliable for large-capacity storage, is inherently slow. Early NAS systems were primarily used for basic file sharing and backups, where speed wasn’t a top priority.

As technology advanced, so did NAS. Faster processors, more RAM, and improved network interfaces helped boost performance. But the fundamental bottleneck remained: the spinning hard drives. The solution? Replace them with solid-state drives (SSDs).

All-Flash NAS: What Makes it Different?

SSDs, unlike HDDs, have no moving parts. They store data on flash memory chips, similar to the technology used in USB drives and smartphones. This fundamental difference translates to several key advantages:

• Blazing Speed: SSDs can read and write data significantly faster than HDDs. This means faster file transfers, smoother video playback, and a more responsive overall experience.
• Near-Silent Operation: Without spinning platters and moving heads, SSDs are virtually silent.
• Lower Power Consumption: SSDs use less power than HDDs, which translates to lower energy bills and reduced heat output.
• Compact Size: SSDs, especially the M.2 form factor, are much smaller than traditional HDDs, allowing for more compact NAS designs.

Meet the Asustor FLASHSTOR 6 Gen2: A Compact Powerhouse

The Asustor FLASHSTOR 6 Gen2 FS6806X embodies the all-flash NAS revolution. It’s a sleek, compact device that eschews traditional spinning hard drives in favor of six M.2 slots designed for high-speed NVMe SSDs. This design choice immediately sets it apart, offering a level of performance previously unattainable in such a small form factor. Combined with a powerful AMD Ryzen Embedded processor and support for high-speed networking, the FLASHSTOR 6 Gen2 is designed for users who demand the best possible storage performance.

Under the Hood: Decoding the Tech

Let’s delve into the key technologies that make the FLASHSTOR 6 Gen2 such a speed demon:

• NVMe SSDs: The Speed Demons of Storage: NVMe (Non-Volatile Memory Express) is a protocol specifically designed to take advantage of the low latency and high bandwidth of SSDs. Think of it as a language that allows the SSD to communicate with the rest of the system much more efficiently than older protocols like AHCI (which was designed for HDDs). Imagine AHCI as a two-lane country road, while NVMe is a multi-lane superhighway. The result? Significantly faster data access.

• PCIe 4.0 x4: The Data Superhighway: PCIe (Peripheral Component Interconnect Express) is the interface that connects the NVMe SSDs to the motherboard. Think of it as the physical road that the data travels on. PCIe 4.0 is the latest generation, offering double the bandwidth of PCIe 3.0. The “x4” indicates that four lanes of PCIe are used, maximizing the potential throughput. Combining NVMe with PCIe 4.0 x4 is like having a super-fast car on a wide-open, multi-lane highway – data can flow incredibly quickly.

• 10 Gigabit Ethernet: Breaking the Network Bottleneck: Even the fastest storage is useless if your network can’t keep up. The FLASHSTOR 6 Gen2 includes a 10 Gigabit Ethernet (10GbE) port, providing ten times the bandwidth of traditional Gigabit Ethernet (1GbE). This is essential for tasks like 4K video editing, where massive files need to be transferred quickly and efficiently. To take full advantage of 10GbE, you’ll need a compatible switch and other devices on your network that also support the standard. It can make a big difference to a home network.

• USB4: The Future of Connectivity (with a Caveat): The FLASHSTOR 6 Gen2 includes two USB4 ports, offering potentially blazing-fast transfer speeds. USB4 is based on the Thunderbolt protocol and promises speeds up to 40Gbps. However, it’s critically important to understand the current
  limitations. Asustor clearly states that, at the time of writing, the AMD USB4 driver used in the FLASHSTOR 6 Gen2 (and the Lockerstor Gen3 series) only supports connections to external storage devices and direct connections to another Lockerstor Gen3 or Flashstor Gen2 NAS. This means you cannot directly connect a Mac (or any non-Asustor device, for that matter) via USB4 and expect to access the NAS’s storage at high speeds. This is a significant limitation, particularly for Mac users who might expect Thunderbolt-like functionality. While future driver updates might address this, it’s a crucial consideration for potential buyers.

• ECC RAM: Upholding Data Integrity: The FLASHSTOR 6 Gen2 supports Error-Correcting Code (ECC) RAM, a feature often found in servers and workstations. Unlike standard RAM, ECC RAM can detect and correct single-bit memory errors. These errors, while rare, can be caused by various factors like background radiation or electrical interference. In a standard system, a single-bit error might go unnoticed, potentially leading to data corruption or system instability. ECC RAM prevents this, adding an extra layer of reliability and data integrity. This is particularly important for a NAS, which is often entrusted with critical data.

ADM: The Brains of the Operation

The Asustor Data Master (ADM) operating system is the software that powers the FLASHSTOR 6 Gen2. It’s designed to be user-friendly, even for those who aren’t networking experts. ADM provides a web-based interface accessible from any computer or mobile device on your network. Key features include:

• Intuitive File Management: ADM’s File Explorer provides a familiar interface for managing your files and folders, similar to what you’d find on a Windows or macOS computer. You can easily create folders, upload files, download files, and share files with others.

Real-World Applications: Putting the FLASHSTOR 6 Gen2 to Work

The FLASHSTOR 6 Gen2’s speed and versatility make it suitable for a wide range of applications:

• Home Entertainment Hub: 4K Streaming and Beyond: Imagine streaming multiple 4K movies simultaneously to different devices in your home, without a hint of buffering or stuttering. The FLASHSTOR 6 Gen2, with its fast NVMe SSDs and 10GbE network, makes this a reality. You can store your entire media library on the NAS and access it from any device, turning your home into a true digital entertainment hub.

• The Small Office/Home Office (SOHO) Solution: Collaboration and Backup: For small businesses and home offices, the FLASHSTOR 6 Gen2 provides a centralized location for storing and sharing files. Multiple users can access the NAS simultaneously, making collaboration on projects much easier. The robust backup features ensure that critical business data is protected from loss.

• Content Creation Powerhouse: Video Editing, Photo Processing, and More: This is where the FLASHSTOR 6 Gen2 truly shines. Content creators often work with massive files – raw 4K or 8K video footage, high-resolution RAW photos, and large design files. The speed of the FLASHSTOR 6 Gen2 allows them to edit these files directly from the NAS, without having to copy them to their local workstation first. This dramatically speeds up their workflow and improves productivity. The support of RAID levels offer the needed flexibility.

• Snapshot: Keeping Data Safe
  Snapshot Center is a feature for ASUSTOR NAS devices to utilize Btrfs and iSCSI volumes to take snapshots of the information inside a NAS. Snapshot Center supports up to 256 snapshots of a volume. Think of snapshots as “restore points” for your data. If you accidentally delete a file or make a mistake that corrupts your data, you can easily revert to a previous snapshot, restoring your files to their previous state. The ability to take snapshots every five minutes provides a high level of data protection, especially useful if you ever get ransomware.
  

Case Study: A Video Editor’s Journey to Faster Workflow

Let’s revisit Sarah, our freelance video editor, but this time with more technical detail. Sarah shoots 4K footage using a professional camera, generating massive ProRes files. Her old workflow involved copying these files from her camera’s media cards to an external hard drive, then copying them again to her computer’s internal SSD for editing. This process was incredibly time-consuming.

With the FLASHSTOR 6 Gen2, Sarah’s workflow is streamlined. She connects her camera’s media card reader to one of the NAS’s USB 3.2 Gen 2 ports. She utilizes ADM’s file management tools to quickly transfer the footage directly to the NAS, setting up a RAID 5 configuration across her six NVMe SSDs for both speed and redundancy (RAID 5 allows for one drive to fail without data loss).

Now, here’s the key difference: Sarah can open her video editing software (let’s say Adobe Premiere Pro) and directly access the footage on the NAS. The 10GbE connection between her computer and the FLASHSTOR 6 Gen2 provides enough bandwidth to handle the high data rates of 4K ProRes video. She can scrub through the timeline, apply effects, and render her final project without any of the lag or stuttering she experienced with her old setup.

Furthermore, Sarah utilizes ADM’s Snapshot feature. She sets it to take snapshots of her project volume every hour. This provides an extra layer of safety. If she accidentally deletes a clip or makes an editing mistake, she can easily revert to a previous snapshot, saving her valuable time and effort. And thanks to Asustor’s 3-year warranty, she also rests easy knowing that the hardware is protected.
