– Asustor FLASHSTOR 6 Gen2 FS6806X 6-Bay M.2 SSD NAS Network Memory, AMD Ryzen Quad Core 2.3GHz, 8GB DDR5 RAM, 6 M.2 SSD Slots, 10GbE Port, USB4 Type-C, Connected Network Storage

I bought the Asustor FLASHSTOR 12 Pro Gen2 FS6812X to consolidate all my scattered USB drives and multiple storage setups into one fast, centralised system—and it’s been a fantastic upgrade. Here’s what stands out: I installed six 4TB NVMe drives and set them up in RAID 5, giving me around 20TB of usable space with redundancy. 12 x M.2 SSD slots offer massive potential for future expansion, and make this NAS totally silent—no spinning disks here. Dual 10GbE ports provide blazing-fast transfer speeds—file moves and backups are quick and effortless. The Ryzen Quad Core 2.3GHz CPU and 16GB ECC DDR5 RAM handle everything smoothly, even under load. The Asustor OS is clean and powerful with great tools for backup, media, Docker, and more. USB4 Type-C is a nice touch for external device access. Yes, it’s on the expensive side, but with these specs and performance, I think it’s worth every penny. If you’re looking for a high-performance NAS with tons of SSD storage potential, excellent speed, and a future-ready setup—this is it.

Don't let the weird PS4 shape put you off, also the rather plasticky build. The device itself is super easy to use, from the installations of the NVME drives (toolless), and upgrading the memory. I upgraded mine to 16gb using some Crucial (https://www.amazon.co.uk/dp/B08C4WV6FT?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1). The downloadable ASUSTOR Control Center app made installation of the NAS a breeze. The interface is snappy and quick on 16gb. The official heatsinks are a little overpriced (https://www.amazon.co.uk/dp/B0CFTYRK3J?ref=ppx_yo2ov_dt_b_fed_asin_title) and should really have been included. I would recommend some sort of heatsinks for keep things cool. Just be careful if you intend to add NVME drives with existing heatsinks as they might too tall and may obstruct the cooling fan or worse still prevent you from putting the fixture plate back on. Across a 2.5gb link, I've managed to saturate the available bandwidth reliably and consistently. The app store although not the same level as QNAP or Synology, has some of the most common apps available, so not felt as though I missed out using ASUSTOR ADM. Overall, pleased with the device and as a Flash NAS is makes a compelling reason to ditch the mechanical equivalents, although it will be far more expensive to populate.

Great item silent running, easy to setup and attractive too. As they are SSDs fast and reliable. Absolutely no issues. Now just got to get a handle on Plex!

Already running two Synology NAS setups. following several drive failures I was keen to get going on SSD NAS drives. This device is spot on, though initially, I struggled to get one through lack of stock, when it arrived it was worth the wait. A couple of things you need to consider though! In at number 1 is the SSD's, the temptation, of course, is to go a little cheaper but increase your storage capacity, but speed plays a huge part, I ended up going with some nice intel SSD's that were on offer, now I am getting huge throughput copying close to 150 Mb's over the network, so please think about what you are going to put inside of it. In at number 2, the interface. This of course is subjective but being used to DSM, I found the ASUS GUIi a touch clumsy and sometimes slow, other people I am sure will disagree but I think its a fair comparison, with that said it does everything you would expect and though not always obvious you should find no big differences. Overall its a slick looking device, perhaps a little Media player looking compared to a synology, but who cares?! It will sit somewhere happily churning out data to your network. I would 100% recommend this, it's expensive to get started but you won't regret it. My only regret is I didn't buy the 12-bay version but hindsight is a wonderful thing.

Fantastic system, be prepared to spend some money on the SSD's but you'll be aware of that if purchasing this system. Works really well, I only use basic features do haven't delved into the numerous apps available. Never expereinced any drop outs or overheating, although I did purchase the heatsinks for the SSD's which IMO should be included.

Using 6 no. Samsung 2TB EVO Pro and maxing out the network connections; JBOD though as do not wish the capacity reduction and it is not my main NAS. Works perfectly, no issues and virtually silent. Application software is fine and easy to use.

software is Glitchy and no customer service in the UK

As someone working in the visual effects industry, I was genuinely excited to try the ASUSTOR Flashstor NAS. The hardware specs is impressive, 10GbE connectivity, and an SSD-only architecture make it an appealing choice for content creators and professionals dealing with large media files. The promise of performance, particularly for workflows involving sequential files like EXRs or image sequences, is what drew me in. ASUSTOR's marketing highlights this as being suitable for 4K editing and content creation, and I do believe the potential is there. However, after months of real-world testing across various system configurations, operating systems, and network environments, I encountered persistent performance inconsistencies. What I Tried: Multiple fresh installs of Windows (Home, Pro, Pro N, LTSC, and debloated variants) Swapping between ECC and non-ECC RAM Comparing different 10GbE NICs, including the one recommended by ASUSTOR Using tools like iperf3 and AJA System Test to monitor throughput Testing with SMB, NFS, and even attempts at running alternative NAS OSes Despite my efforts, performance would sometimes drop inexplicably. Transfers of 20GB+ EXR sequences could take hours under certain conditions, and at times, AJA tests would stop responding altogether. While large single-file transfers worked well and could saturate the 10GbE link, the NAS seemed to struggle under workloads that involved thousands of sequential frame reads/writes—something very common in VFX and post-production. To be fair, ASUSTOR's support team was responsive and polite throughout, and I truly believe they care about improving the product. I also want to highlight that in many editing scenarios (e.g., ProRes or large single video files), this NAS might perform excellently. But for artists working with dense image sequences and multi-user render farms, your mileage may vary. Why two Stars? The hardware is solid and well thought out. The vision behind the product is admirable—making high-speed SSD NAS accessible to professionals and enthusiasts. The performance just didn’t match expectations in my use case, despite extensive troubleshooting. I'm giving ASUSTOR the benefit of the doubt that with firmware/driver updates, this unit could evolve into something exceptional. If you're a content creator working with large video files, this might still be a great solution. But if you're in VFX, 3D, or any workflow that relies on reading thousands of files rapidly (e.g., EXR, DPX, or image sequences), you may want to do additional research—or wait for software/driver improvements. I’m still rooting for ASUSTOR. The enthusiasm and ambition behind their products, and I hope future revisions will take feedback like this onboard.
