Asustor FLASHSTOR 12 Pro Gen2 FS6812X, 12 Bay All M.2 SSD NAS, AMD Ryzen Quad Core 2.3GHz, 16GB RAM ECC DDR5, 12 M.2 SSD Slots, Dual 10GbE Port, USB4 Type-C, Network Attached Storage (Diskless)

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.

Perfect

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

The concept of an all ssd prosumer NAS is great especially as SSD prices are coming down. I have started off with 4 lexar 4TB drives for this one. The NAS is lightning fast and limited mostly by the CPU if you are looking for speeds over 5gbps. Unfortunately, the build quality is not great and this looks and feels cheap. Why design it like a PS2? Worse, you need to remove 4 screws to get to the ssd slots and these screws are a pain. They don’t seem to be standard ones and I ended up striping them. Managed to extract them after drilling in. Decided not to use any more screws as the USB connection (for the fan!) provides a tight enough lock for something that sits in my server rack.

Es caro paro es justo lo que buscaba.

Appareil défectueux expédié (à mes frais !) en Hongrie il y a un semaine. Aucun nouvelle depuis ! Instructions de retour contradictoires. Le colis se trouve à présent à Budapest où, bien entendu, ils ne savent qu'en faire ! Pour un matériel de plus de 1000 euros + frais d'achat de NVME et de mémoire, c'est très, très décevant ! La solution la plus simple à ce problème serait de m'envoyer un nouvel appareil QUI FONCTIONNE !

I'm able to consistently saturate the 10Gbe both R/W with 6x TeamGroup MP34 4TB NVMe drives on BTRFS Raid5. ADM works fine and easy to use. All services (SMB, NFS, AFP, etc.) are perfectly working with 0 downtime. I have it placed in my rack in a high-ambient temp area and drives never go over 42C. I purchased the heat sink kit from Asustor separately to make it easier to manage heat under load while manually setting the fan speed to High in ADM. It's been rock solid the past few weeks and consistently giving me top speeds and I haven't filled the array yet. Definitely enjoying the low power consumption as well. What really impresses me is the random seek being so fast as you would expect from NVMe. This is a pretty unique product that I passed over at first glance, but after more research and actual use I'm finding it being a centerpiece of the homelab giving me fast IO for a pretty good price. NVMe speeds, 10Gbe, low-power consumption, small form factor, intel processor, upgradable ram and quiet all at a pretty good price point with the added benefits of better random seek. I struggle to compare to any commodity gear that has all these features for that price. Really excited to see what other devices this inspires with the NVMe prices falling, but for now this is a solid & fast NAS.

Funciono como debe Le puse 2 diferentes marcas diferentes de nvme Kingston Acer Al principio le puse 6 nvme de la marca kingston en raid 5 le transferi mi información de otro almacenamiento que tengo a los pocos días compré 5 nvme acer y ya tenía un nvme acer así que le agregué los otros 6 más y en el administrador del raid lo actualicé y ahora tengo 40 tb de almacenamiento disponible Precaución cuando hagas el raid espérate hasta que esté creado ya que lo tengas creado ahora si instalas las aplicaciones que vas a usar Crea los usuarios Crea tus carpeta Transfiere tus datos Si estoy considerando comprar más ram y los disipadores para los nvme 4 gb de ram no es suficiente Amazon deberia de darte el combo de memoria y disipadores pero bueno es algo para el futuro

FS6712XとFS6707Tの両方を 10GBのLAN環境でメモリ16GB、2TBのSSD6本と12本のRAID5で利用しています。 FS6707T LAGRound‐Robinで利用なのでSEQ読出しは600MB/sで書込みは300MB/sでます。 こっちに10GBのLAN搭載されていればベストバランスかも知れません。 FS6712X SEQ読み書きは1200MB/sでます。 M.2はGen3でもGen4でも低発熱チップのSSDの選択を強く推奨します。 筐体が樹脂なので放熱性能は低いです。（下部にファンが付いるので上段のSSDは冷やせません） ※読み書き中は60℃を超えるSSDが12本も入っているので、これは仕方ないです。 ADMという基本OSの更新ありますがアプリは1～2年以上更新が無いものがほとんどです。 同期系のアプリ、DataSyncとEzSyncなど便利そうなアプリはありますが ファイルが大量にあるとエラー吐きまくるので改善して欲しいです。 他社製品のようにアプリでいろいろやりたい場合は残念な結果になるのでお勧めできません。 特に自動同期して利用するBackUp用途には不向きです。 もう少し更新頻度上げて、アプリの同期処理など頑張って改善して欲しいところです。 HDDの騒音が無く、薄くて軽くて、LAN環境に合わせた速度が出るのが最大の利点です。 USB3.2Gen2のポートが両機種とも2つあり2本ずつUSB3.2接続して外部機器として利用います。 こちらもシーケンシャル1200Mb/sで利用でき、ネットワークドライブ登録も可能です。 同期でエラーや不具合が多く利便性は低い製品なのでお勧めはできません。 2.5GBまでのLAN環境ならHDDで良いと思います。 Asusの子会社なのでもう少し頑張って欲しいです。 ※加筆 2024/9/26にADM更新と一緒にDataSync他、多くのアプリ更新きました 同期がどうなるかは様子見中です → 1週間エラーでずっと同期中でしたが止まりました 対応が早かったので星一つ追加です 2024/10/11 SMBバックアップの次回のスケジュールが延々と過去日です。 いまのところ、本来の目的であるバックアップ用途には不向きな製品です。 星一つマイナスです。
