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 had a Synology DS220+ before this one, and I was getting realy tired how much noise it was making with its spinning HDDs even though I put it in a closet and added some sound proofing you would hear it making noises, so I have been looking for quite some time to upgrade to a full SSD NAS and after a lot of thought I decided on this Flashstor from Asustor and I was a bit worried that from what I heard that Synology DSM is so userfriendly and good and no other NAS comes close to to Syno software. That is so wrong, I frigging love Asustor ADM. it feels really good and I have no problems navigating it. And finally no more HDDs sound from the closet, all silent and nice. And the speed of the SSDs setup is just so good, my NAS is now finally super responsive and I feel like I can host more things on it and realy use.

I have been running a plex server for years on my desktop PC. I got the dreaded message from MS that Windows 10 was dying soon and my PC did not meet the minimum requirements to run Windows 11. I have been looking at NAS solutions like Synology and QNap. While these are definitely an option, I ran across the ASUStor on Amazon and then jumped to YouTube to do some research. Thank you guys over at NASCompares! Great info and guidance. Then I discovered how much SSD prices have fallen and well, decision made! I dove in to this ASUStor Flashstor Pro Gen 2! I chose to go with six 4TB drives in raid 5 to start with. Still have 6 slots that I can expand into for future needs! I chose to go with the ASUStor heat sinks for an additional $29 and 6 TeamGroup MP44 4TB SLC Cache gen 4x4 SSD drives to round out my initial setup. First I have to say, make sure you cross reference the drives you choose, with the ASUStor compatibility guide online. This is critical. Next, the Flashstor 12 Pro Gen 2 was super easy to open up and add the drives and heat sinks to. Took about 10 minutes total and boom, powered on and ready to rock and roll. Quick note here, you may want to log into your router and find the DHCP address assigned to your Flashstor, you will need this so you can connect to the web interface! Setup was super quick with the ASUStor ASM! This software is freaking amazing and very intuitive! It basically walks you through the process to get your drives configured and they have their own App Store! Super easy to find apps you will need. It has everything from Container Software to back up software to streaming media software. Amazing job here ASUStor! Be warned, 24Tb of SSD is a lot, even with the AMD Processor, it is gonna take awhile to complete. Good news though, you can actually start loading the apps you want while it is doing its thing after a certain % complete on the raid! Nice touch there! Again, my plan was to replace my aging PC I stream Plex from. Here is where it gets a little frustrating, the Plex App was difficult to actually get working. So much so, that as I dug in on researching the issue, I discovered that Plex actually generates a ton of bloated traffic on your network! What the heck Plex!? I have a lifetime pass with them, but this really made me second guess my choice of Plex… yep I wound up switching to Jellyfin and the Flashstor had the app available in their store and it was super quick and easy to setup and get running. Again, phenomenal job here on third party apps and availability in your ASM tool! The quality of this hard ware is amazing! It feels pretty well made and they have done a lot to dissipate the heat in a passive system! They have built in monitoring in the ASM and you can track the health of your raid(s) with real time temperature monitors for the SSD and Processor. They offer dual 10gb Ether ports and ECC RAM support. The RAM comes at 16gb (single stick) with the initial device. This is easily expandable to 32gb, and I recommend you jump on that quick! It will really improve streaming performance when you get a few people in your house streaming to their various devices. This thing is super quiet too! Say goodbye to jet engine sounding NAS in your house! This bad boy is so quiet! Benefits of no mechanical drives and massive power requirements! To sum this up, I was very impressed by this device and would recommend to anyone looking to venture out into the world of NAS for backup solutions and/or streaming. A little bit pricey for the initial setup, but you can grow as you go and need because of the expandability this device offers!

全スロットNVMe SSDのみ対応なのでR/W性能は非常に高いです。 ただ、高い製品の割に外装がプラスチックで安かったり、 SSDの固定がツールフリーではありますが、固定具もプラスチックで安っぽく長期運用で使うには不安が残ります。 各NVMeスロットのレーン数の分配も正直微妙で、 10GbpsはPCIe Gen4 *2 以上であれば1スロットで速度が事足りるので、 PCIe Gen4 *4スロットのレーンをPCIe Gen4 *1に割り当てて、 PCIe Gen4 *2スロットを増やしてほしかったです。 もしくは動的にレーン数を変更出来るようにしてくれる方が便利だと思います。 高速ではありますが、価格には見合っていない品質と設計だと思います。

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.

This is not a stable product, that you should buy, if you expect the thing to just work. It fails randomly in catastrophic ways and requires knowledge and experience of Linux to fix. After humming along for a few weeks the machine suddenly decided to shut down. After being turned on again all my files were gone. The disks were visible, but marked as "inactive" and there were zero options to recover this through the web browser. In the end, after logging in with a text terminal and spending two hours digging through configuration files I was able to re-activate my disks, by manually editing a configuration file, that the system had overwritten with incorrect information. I was replacing my home built NAS, because I wanted to get away from all the work involved in maintaining and configuring a Linux server, and now I have this junk instead, which is another Linux server that I have to maintain, because it's so poorly setup.
