I have been a long time user of a competitors product. I needed to add another NAS to my home/small business office network. I do a lot of photo editing and some video editing and need to back up my work to a very reliable NAS. After careful research I concluded that the ASUSTOR Lockerstor 2 Gen2 AS6702T (2-bay unit) was the best NAS to meet my needs. The unit received high reviews from third parties and it lived up to the hype. PROS- Fast file transfers (much faster than my older NAS) Dual multi-gig LAN ports (but of not value to me since my LAN supports 1000mbs only) Four slots for M.2 NVMe SSDs (for storage or caching but not both) Expandable Large catalog of apps both from the manufacturer and third parties CONS- Expensive Expanding RAM to 16GB requires disassembling the unit (although the manufacturer has a step-by-step video to guide you through the process, and I did upgrade to 16GB and found the video helpful) Setup was easy (except for the memory upgrade installation which took about an hour). I installed 2 10TB HDDs and was up and running in less than 15 minutes. File transfers from my desktop were speedy. Besides my desktop I use an apple laptop as well as a windows laptop on my LAN and they have no problems accessing and using the NAS. I strongly recommend using a UPS with this unit. I would not recommend enabling remote access to the ASUSTOR from the internet unless you are very well versed in the security issues involved, especially using VPNs. I have been using the unit for over a week and so far I am very pleased with its performance. Recommended.

I've been using the second-generation Asustor AS6702T for about a month, and it’s exceeded my expectations in every way. It’s become the backbone of my home infrastructure, handling multiple roles with ease: • Primary NAS: Hosts 3.5 TB of shared storage via SMB and NFS. • Media Server: Runs Jellyfin for streaming audio, video, and photos. • Web Server: Serves personal websites reliably. • Centralized Logging: Collects logs from my Wi-Fi routers and Linux machines. • Backup System: Automatically backs up data to an attached 4 TB external drive. And that’s just scratching the surface. The AS6702T supports VPN, Docker, VirtualBox VMs, and custom scripting in Python or Shell. It also runs PHP and Perl, though I haven’t explored those deeply. Upgrade Tips Out of the box, the 4 GB of RAM is a bit limiting. I upgraded to 8 GB (the max supported), which required partial disassembly—but it’s far easier than building a PC. I also added 2×512 GB SSDs for caching, which noticeably improved access speeds. Why I Chose AS6702T Over Other NAS Units • Solid build quality • Robust Linux-based ADM 5 OS, accessible via web portal or SSH • Expandable with 4 M.2 slots • Dual 2.5 GbE ports for fast networking • No forced cloud integration—your data stays yours • Two USB 3.0 ports with one-touch copy for easy backups Compared to my older WD MyCloud, this feels like a personal datacenter. File transfers hit 280 MB/s, which is blazing fast for a home setup. Final Thoughts If you’re considering this NAS, I highly recommend investing in the RAM and SSD upgrades. It takes a bit of effort, but the performance gains are absolutely worth it. Also, install a robust HDD—go for something like the WD Red series or Seagate IronWolf. These drives are built for 24/7 operation. IronWolf pairs especially well with this NAS thanks to a dedicated app for monitoring drive health and performance.

The support for this product is less than helpful. They constantly close tickets without resolving the issue, and there is no way to review the support. Support is important especially since I have found that many of their apps do not work or have major bugs. The following apps were found not to work: the antivirus software frequently fails. The SSH app to access the NAS command line does not work. The app to sync data with cloud services such as OneDrive actually overwrites your data even when set up to be a one direction sync (say good by to your data). The hardware is excellent but I have found the software to be for the most part unusuable. I've had to find workarounds for almost every piece of software they provide. It's completely unacceptable and they should not be putting out software that can corrupt your data, and should be providing support and addressing issues instead of closing tickets without resolution of the issue first.

Overall this NAS is excellent. The build quality is fantastic, the device runs perfectly, and it's pretty quite. One point of major concern if you're planning on hosting public-facing things is the continued ransomware attacks on ASUSTOR NAS systems. It seems like the company is trying to figure out how to defend against it, but it's slow. Mine hasn't been hit, but I disabled all public-facing capability (and manually blocked outside access at the router). It seems like it's their EZ solution that's the problem. They now require that you change the port if you're doing a fresh setup, but that's not a fix. They need to address this. For now I don't feel comfortable putting any part of it out on the internet. So if you want to get this for any kind of web hosting, don't risk it for now. Internally on my network it works beautifully. I bumped it up to 16GB of RAM (mostly for virtual machines). Accessing the inside RAM slot is tedious, but not terrible. I wish they made it a little easier to get to. My Plex server runs on this without any problems. I usually run 3 virtual machines, plus a few Docker things, and I never notice any slowdown or drops, even when 2 Plex streams are running (I don't usually do much transcoding, so it doesn't impact the CPU much). The setup takes a little time to tweak everything to how you want it, but I'd prefer more settings that I can control to only a few settings and everything else hidden or unable to be changed.
