Asustor Lockerstor 6 Gen2 AS6706T - 6 Bay NAS, Quad-Core 2.0 GHz CPU, 4X M.2 NVMe Slots, Dual 2.5GbE, Upgradable to 10GbE, 8GB DDR4 RAM, Content Creation Network Attached Storage (Diskless)

This Asustor NAS exceeds my requirements. It was purchased to replace an older Netgear NAS and I am not disappointed. I found the learning curve was easy. High quality with excellent connectivity. In addition to using it to store backups for 6 computers, I use to store duplicate files.

I have TWO of these things because the price is so sweet (looking at you synology) - so 20 drives in total.First thing I've done in all of them - install RAM (up to 64 GB) and SSDs (two). These devices have a read/write SSD cache mode which I find unimpressive - it's okay, you can set up the SSDs as a separate high speed array and I recommend that.The 10gbit LAN connections have worked without issue. The i/o and latency is solid, I use both windows file sharing (CIFS/SAMBA) and linux (NFS)Most importantly, I just had my second drive failure (RAID6). Buzzer was off. I keep it by my desk, and it just pops up a red light on the bad drive tray - so you don't need to figure out which drive is bad, that red light tells you exactly where the issue is. I login to the web interface, see SMART error, so simply popped out the drive (while it is running), replaced the bad drive with a good one, and put that tray back in -- all while the system was running. The system automatically detected the new drive and began rebuilding the array - impressive data preservation! Now, I haven't investigated to see if this drive was ACTUALLY that bad, but I can say it was up for about 3 years before this, so it's not a common issue, and it's best practice to be cautious with un-backed-up RAID arraysThese are all great, but I do want to mention one bad thing which has struck this and many other NAS devices - hacking. Hackers will encrypt all the files and require bitcoin $ to decrypt. Asustor was historically hacked as such. I don't run any services that expose the box to the internet, and my box worked just fine through it all. Just be very careful, though, if you intend to both store important data on these AND connect it to the internet, it would be hacking vulnerable.

I got this to help back up my Synology system after an energy spike damaged 2 drives. after rebuilding the drives, i was able to start the backup process. I was surprised on how easy it is to mount other non-Synology Nas drives. There are YouTube videos on how to do this. I have not tested the ethernet 10gb connections as I am limited at the moment to 1 and 2.5 connections. my home network is setup for only 1gb connections So far this system is running find. but i have noisy hard drives. i bought. mounting this system to the Synology. allowed me to triple my storage on my Synology

AS6706T:Very well designed hardware - only one nit, see below. The software (ADM) has a way to go, but for most tasks is good enough. At nearly the same price/capacity point, Synology is behind in H/W and a bit more costly, so I'm happy with ASUSTOR.The fan is quiet and the disk noise is not amplified by the mounts. Temperatures seem OK except a bit high during RAID synchronization (RAID5 in my case).The only H/W nit is the screws used to hold the case together are small and it's easy to spoil the head. Quite a bit of torque was needed to loosen them. Putting a lot of axial force was needed to avoid spoiling the (Phillips?) screw and I didn't do that initially. I'd like to find a source for exactly matching screws.You need to remove the case to add SSDs and RAM, so unless you're not going to do either take care to avoid spoiling the screw heads.

Although I am still in the middle of installing my Asustor Lockerstor 4 Gen3 AS6804T, the process has been straightforward so far. After installing the 2.0 TB SATA drives from my old HP (defunct) NAS, the Asustor informed me that two of the drives were faulty. After replacing them with new 2.0 TB drives, I now have a functional RAID 6 array. My final step is to set up user accounts and define how I want ongoing backups to be done. The built-in user interface is a novel (and quite useful) adjunct to the ASUSTOR Control Center PC application, which is easy to use and has very flexible options. Fit and finish are excellent. Over time, I'll also populate the four NVMe M.2 slots.

Totally blows away Qnap and presents a cleaner OS vs. Synology. The speed of this box is no joke.The OS is quite polished and so much better than than the so-called YT experts would have you believe.Thoroughly impressed and completely satisfied with this purchase.If WOL (Wake on Lan) is a critical function, avoid this unit. This functionality doesn't work.
