Amazing product
This is an excellent product that delivers fast and reliable performance. I had previously been using a Buffalo NAS, but once the company discontinued its service, the associated software stopped functioning on my iPhone. After switching to this solution, I have been very impressed with its stability, ease of use, and overall value. It is a worthwhile investment for anyone seeking a dependable NAS system.

Powerful NAS
After watching loads of reviews on YouTube mainly compare NAS I decided on this Asustor model , it bucks the trend of the other two ‘giants’ Synology and Ugreen but the form and tech specs of this model is far more superior in my mind, I’ve made good use of the ability to add SSD s having purchased two 4TB drives separately I also upgraded the memory to 16gb which boosts the performance I have some fun spinning up my own VMs and have successfully set up media drivers of Plex and jellyfin. Overall a brilliant machine I would recommend

Easy to set up and run
Great example of setup and forget gear. I had mine running in a few minutes and adding a media server was a doddle. It is responsive, quiet and so far very reliable. The way these devices should be.

Easy to set up and get working
Buying a NAS in general is not a cheap experience (especially when adding the disks), so I knew what I was getting into. What I will say is that Asustor made it really easy to set up and get it working. Disk installation was easy. Installing th M.2 storage needed a little dismantling, but was easy enough. Once the hardware was sorted, it was time to install the Software. Software installation was so easy, I was up and running in no time. The amount and types of apps available is pretty good. Overall a good ànd easy experience and the NAS is working well.

Easy To Set Up And Use
I've found the Asustor NAS really easy to set up and use. I have it configured with a 2tb NVME SSD as the OS and Volume 1 drive and two 4tb IronWolf drives in Raid 1 as Volume 2. The set up guide walks you through getting the drives ready and in the Raid version most applicable to you. If you want the OS on the SSD (recommended to make it snappy) then just install the SSD and no drives and go through the initial setup then add the HDDs later. I'm using it as a cold file store, hot file store for video editing and as a Jellyfin media server, but there's much more it can do.

First impressions are very compact NAS
First impressions are this a compact NAS. The provision of a demo video online is extremely helpful in setting up this ASUSTOR AS5402T along with the comprehensive Knowledge Base. My previous NAS was a QNAP TS-253A which is now 5 years old and certainly not as easy to setup. I use them both for Home Surveillance purposes. Well worth it and certainly recommend this unit.

Toolless M.2 drive clip broken
This is a stupid oversight as on paper, the unit should be good, but why oh why does a NAS need 'toolless' installation for its M.2 drives, when you have to use a screwdriver to remove the top cover of the unit anyway? You already have a screwdriver, so what's the problem with fitting the drive with the screw (that all retail M.2 units come with anyway)? Why is using (clearly) unsuitable plastic clips preferred? As soon as I opened the unit I found that one of the clips had been snapped off. I like to think ASUStor didn't ship it like this, so I can only assume someone previously returned a unit after the clip snapped and it got sent back out without being checked. Probably just as well as I can return and avoid issues in future.

Very Glitchy - Does Not Inspire Confidence
Update: June 2024: I've had no more file issues with the system so far and have managed to resolve the transcoding now using a combination of settings, but it seemed that the hardware transcoding options had defaulted back to defaults, so was not being utilised. So I've increased my rating up by 2 more stars. One other thing to watch out for is the HDD enclosures. These are very flimsy plastic and you always get the feeling you are going to snap them both in pulling them out and replacing them. I have just inserted 4 drives and I have to say the first time the enclosure with the HDD in did not slide in perfectly, so was 1mm out of alignment. I had to make 3 attempts to try and line this up again (not easy unless you are looking at it at eye level) before the enclosure engaged. Note to Asustor - come on guys, these are not cheap units and you could of spent a little more on a more robust enclosure system. Did I mention that the other flimsy part are the screwless plastic securing tabs that hold the HDDs into the enclosure: what a nightmare trying to get these off and on - again, the feeling they are going to break off at the slightest pressure is not very reassuring. Having done a lot of research before purchase, I took a chance on Asustor based on Hardware comparisons with Synology and QNAP. I have to say their instructions for disassembly to upgrade the memory and insert the M.2 modules using the so called user manual is terrible. The images bear no resemblance to how you get the cover off and it's near on impossible without using force. Next the setup - well that was relatively easy to do, but already I'm having major issues with ADM. I've lost my temper 3 days on the trot now and wasted countless hours of my life because of ADM software glitches. The File explorer is horrendous as it does not update files. I've wasted an afternoon today looking for missing files that are not showing up in the attached USB drive using the built in File Explorer in ADM. I thought the files were missing - a complete folder of converted video files just gone missing! Three times I thought I'd copied these over and still nothing - refreshed and nothing. So I checked the history of the conversion programme to get the path and this showed they had been moved to the NAS where they should be under the USB drive - but again nothing there! I finally restarted the NAS and unplugged the USB, plugged it in again and this time after refreshing the File Manager, the folders along with the missing folders and files magically appeared! This does not bode well for the future to be honest and I am very disappointed of what I've had to go through to get these back. I've lost all confidence in this unit and am deciding whether to return it back. These things are not cheap to buy and you expect the bloody software to work properly and not give you heart failure all the time when you think your data is missing. I also had some issues with Hardware transcoding using Jellyfin, but the lack of clear documentation as to the settings is a poor feature (the Jellyfin user manual is written for people with PhDs) and not with the home user / small office user in mind. I had to reset everything and switch settings on one by one to get it to work and stop buffering of videos. There are features that I want to explore at a later date like moving my Hyper V VM over, but am not too sure now given the 'disappearing data' issue. This is all without any HDDs installed so far - I only have 2 x 2TB SSDs installed with the ADM OS and the media I have so far copied over. I will be adding HDDs later on as needed for a second RAID volume. But I haven't 'moved' any critical data over yet until I'm satisfied it is going to be safe there and only after I have another backup outside of the NAS. I will update my review going forward.

Awesome server, it's perfect. I use this as a DLNA server for music. I had previously used the Windows 11 media streaming, which was awful. The Asustor is much better, and works as it should with my HEOS app (Windows did not). The option to use SSDs is great, totally silent operation, and fast. I used an external SSD to migrate my music library on the the drives. At one point it must have had a power outage and lost all the data. I got help from tech support; they guided me to get another drive and upgrade to RAID1 mirroring, which should prevent that from happening again. Tech support was very informative and helpful.

I was looking for a replacement home server for storing data and streaming media, with the ability to access that data remotely. My most recent solution was a big bulky and power-hungry HP Z840 which taught be a lot about Windows Server 2022 but everything was a challenge to implement - especially remote access since Microsoft dumped the Essentials server line (why??). I own a QNAP NAS for backing up said server, and found a lot of what it did unintuitive and hard to integrate with Windows. I had always respected ASUS products, so turned to this beauty to see if it could continue the tradition. Boy could it ever, with a tenth the power draw and minimal setup! Streaming is in fact BETTER compared to my dual-Xeon 64GB RAM beast. Plus it can be set up as a hub for a home security camera solution (but I haven't gotten there yet so cannot advise). If you're in the market for such a solution, I cannot recommend this product enough. Just one warning: Don't set up NIC pairing ... that appears to be buggy and caused a lot of hard-to-troubleshoot network communication errors.

Getting motivated/excited to upgrade your NAS is difficult; your old one seems "good enough" so why bother? This thing is worth the bother! It has the power and expandablity to be a real workhorse. It runs Docker like a champ! It has enough processing power to run Plex with real-time transcoding. Optional SSDs serve as read/write caches to speed things up. I have the NAS in a closet and under heavy access, you can hear the drives, but the NAS itself is very quiet. It rarely needs a reboot and has been rock solid for me.
