Asustor Lockerstor 4 Gen3 AS6804T, 4 Bay NAS Network Storage, AMD Ryzen Quad-Core 2.3 GHz, 16GB RAM ECC DDR5, 4 M.2 NVMe Slots, Dual 5GbE & Dual 10GbE Port, USB 4.0 Type-C, Network Attached Storage

Having worked with several different Networked and NAS devices over the years, both at home and work, I decided to replace my very old home Buffalo NAS. After reading a few reviews on home NAS's, it came down to what I wanted to do with it, in terms of hardware, software and upgradability. As the usual suspects, Synology and Qnap where also in the running, however, I went for another NAS I haven't used before, the Asustor Lockerstor 4 AS6604T.This is really a business NAS, rather than a home NAS, but it ticked all the right boxes for me, cheaper that Synolgy or Qnap for roughly the same specs. I installed 8GB ram in the AS6604T, rather than the standard 4GB, it also accepts a large selection of differrent compatible drives, has Dual M.2 NVMe SSD ports for fast caching, more specially 2.5 GbE ports with up to 5 Gbps under Link Aggregation, since my home computer came with a 2.5 Gbps port, this is a nice bonus for me.The Asustore software is available through it's App Central and has a load of applications, although it's still not quiet as polished as the Synology or Qnap applications, it is, however, catching up fast.For newbies using the NAS for the first time, you can install the OS and setup the NAS by running the default easy installer, it'll do all the install work for you, for the experienced user who wants control, you can manually install the OS.I install 4 x 4TB Seagate Ironwolf NAS hard drives, you'll need a screw-driver to install these, but it shouldn't be a problem, install went smoothly, and is set at RAID 5.I've had the system running for a few days now, no errors to report and I'm very happy with it, I'm glad I got this NAS, it is doing everything I needed it to do for a good price. Time to retire the old home Buffalo NAS.Yashi

i have owned many nas setups and as i will no longer buy wd i had to look for new systems, i have to say this asustor nas seems to be very good, low noise, easy setup, lots of apps and runs my home backup systems and emby really well.would highly recommend

I've had this NAS since the 6th of April 2023.This is a limited review, using this NAS as a Plex Server.So, buying from Amazon was fine, and delivery was fine, the NAS had no hard drives in it, so no worries about the package being delivered.I had a Western Digital PR4100 before and I loved it....I bought this NAS for two reasons, 1. I had run out of storage, 2. This NAS will hardware transcode 4K HDR to 1080P, which my lovey Western Digital NAS could not do :(Let's talk about money, so Amazon had the best price... however, this was a BIG investment, we are talking over £600, so it needs to work and be good... and that is without hard drives!!!!!!!I was concerned at first about the ADM? operating system, having watched loads of videos on youtube, with many suggesting it's less refined then what you get with Qnap, or Synology, however, it's fine, in fact, it was easy to use, don't forget, I'm reviewing this as a Plex server, so I'm not experienced all the other NAS stuff.I installed 4 Ironwolf 4TB NAS drives, you have to use a screwdriver, and put very tiny screws in.... crumbs, it was a bit tricky at first, the screws are small, take your time and make sure you don't cross thread them...So it done a ADM operating system update when turned on... and started to build the volume... I'm using Raid 5....Is it a good Plex Server???? Yes, it's does do 4K HDR hardware transcoding, but only to 1080p, but you will not get anything else then that from any other manufacturer, that is what the chips do right now.It's is fast, so starting a video, and skipping forward is fine...The 4 drives seem a bit noisy, I will be moving it to a cabinet, so it should be okay, but if you wanted it in a living room, and not in a cabinet, it does make some noise...Do I like.... I do... it works just fine, I hated the ADM software at first, but I have now learned where everything is, and it's fine, in fact it's great.

This is definately one of the best NAS devices that I have ever purchased and used. It is extremely fast, the software (ADM) is excellent, fluid and responsive. Setting up the RAID 5 array with 4 6TB drives and 2 128GB M.2 SSDs for Caching was very quick, and without incident.Very very happy with this, and would strongly recommend this to anyone looking for a NAS. I've seen and sadly used some of the "cheaper" (the term is relative since no real NAS is actually cheap!) devices from other vendors and had nothing but problems, from the NAS being extremely slow, to being totally unresponsive; to being told that creating a RAID 5 array on 4 6TB drives will take a ridiculous time (> 1week).ASUSTOR is a trusted brand when it comes to NAS devices and given that it was formed by both ASUS and ADATA, I think its fair to say that they know a thing or two about data storage.The remote access feature (EZ Connect) requires UPNP on your router (which is a bad idea), and so I instead used port forwarding on my router and have been able to access this without any problems.Again, very highly recommended.

Very well made and great to use.

The necessity to remove the 4xSSD adapter (and lose all SSD caching capability) in order to use a 10Gb adapter knocks it down one star.Significantly faster and more versatile than the WD PR4100 its replaced. Plex streaming is significantly smoother and the CPU is a lot more capable.Removing/upgrading the second RAM slot is very fiddly. Easy access is blocked by the internal structure's diagonal, instead of being an easily accessible rectangular hole. 16GB works no problems.All in, I probably should've waited for the QNAP TS-464, for the best of both worlds.
