QNAPTS-464-8G-48WD-US 4 Bay High-Performance Desktop NAS with 24TB Storage Capacity, Preconfigured RAID 5 WD Red Plus HDD Bundle

While the official site says that memory in TS-664-8G-US is not upgradable, this model arrived with one of the two memory slots populated with 8GB stick and a QC sticker over it. I plugged another 8GB stick into the free slot and it happily accepted that. Shows 16GB total now.This is an excellent NAS for money. I have both M.2 NVME slots populated as well as QNAP PCIe card with 2 x 2TB M.2 SATA drives. That is besides the 6 HD drives in the usual slots. Plenty of disk space.Do not expect this to be a powerful container or VM host, although 16GB of memory should get you part way there. But it is a great storage device. That is exactly what I needed. It runs quietly. In fact, I am using WD 5400 rpm drives to make it as quiet as possible. That is enough speed for a multimedia center and a host for backups.

To note I've been using home NAS solutions since back in 2002. My 1st NAS (still running) was a Netgear Readynas (4 2TB drives = 6TB RAID5). This was the only NAS that had ever failed me (about 5 years old (I lost a controller card and was unable to salvage my RAID 5). I needed more space and purchased a Synology around 2006 (4 4TB drives for 12TB RAID5). These 2 were enough until around 2020 when I bought a TerraMaster (apparently the new price leader 5 8GB drives for a 32TB RAID5) and my 1st NAS that supported Plex.I've been expanding my digital media library rapidly due to getting a high end entertainment system supporting DTX pro, Dolby True HD, basically all lossless content. This had me maxing out all 3 of my NAS's and I finally decided to get a 4th this year (2024). My primary use is to run a PLEX server with over 1000 movies, 5000 TV shows and growing fast.I attempted to get another Terramaster (to note for same specs as QNAP the Terramaster was $140 less) . I apparently got a bad one and after over a week of trying to set it up I ended up with a brick (restoring factory defaults destroyed it somehow. Having had some issues with my 2020 terramaster, and now with a DOA, I decided to check out the competition.The main options were a 5 bay Synology, 6 bay Asustor, and this QNAP. The QNAP was the 2nd best price and I really wanted to have a 6 bay as I had already purchased 6 14 TB drives. My experience with QNAP has been stellar so far. It has much better app compatibility than Terramaster. The hardware I'm running (6 14 TB drives for 70TB RAID5, 1 TB M.2 SSD for caching, 16TB memory, and a quad core processor make this by far the most powerful NAS I've ever had (which can be seen in the very fast speeds I've observed since)I was able to get this NAS built (added 6 drives, created RAID5, synched the drive, added M2 SSD (1TB) setup for caching, added 8 GB memory to max out that as well. The impressive part is I had all this done in just over 24 hours from the N AS arriving at my house. I have also been able to setup an rsync that will allow me to migrate the data from my 2020 Terramaster (which I plan on using for backups). I will be setting up my new switch (2.5TB) and running the 4 NASs on that going forward with a total of 120TB. I'm hoping this will be my last upgrade for a while.I definitely recommend this product, although my NAS needs are basically pretty simple and all the info needed to get up and running was very easy to find online in a couple youtube videos or guides. The user interface is fairly intuitive and performance like I said is much better than anything I've worked on to date. The TerraMaster does offer a bit higher specs for 20% less, and I'm assuming I just got as bad one, but I do think this QNAP is much better than my current 2020 Terramaster and the one I tried to setup a couple weeks ago.

I added x4 10TBs WD HDDs and used this for my Plex server. Its running 24x7 and I have other remote users connecting with no issues. Other than the noise from the disks vibrating the plastic plate covering, there are no issues. Great value for the money and power consumption is not high.

Why did you pick this product vs others?:This system is fantastic out of the box. Very easy setup to do the basics and works as expected. NAS is probably a misnomer because it seems capable of a heck of a lot more.

Updated:Contrary to the specs my new TS-464 has two RAM slots, one of which is populated with an 8GB DDR4-3200 SO-DIMM. It recognizes up to 32GB although Intel ARK specifies 16GB max. I was also able to update the NIC with a generic Intel-based X710-DA2 10Gb SFP+. The PCIe slot cover is flat (see QNAP's photos) and does not fit with a regular LP bracket, so I had to create one myself.______________________________________________________________________________________The TS-464 is a decent little NAS suitable for home users. If you are familiar with other QNAPs it uses the same software (firmware) and will run either QuTS or the QuTS Hero. The latter is desirable for the ZFS high integrity file system, which is unusual in this class. It was easy to update the FW from QuTS to the latest QuTS Hero. I populated it with WD drives on the compatibility list, but it should work with most drives. The CPU is the Celeron N5095. The NAS is about as compact and lightweight as is practical for a 4-bay NAS and even includes a low profile PCIe 3.0 x2 slot. There are 7 LEDs to show status of the NAS.There are a few caveats that are related to the low cost and market segment of the x64 series.1. Power is via a bulky 12v/7.5A power brick rather than having an AC cord and built in power supply.2. The front panel blocks airflow. When it is removed the drives under writes are about 5 degrees C cooler than when in place at auto fan speeds. It might be necessary to turn up the fan a little.3. The current US model is claimed to be the -8G-US, which contains 8GB non-upgradable RAM. The hardware info shows 8/0GB but I have not taken it apart to see if there is another slot. RAM size is especially important to ARC in ZFS so I'd prefer 16GB.

Honestly it’s way better than what I’ve seen Synology have, both from hardware and software perspective
