Have used a Zyxel NAS-540 for the last 7 years, my main purpose for it is iTunes library containment and sharing and backup of my PCs. Had a couple HDD failures and decided 7 years was too long for any computer component - and found the Terramaster F4-423 on Amazon through searching for NAS products. The all-aluminum case attracted me to this product as well as the dual fans. Came quickly and well packaged - I also ordered 4x Samsung 1TB SSDs from Amazon via Terramaster’s helpful compatibility list (time to join the 21st century and retire the old HDD spindles!). Very glad I made this purchase - really everything was quite easy for an “advanced novice” to handle. Only challenge on installation was fitting the 2.5” SSDs to the included carriers (the included screws work fine, just a little kludgey at first). The downloadable PC desktop app works like a charm and found my new Terramaster immediately which enabled me to initialize everything with just a few clicks. I put my 4x SSDs in old school RAID-5, but Terramaster includes some nifty advanced data protection algorithms which would be really helpful for having disks of different sizes for sure. Overall it didn’t take too much effort to move data over and start to use the new NAS - I was able to listen to tunes via Sonos within 2 hours of unboxing. There are many many features on the desktop app, most of which I likely won’t use but could see it being helpful for business users like remote access and iSCSI target just for instance. The NIC teaming feature worked amazingly well for a non-CCNA - I told the app what I wanted to do and it offered some options and away it went. Just a well thought out and put together OS, app, and overall design. Nice they included cushioned “feet” for the desk surface as well - small touches that really complete the job.

Only wishes: slicker drive carriers that maybe don’t require a screwdriver (again, file under “wouldn’t that be nice!”) and a data migration tool from existing storage would be amazing for those with more rudimentary Windows/networking skills. It may very well have one I just don’t know it’s called - there again are a lot of features.

Would highly recommend this to anyone in the market for a well priced, well engineered, and nice looking small NAS!

I purchased this Network Attached Storage dual drive on on March 29, 2019 .

The unit came in a very substantial box with pre-cut foam inserts to protect the unit during shipping.

The unit was sealed in a plastic bag. Included was a smaller box with the power supply, 2 different sets of screws for mounting hard drives. The chrome screws for 3.5" drives and the black screws for 2.5" drives like SSD which apparently take a slightly differrent screw thread. Also included was a nice screwdriver and a Ethernet cable. Setting up the drive was easy. I just followed the instructions that came with it which said to download the TNAS-PC program from their web site to aid in the setup.

I initially started out with just 1 4TB Seagate Ironwolf RED NAS hard drive in it configured as a "Single" HDD which worked fine.

A week later I ordered a 2nd identical 4TB Seagate Ironwolf RED NAS hard drive. When it arrived I installed it into the 2nd available HDD slot.

The unit recognized the new drive. I was able to go into the control panel and re-configure the NAS to be a RAID 1 mirror image configuration. This keeps an identical copy of all the data from the 1st drive on the 2nd hard drive to provide some additional security from lost files.

I have had other NAS storage devices on my network but they were not stable or reliable. This unit is always there and is very intuitive on how to change things using the control panel. It has a variable speed fan that is super quiet.

Many applications are available to download onto the unit. Like PLEX for serving music and video media for one.

I also use this drive to record my security cameras when they detect motion. The FTP server feature that comes with this NAS is perfect for this.

I created a user account for the cameras to use and created a "shared folder" for the videos to be stored on.

I have each camera storing to their own folder so it is easy to locate the videos.

Setting up the FTP function in the camera was a little bit trickier but with a support call I got through it.

I am very pleased with this unit. It is a great value for the money and feel it is worth a 5 star rating.

The F2-423 NAS has so far performed solidly for me. After getting past the initial learning curve for the user interface, it was straightforward to create users, groups, shared folders, etc.

One of my requirements when shopping for a NAS was disk encryption. Although full-disk encryption is not supported, encryption of shared folders is. One important note is the encryption keys are not cached in the hardware, which means whenever the NAS is rebooted, each encrypted shared folder must be manually mounted, and the encryption key must be entered manually. This is actually a good thing, because if the device is stolen, the data will be inaccessible.

When creating an encrypted shared folder, there is a prompt to enter the encryption key. The UI lists several special characters that are not allowed. However, when attempting to create a key with the "@" and ":" characters (which are not on the "not allowed" list), the folder creation returned an "operation failed" message without explaining why it failed. After scratching my head for a while, it finally occurred to me to remove the special characters, and the shared folders were created successfully.

A couple of other quirks around the Security Advisor:

- "Security isolation mode" is reported as not enabled when it is.

- "Firewall": Security Advisor recommends to create firewall rules. It seemed odd to me that Terramaster did not provide default firewall rules and relied on their customers to create them. There do appear to be default firewall rules included in the TOS 6.0 beta, although Security Advisor still complains that no firewall rules are set.

In all fairness, none of the quirks should be considered non-starters when deciding whether to purchase this product. It is a very solid, cost-effective storage solution for personal or small business use.

I have an old Iomega NAS that was end of life in 2015 but still worked fine. It started to periodically lock up so I decided it was time for a replacement. I researched and read reviews, researched some more and decided on the TerraMaster F4-423. This was due to several factors including it just looks better than most. More importantly it had the specs I was looking for as well as very good upgradability. I loaded it with 4 - 4TB Seagate IronWolf drives and a WD 500GB SSD for caching. Unboxing and the unit and the aluminum housing looks as good as I thought. The instructions for set-up are online and easy to follow. The drives are super easy to install. If there is anything to knock off a star for ease of use, it's the installation of the SSD and add'l memory. There's nothing in the instructions and I had to find a YouTube video to see how to do it. The housing must be removed (6 screws) to access the motherboard. I've taken apart countless electronics so it was simple enough, but a novice might find this a little daunting.

Once I added the SSD, replaced the cover I started it up. It is very quiet. There is some initialization, didn't take long. Creating my volume (RAID 5) was simple. It took a bit of time to initialize (expected), but in the end I have 10.88TB of storage. I want to mention another cool feature, TerraMaster's TRAID. You can use drives of various sizes and created multiple raids to use all of the space. On different NASes you'd create your RAID based on the smallest drive and the rest of the space would just be lost. If you're geeky, check it out.

Once the NAS was fully operational I started to create new users and folders, which is done through the TOS online interface. It took a little bit of hunting to find certain things but reviews say the new interface is FAR better then the old. It was time to move some data. My wife's stuff was the test just in case anything got lost. Mapped her a drive and she copied about 300GB from the old NAS to the new. The thing I was impressed with is the efficient use of space on the new NAS. One of her folders on the old device was 43gb of data which was using 61GB of drive space. On the new NAS it's 43gb of data using 44gb of drive space.

Obviously I won't know for some time if this NAS lasts as long as my old one. But from what I've seen so far, it is well worth what I spent. I've seen a lot more expensive devices that don't give you what the TerraMaster does.

Edit: Don't forget when you're going through the setup to go to the last page and follow the instructions for getting a free 4GB stick of RAM. Once I sent my email I had the RAM in 3 days.

I am so done with terramaster. DO NOT BUY, ONLY WORKS WITH TERRAMASTER RAM AT 5 TIME THE COST.

They only sell their ram as single sticks. Terramaster is selling a single stick of 16gig ram for $100 when every other company (who mostly make higher quality ram) for between $30-$50 PER SET. It's not even ECC, this unit only uses None-ECC ram. This is nothing but plain greed, price gauging. This units only saving grace is, it is easy to install other OSs on it. Unfortunately the other OS's like true nas it not really newby friendly. If you change the OS you can use any hardware. Magically any quality brand RAM will work.

Their price for their rams is nothing but out right greed and price gauging. Terramaster wants $200 for a mediocre 32 gig set of ram. Let that sink in.

It works but is extremely finicky.

Everything seems to be working fine. Except I kept getting errors during data transfer. I've been trying to transfer around 10t of data from my old drives to the new one in the NAS. I reached out to Tech support and they advised me on some trouble shooting ideas. To isolate the issue I started testing things one at a time. Starting with The HHD. I used the utility within the Terramaster OS and a standalone program called Scan Disk Info. They both came back as the HHD is fine. Now everything seems to be running fine. I transferred 2t overnight while sleeping without errors. Both the TM and scan disk info are only diagnostic they don't fix anything all they do is report issues. I don't know why running them and getting a clean report fixed the issue but here we are. I guess it coincidentally got better at the same time I ran the diagnostics. I don't know why it got better and would like to find out. At the same time I am willing to except things as they are and move to other projects.

I am so done with terramaster. DO NOT BUY, ONLY WORKS WITH TERRAMASTER RAM AT 5* THE COST

Upon receipt I immediately installed TrueNAS. I wanted a stable, mature environment, and TrueNAS Scale was it. Fortunately, TerraMaster makes this very, very easy to do. What's more, they make it super simple to jump back if you ever change your mind. I'll post instructions at the end of my review because there is are a lot of confusing and contradictory tutorials out there.

First, the hardware build quality is excellent. The case is solid aluminum and has a hefty feel to it. At idle, the fans are very quiet and do a good job at moving air -- more on that below. The drive LEDs are bright enough to be seen in daylight, but not bright enough to be obnoxious in the dark. I love that TerraMaster bucked the trend of using ultra-bright blue LEDs and went for a more subtle approach.

CPU performance exceeded my expectations for a value-priced NAS like this. The N5095 is no gaming platform but it is more than ample horsepower for typical NAS tasks. I'm currently running scripts to back up all my cloud platforms into the NAS, send an encrypted backup of my NAS to B2, and run a few other tasks. The system is responsive and happily takes whatever I throw at it.

The drive cages are well built and feel like they'll stand up to an acceptable amount of use. I wouldn't call them as sturdy as something you'd see on an actual server, but they're better than you'd expect for home use. That said if you plan on swapping drives around on a daily basis, I recommend looking for something more enterprise-grade.

The internal components are packed in tight. The good news is that you'll never need to access this unit's internals if all you ever do is swap drives around. If you ever want to upgrade RAM or install M.2 drives, you'll basically lay the unit down on its face (on a towel), remove a few screws, remove the fan panel, disconnect the fans, and then slide the sides / top / bottom off as one piece. This isn't difficult at all, and again, most people will never need to do this. Despite being jammed in there, system temperatures remained reasonable thanks to good airflow and heat management design. Under extreme load my CPU got up to 79C. At idle it's closer to 40C.

You will hear some drive noise, and how much depends on what drives you use. I'm using four Seagate Ironwolf 8 TB drives and I occasionally hear a small amount of access noise. It's only noticeable in a quiet environment; if I have music on in the background or we're watching TV, I don't hear it. Still, if you're planning on using this in a recording studio or somewhere where noise is absolutely unacceptable, you'll want to place this elsewhere. The drive mounts caught me by surprise, but if you simply follow TerraMaster's instructions, 3.5" SATA drives are easy to install.

One of the great features about this NAS is how easy it is to install your own operating system. There are many NAS OSes to choose from including TrueNAS, UnRAID, and OpenMediaVault, along with conventional x86 operating systems like Debian or Ubuntu. I went with TrueNAS. Below are the steps I used to get everything up and running:

First: Back up any important data; this process will wipe out all data on the NAS. Also make sure you review the installation instructions for TrueNAS or whatever OS you install.

1) Download the TrueNAS (or UnRAID, or whatever) installer image and flash it to a USB drive.

2) Carefully open the TerraMaster by removing the aluminum panels.

3) Locate and remove a small USB flash drive on the motherboard. It may be hidden by a grey ribbon cable. This is the TerraMaster TOS installation media. You should set this aside somewhere safe in case you decide you ever want to revert to TOS.

4) Reassemble the NAS. Do not turn it back on yet.

5) Connect the NAS to a monitor and keyboard using the HDMI and USB ports.

6) Plug in your TrueNAS installer USB. Contrary to what you may see elsewhere, you do not need to stick this USB drive into same motherboard slot that held the TOS installation media. Any USB port will work.

7) Turn on the TerraMaster. Repeatedly tap the Del key to enter BIOS.

8) Select your USB boot media and go. If installing UnRAID, you may want to adjust your boot settings to always boot from USB.

9) Follow the installation procedure for TrueNAS (or UnRAID, or whatever).

10) When installation is finished, remove the TrueNAS installation media, connect the ethernet cable, and reboot.

11) Follow TrueNAS' post-install instructions.

Congratulations! You now have a very competent NAS. If you ever want to revert back to TerraMaster's TOS:

1) This process will wipe the NAS, so back up all your important data.

2) Shut down the NAS.

3) Plug the TerraMaster TOS USB into any available USB slot

4) Turn on the NAS.

Congratulations! You're back on TerraMaster's TOS.

One final word of advice: if you plug it in and just get continuous beeping, your memory or your M.2 is not seated correctly. Power down, disassemble, and re-check everything you tinkered with.

I bought the 2 bay f243 to replace an aged and failing NAS from another manufacturer. I installed Seagate NAS drives 2 x 4tb each and the install was SUPER easy. You pop the drive bay, pop the side holders off and pop in the drive, reverse process. Fired it up following their directions and within 15 minutes I was pushing files to it and getting people back onto it.

Build of the unit is metal, fit and finish is great. Connectivity works well as I have both 2.5s going to a 2.5 switch and it is moving data very fast. If you read the startup guide there is a free offer in it, do not pass it up. I have yet to decide if I will add an NVME or not. So far, have not seen a need as I am pushing 100gb user data onto it in record time about the hardest it will get hit in my application.

Interface is more or less a Linux desktop, running TOS and takes just a few seconds to get good with it. Changed each network connection to a static one was fairly easy.

Only issue I can see if you have poor internet connection, the device downloads its OS in startup, you may want to download it and do it manually if you have limited or poor connectivity, otherwise was a breeze and where it sits I am using a Verizon Internet device (aka a 5g cell device) and it worked fine.

I recently purchased the Terra Master F2-223 NAS device, and I must say, I am very happy with it's performance, functionality, and affordability. After installing 2 10tb NAS drives (with tool less ease).

I began setting up the Terra master F2-223 which was easy enough, interface was user-friendly. I'd say in about 20 minutes I was ready to start filling my drives.

The Terra Master F2-223 utilizes the TOS (Terramaster Operating System), which was pretty user-friendly . TOS provides all the NAS management tools, along with a bunch optional app installations (Plex, Emby, Jellyfish) to name a few.

The Terra Master F2-223 is an excellent choice for individuals looking for an affordable and reliable network-attached storage solution. I was building a simple media server. The unit drives cool and quiet.

As a newbie to things NAS, my onboarding experience has been great overall. Assembling the hardware was a breeze. Next, was setting up the operating system (TOS 4.31) which was as handled by a very user-friendly Installation wizard.

The single let down for me was not finding any information for my specific situation. My primary access to the world wide web is through my mobile phone along with a chromebook, plus a Linux laptop for more complex tasks. As Terramaster used Linux for their operating system TOS, it's not really unreasonable to expect that there would be instructions relevant to Linux users, isn't it? Well, I wasted quite a bit of time looking for how to set up TOS using a Linux machine only to find everything is about Windows and Macs !!!

I had to use my imagination to get the job done. How? I saw from the guide that access to TOS was via the local IP address and I thought I would try using the same (I fired up my router admin page and looked up the TNAS IP address) on my browser to see what happens. Voila! that got me to the Installation Wizard!!! I didn't even need the apps that Terramaster was asking Windows and Mac users to download!

Terramaster would really score positive points if they included this information in their support page as well as their guides.

While the Nas device good. They delivered the wrong and old model. I ordered F4-423 was they purposely delivered the old model f4-223.

Superb Product.
