TERRAMASTER F4-212 4 Bay NAS - Quad Core CPU, 2GB DDR4 RAM, Network Attached Storage Personal Cloud with Rich Backup Solutions (Diskless)

This has given a good performance

Much of the hate for this NAS is not supported. Well.....maybe some of it is. SIMPLIFICATION TIME: The F4-212 is a solid working, reliable (for the time I have owned it) and predictable NAS, TOS 5.x is workable, provides plenty of options, flexibility and information. The only major flaw is shipping the NAS with a 1gbe port. I plugged a generic Realtek USB3 2.5gbe adapter in, configured & rebooted and my thruput jumped from 115MB\s to 220MB\s, a substantial jump and more than adequate to handle moderate duty storage needs. ETA: I bumped the review up to 5 stars. Why? I'm now into week 3 using this. I have not discovered any major flaws and I much prefer using it to my Thecus N5550, a costly device in the day, 2.5X the F4 price. I had a need to do some major juggling of drives, NAS units and files and I had the easiest time of all of that using the F4. There are more than a few people who think the F4-212 is junk. Ok, it's mainly plastic with a steel skeleton. Nothing wrong with that. Tool less drive mounting (only for 3.5" hdd). Again, nothing wrong with that. I had all 4 drives inserted and ready to go in 5 minutes. I have not yet swamped the CPU nor RAM even running 2 parallel rsync feeds to it and hitting 220MBs thruput. I grant the F4 feels cheap compared to my ancient Thecus and Zyxel NASes. All lighweight plastic screams disposable. Heck, my Maiwo hardware 4 bay RAID unit (1/2 the F4 price) is made like a tank. @ $200 for the F4 is half the price of the next 4 bay NAS and will likely handle 80% of what that more expensive NAS can do. MAKE certain you download the newest client package from TerraMaster. I had some unpleasant issues with older versions. New releases just work. I haven't the courage to install TOS 6-7 beta. I will wait for others to try it and write it up on Reddit.

This product is an absolute piece of junk. Do not buy this product unless you like to throw your money down the toilet. Does not take any HDs. I bought WD HDs - still nothing. Tried multiple HDs with no joy. Not even worth one star - i'd give it less than 1 if I could.

After about a month to transfer only 6TB to it, it is unusable. Never saw a NAS that slow. Can't access the data, can't access the web interface. This is ridiculous. I was previously using a USB disk connected to OpenMediaVault and will go back to it as it was WAY faster. By the time I was ready to test it when the data was transfered to it, it was too late to ask for a refund. Total Rip off.

It is not a simple 'Plug & Play' system, like my old Dlink one. It took a while to sort it all out, but working great. Did a full reset and wasn't accessing with address or Windows, had to start with the IP address, then it went through the Downloader. Working very well, would recommend for basic home NAS.

I was hoping for better just with storage and no apps running TNAS always alerted it was slow/sluggish. After a reboot can no longer get in via GUI or desktop/mobile app. I am able to access my files from my computer to get off to remove my drives and return product. Not worth the money even with a discount.
