How many 4tb disks does tr-004-44r-us include?

None. It's the RAID controller and enclosure only. you buy the disks separately in the size of your choosing. I recommend that you use one of the following models: WD Red, WD Gold , WD Purple, Seagate Ironwolf, or Seagate Skyhawk. These drives are made for use in RAID arrays, and will give you far fewer issues with the array loosing sync and having to rebuild. I'm using WD Red drives in a RAID 5 configuration in mine and love them. I've had the array up and running for almost a year and have never had any problems at all. Make sure to use 4 drives of the same size, make, and model for best performance and reliability.

Is it possible to password protect this device?

Not native to the device. It is just an external USB drive array. It can be managed from a QNAP NAS and you can password protect data from within the app, but you cannot password protect the actual drive itself.

I can leave this turn on 24/7 like any other nas like synology units? note: i know this is a das not a nas

I don't have this model, but yes to your answer. You can leave it on 24/7/365 if you want. whatever you have it connected to will control it and put it in sleep mode when not in use.

1. Can I plug this into my pc to expand its storage? 2. Can I use this with a c to usb adapter as my pc does not have a c slot

1. Yes. You might/probably need to download their management software 2. Don't need an adapter because the PC connection is via a common USB type A plug. The "C" end plugs into the device. It's kind of short though.

Easy to use RAID enclosure USB C for backup

Stable USB C RAID box that works well, stable, decent speed backups, fan is a bit noisy, all drives attach without screws and doors can be locked. Dip switches to change RAID options. Thumbs up.

Waste of time and money

I bought this hoping it would be a nice and easy introduction to NAS...Seemed simple enough: Set up the NAS, slap a few drives in, start copying over files and share it with everyone in my network. What a joke. Media Server apps don't start or run correctly, attempting to listen to audio files stored on the NAS leads to several choppy pauses in the tracks, and even opening something as simple as a .pdf or a .doc can lead to substantial lag and pauses ending in a blank half-page before an "I/O Error" window pops in your face. I wanted this to take the sizable audio, video, and book library OFF of my desktop and put it in a more convenient to access centralized storage, but it would have been simpler to just build a second, barebones junk PC and put the drives in there. No special software would be needed, no user credentials asked for when attempting to access a shared folder, no lag spikes. Until they step up their customer service game and/or significantly improve their NAS performance, don't bother.

Connected devices suffer a considerable performance hit

I noticed that both the TR-004 and TR-002 slow my computer down considerably and my computer boots up really slow if they are attached. If These devices are attached to a routers USB ports the router randomly hard crashes as well.

Good So Far

So far so good, but I wish the unit allowed 4 drives in RAID-1, not just 2 drives at a time in RAID-1. Kind disappointed about that. Maybe shame on me for not researching more, but since this company does provide custom controller software...
