Es wird vieles Voraus gesetzt, man muss wissen was ist EZ-Connect, Link Aggregation, SMB, NFS, Shared Folders, ACL etc.

Für den Privatanwender unüberschaubar....

The new AS4002T, a dual-core, non-Intel unit with a new Marvell ARM Cortex processor at 1.6 GHz. It also has 2 GB of 2400 MHz DDR4 RAM and three LAN ports - two Gigabit ports and a third, 10 Gigabit port.
Asustor nicely includes not one but THREE ethernet cables in the box - two Cat 5e cables and one Cat 6e. I have never seen any manufacturer put three ethernet cables in the box before - most give you just one, even if they have dual ports.
There area few benefits to the 4002T unit over the 3000-series versions:
1. A more rigid case design
2. The 4002 has a removable, magnetic front panel that covers user-accessible drive bays that are hot swappable (you have to remove the cover for the 300-series units and the drives are screwed in and are not hot-swappable)
3. The 4002's drive bays are tool-less; the drives are secured by plastic drive rails that snap along the sides of the drive caddies very similar to what QNAP does in the TS 128/228 series. No screws.
4. The 4002 has two Gb ethernet ports and one 10 Gb port. All three can be combined in various combinations for link aggregation in Asustor's operating system.
Interestingly, the new V2 version of the lower-level AS3102T now has dual ethernet ports, but there is as of yet no V2 version of the higher-end AS3202T, so you're stuck with the single Gb port on that one.
There are several negatives to the 4002 relative to the 3000-series NASes:
1. The 4002 is more expensive than either the 3102 or 3202, yet has an inferior processor (but faster memory).
2. The 4002 takes significantly longer to boot up/restart
3. the 4002 runs hotter than the quad-core Intel 3202 and much hotter than the Intel dual-core 3102.
4. I have had to reset the AS4002T several times due to issues - more on that below, none of which I have seen at all in either my AS3102T or AS3202T.
When I first my 4002 up, I tried using the Cat 6e cable using the 10 Gb port. Asustor's Control Center utility immediately found the new NAS and I was able to start setup, but it hung at the "system volume" phase at 11% and would not move from there. I closed and reopened my browser, tried to reinitialize, and it stopped there. I then disconnected from the 10 Gb port and used the two 1 Gb ports instead, and initialization completed very quickly with no issues. I thought the 10 Gb port would work even if connected to a Gb network, but it wouldn't.
I initially installed two 4 TB WD Red drives. I had checked both drives before this issue in a dock on my Windows computer and they showed healthy with no issues. Within a couple hours, I started getting "system failure" messages and the second HD light on the case was blinking amber while the first HD was green. I ran Dr Asustor and it aid my second hard drive was unstable. I went into the Smart data and it showed Current Pending Sector errors. I tested this drive in my dock with SeaTools and it now shows failing. I pulled the drive and replaced it with the only other 4TB drive I had available, a healthy WD blue drive. Was fine for a day and same issue cropped up - again only drive 2. This one, however, shows the RAID1 status as "good" with the SMART status as "Bad". The Red drive I used earlier showed a compromised RAID and degraded status. I just pulled it, tested it in my dock, and it, too, shows failing. Interestingly, both failed drives show the same SMART errors.
The Red drive in bay 1 has been fine the whole time.
Strange that two previously perfectly good drives failed after being put into bay 2 in this NAS within a day or so. Can't say it's the NAS but seems strangely coincidental.
I ordered and just got two Seagate Constellations, which I will try and I'll reinitialize the NAS with them installed. Fortunately they were pretty cheap so not out a lot of money if something happens. I have Seagate desktop drives in my 3202 and WD Reds in my 3102 and no issues in either one after many months.
Constellations are in and the system is up and running with no issues so far. Will update later if things change.

I installed two 4TB WD Red drives that are mirrored. Installation was easy: the front panel is held on magnetically, drive bays are released using a lever, and drives are mounted with a snap-in plastic rails. Installation of the two drives took about five minutes.
I used the downloadable software to install from a Windows machine. It worked smoothly and setup took just a few minutes, and it was ready and available once the drives initialized. There is also a mobile app that can be used to discover, set up, and manage the device; I have only used it to check status. The browser console served by the device is pretty good - simple enough for a casual user, but a more technical user can set up a lot of things, such as which connections to allow or block or set up a syslog client.
I appreciate that the mobile app is not the only means to set up the system; IME experience, mobile-only interfaces often make setup and management more difficult. For Linux users, I suspect you may need to use the mobile app to configure. When I turned on the NAS, I could see it on the network through my Bitdefender Box, but it did not have an IP address. I did not tinker with other ways to access the management console, because I had a ready way to configure the device.
So far, the NAS has been running for 10 days with no issues. That's obviously not enough time to make any prediction about long-term performance, but it's doing its job so far.

I was a little concerned that bugs that serious were missed and put into a live environment where they could potentially cause data loss.
Fast forward to a few weeks ago; the NAS suddenly stopped working. I tried rebooting, resetting, pulling the drive, but could not get it to boot up. I created a support ticket listing what I had done (on October 4th) and someone responded the next day with the standard; "Have you tried turning it off and on again?" I replied with the information they requested and after three days had not heard anything back so I messaged them again. Five days after I messaged them again, I received a reply saying that the device hardware had failed and that I would have to call the US Hotline 1-909-465-5688 so they can arrange for a repair. (They did mention that they had some time off to celebrate the Moon festival but I'm pretty sure my ticket sat a few day while people were working)
I called the number but was immediately redirected to voicemail. There was no message or information about who I was calling, just redirected to an unknown voicemail account. I left a message in hopes that someone would respond but have little hope of that happening.
Bottom line is I like the device. It has a lot of apps, and it's fairly easy to use. The problem is, it's a very import piece of equipment that I use for backing up client photos/video for photography work and I don't feel like I can fully trust it. Especially when I can't get quick customer service when an issue arises.
