4.0 out of 5 stars Interesting unit, but some glitches out of the box
Reviewed in the United States on 13 October 2018
This is my third Asustor NAS unit. I also have an AS3102T (dual-core Intel) and AS3202T (quad core Intel) for comparison.

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.
