  • Software buggy. Tech/customer support completely non-responsive. RETURNED for refund.
Size: 4 Bay Color: AS67
Firstly, let's go through the GOOD. I purchased this unit because the hardware specifications were vastly superior to the same-priced unit from the competition (name starts with an S). Link aggregation was a piece of cake, and there are several link aggregation options to choose from even if your switch doesn't support it (mine does not). I was stoked about the 4 expansion slots for SSD's to be used as CACHE or STORAGE, and the upgradable RAM to 2 x 8GB for a max of 16GB RAM. Which I did. Setup was easy. Very easy. The information on the Asustor website - the "college" is very, very helpful and thorough. Documentation exists to learn about anything you could imagine regarding administration and use of the NAS. Applications are abundant, and usage was *mostly* pretty straightforward, if you're familiar with a NAS environment, concepts, file systems, permissions, and various forms of access and file transfer. Getting the drives installed was fairly straightforward. No instructions needed. The second RAM slot is easily accessible with only removing 3 screws and the case cover, as well as the 4 SSD expansion slots. Easy. That being said, here is the BAD: HARD DRIVE INSTALLATION Installing the drives is not toolless, so plan to bust out the old screwdriver, with 4 screws for each hard disk tray to get them mounted. MEMORY (RAM) INSTALLATION If you want to add one additional module of RAM to expand from the 4GB factory installed, it's 3 screws and the case is off, and you're adding that second piece easily. *BUT* if you want to swap out that factory 4GB module with something bigger, like I did, then you'd better grab a beer, about 30 minutes, some determination, and a container to hold all the tiny screws because you're going to remove about 7,623 screws and disassemble half of the NAS to get to that factory-installed 4GB RAM SODIMM. Okay, so I'm exaggerating *slightly* on the number of screws you'll remove to do that, but it's close. It was seriously ridiculous how far I had to dissassemble the NAS in order to access the factory-installed RAM. If you search online for instructions, you will find Asustor's own video showing how to do this and you'll fall asleep counting the number of screws they remove in the video. SSD CACHE After you have your RAID configured and things are humming along, and then you decide to install SSD's either as for Cache or additional Storage, you should know that if you ever need to EXPAND your RAID volume (i.e. swap out a drive for a larger one, or add a drive to an array) that you will need to REMOVE the SSD CACHE from the RAID Volume before you can expand it (add the new drive). The problem is, you CAN NOT REMOVE THE SSD CACHE. There is a button in the UI to do it, and it will show a nice little progress bar that goes to 100%, and then when you click OK, the SSD CACHE is still there, it is still 100% utilized, and it has not written the cache back to the Volume (hard disk drives). This is a bug in the software. As a result, you can't install / upgrade to a new hard disk without losing data. You WILL LOSE DATA if you expand the volume without removing the SSD cache first. BE WARNED! Asustor's own website tells you this. After troubleshooting this for a couple of days, I submitted a ticket. After no response from Asustor to my ticket in several days, I tried calling them which resulted in a recording and me leaving a message, which was never returned. Alas, I am unable to remove the SSD Cache to this day. A search of the ASUSTOR website (customer forums) will show you other customers are struggling with this issue as well and are frustrated. There are no responses in those forums from ASUSTOR employees either. UNRESPONSIVE NAS AFTER DATA TRANSFER Another major problem that I have encounted is that after setting up 4 x 500 GB SSD's in a CACHE to my 36TB RAID5 Volume, my NAS would become unresponsive after 500 GB of data was transferred to it. I was unable to see it on the network, unable to login to it remotely. Unable to list files on it, unable to do anything to it. The only option was to use the hardware LCD screen interface to manually reboot it, which worked most of the time to bring it back. I say "most of the time" because on a couple of occasions when this happened, even the LCD screen was off and although the NAS was still powered on, I could not see anything on the LCD despite pressing the up/down arrows on the unit and so I was forced to hard reset the unit (pull the power plug and wait 30 sec before powering up again). I believe I know why this was happening, if you care to read on. But know that I also submitted a ticket via ASUSTOR's website for support on this issue, and after I provided several more replies to myself with more and more information about the issue, I never received a SINGLE RESPONSE from them, even to this day. My SSD Cache was configured as read/write cache, which means that the NAS takes 2 of the SSD's and mirrors them for a read CACHE, which is 2 x 500 GB in essentially a low level RAID, resulting in 500GB of READ CACHE. The same happens for a WRITE CACHE. So even though I have 4 x 500GB SSD's, I have only 500GB of read cache, and 500GB of write cache. After attempting to rsync a multi terrabyte job copy to this NAS about 20 times and having my NAS become completely unresponsive EVERY SINGLE TIME after approximately 512 GB of data transfer, I have concluded that it was writing to the 500GB of write cache and then crashing. As a result, I've determined on my own that I needed to REMOVE THE SSD CACHE and then re-configure a new SSD cache as a READ CACHE only (no write cache). Then, when I'm copying more than 500GB of data to the NAS, it won't run out of cache and crash, because it will be writing to the hard disks instead of the SSD cache. THIS IS A THEORY, albeit a damn good one. The problem is, when I tried to remove the SSD CACHE, the NAS wouldn't do it, because of the bug, as I previously mentioned. CONCLUSION Alas, I really, REALLY wanted to like this NAS. And it's a good looking unit with sweet hardware. Asustor is doing the hardware part of this business correctly. Unfortunately, they're failing both in SOFTWARE and SUPPORT (non-existent), and therefore I CANNOT recommend this NAS whatsoever. Being able to remove an SSD cache is absolutely a BASIC REQUIREMENT because with any NAS you need the ability to remove drives and upgrade them to larger drives in the future. And if you can't do that, you might as well skip the NAS and just build yourself a RAID inside a cheap desktop. ... show more

  • The screws are TIGHT!!!
Size: 4 Bay Color: AS67
If you're intending to install NVME drives or install extra ram, and I highly recommend that you do, you'll have to unscrew small phillips screws on the back. The issue is that the screw design is not standard so a regular #1 doesn't exactly fit, and a smaller one doesn't exactly work either, and worse is that someone took the initiative to really smoke them down so they were very difficult to remove and because they're small, easy to strip. Initially I thought someone used red locktight because when it finally let go, it made a pretty loud *POP!* Heed this advice: Be careful that you have a really good screwdriver apex before buying. I was able to get it apart, but not without quite a lot of stark raving terror that I might strip it and ruin the NAS. From an operational standpoint the NAS is amazing. It does everything to the point that I figure it is the James Bond of NAS devices. Want a Minecraft server for your kids? Download Docker and the Minecraft server software and go. Want to run a Plex/Jellyfin? Rip all your DVD's and throw them on there to watch from wherever you are. Upgradability is fantastic. The only issues I had other than the above adventure with the backside screws is that installing the first stick of ram is stupidly easy. The second one? Ohhhh boy, you just about have to disassemble the entire NAS to get it in there. I understand that from a space/electronic standpoint sometimes it just isn't feasible, but come on. Engineers get paid the big bucks for a reason and you know that people are going to want to upgrade. The ASUSTor software and "College" Courses are actually extremely helpful. ... show more

  • Perfect replacement for my failed ASUS AS5002T NAS
Size: 2 Bay Color: AS67
I chose the ASUS AS6702T as a replacement for my failed ASUS AS5002T (seven years old). To my extreme pleasure, once I moved the old SSDs (maintaining the drive sled order) and powered on the unit, the new unit behaved exactly like the old one including the server identity! All of my files and settings were retained. The new unit got a new IP Address from my router, so I had to login to the MFP and edit the address book settings to use the new IP Address and, after testing, proved that both the SMB file share and FTP file share were populated from a scan. Concerned about the remaining lifespan of the SSDs (seven years old too), I bought and installed two 1 TB NVMe SSD sticks (Samsung 970 EVO Plus). I could find no way to migrate the volume from the old drives to the new ones and I tried every suggestion in the online tutorials plus some of my own. I submitted a query to ASUSTOR Tech Support and received a response the same day. After creating a new volume with the two new NVME drives and backing up the volume and exporting the settings, I powered off the unit, removed the drive sleds with the old SSDs, and then powered the unit back on. This forced a fresh system initialization process which, when finished, permitted me to import the system settings I has previously exported and copy the files from the export media. This was about a 90% recovery. I had to manually recreate the SMB file share, reconfigure the FTP service, and point the service to the correct folder. I had to alter the LED brightness to restore minimal visibility. I had to disable the power savings settings so that the NAS didn't go to sleep when not being accessed. Restoration complete! The network access speed increased to nearly equal that of a drive direct-attached to my PC! ... show more
