Synology DiskStation DS1621+ NAS Server with Ryzen 2.2GHz CPU, 4GB Memory, 6-Bay, 72TB Bundle with 6X 12TB Seagate IronWolf

Unit arrived well packaged and in pristine condition. software was easy to install. initial volume creation for an SHR LUN 4 x 8 TB IronWolf NAS drives took about 12.5 hours. Link aggregation across the 4 x 1 GigE ports was easy and well-documented. Added a 16 GB DIMM without issue. Added a pair of m.2 drives for cache. Added a dual port 10 GigE SFP+ Intel 520 adapter which was trouble free which was aggregated for a 20 Gbps link. It would be nice to have a 2nd one for them to replicate between. maybe someday.

So far this is a great NAS system; took very little time to set it up, configure it, get it on the network, and start using it. Ive had no issues with the product at this point. However, one of the reasons I chose this model and purchased extra memory was so that I could have quick and easy VMs when needed, but the VM capability requires an extra license that doesnt come with the unit.

Incredible performance! I upgraded from a DS413 and this is noticeably faster and I’ve got two more slots to work with. No regrets besides the initial cost. Expecting 8 years out of this one

Ive had this up and running for about a week and its been great easy setup and easy to use. Mainly use as a plex server and so far no issues.

Solid NAS. Much more responsive than my old DS218. I have 6 WD Pro 8Tb drives, 2 Samsung 500gb NVME m.2 drives as cache and 32 Gb of RAM.

This is my second Synology NAS, I upgraded to the 1620÷ from the 1515÷ and could not be happier.

Im the proud owner of a Synology DS410 which is finally feeling the pain of having no updates for a few years and it has survived 10 years now and still going strong (though slow in todays standards). This newer 1621+ is just incredible in speed and versatility where I used to have to build ESXi systems and connect them to the Synology for extra storage, now I can just host a few simple virtual machines on the Synology itself. The mounting brackets for the hard drives are included. Supports 2.5 and 3.5 drives. For 3.5 drives, it is a screw-less mounting design, which made it super easy. Also, comparing this with other NAS units out there, the ability to support mixed sized drives is also helpful when you can start smaller and then buy bigger and swap drives out as they becomes cheaper in price. Hoping for another 10 years out of this Synology.

I have a 15 year old 1511+ Synology NAS that is still going strong. From time to time I have to perform a hard reboot on it so I decided to purchase a new one. My 1511+ is encased in all metal but it looks like similar models are now plastic and not quite what they were more than a decade ago. After doing some research I ended up going with the 1621+ and I couldnt be happier. I was able to dump my noisy window server for a VM running on the nas. I only have one app that doesnt run well in Linux and needed this running somewhere. I simply RDP into it from my linux gaming rig and there is little to no lag or hesitation. It comes in an all metal case, and the AMD Ryzen CPU easily handles running my Valheim server in a docker! This model has very quiet fans which I believe are an upgrade from lower-end models. I was able to migrate my cameras and surveillance settings easily along with their respective licenses.

I replaced my QNAP 9-bay ARM based NAS to this, cuz I needed to run home assistant but the ARM HA rom never worked somehow. X86 home assistant works perfectly fine on this Synology unit, but other than that, there are few things that I am not very satisfied with. First, the USB transfer speed was really slow, it supposed be usb 3.1 port but when I try to transfer file from a usb 3.1 external hard drive, it took almost 6 days to transfer 3.5TB files into the nas. I have tried with different usb 3.1 cable, all front and rear ports on NAS, they all ended up with same speed, I don’t know why. Another thing that bothers me is, if I don’t use it for a little while, when I try to open the network mapped drive from my computer, the explorer will freezes for a few mins, feels like the NAS in sleep mode and restarted, but to be honest the response time is more than powering on the NAS from completely off, and I have set it not to sleep or hibernate, kinda confused me, these issues never happened on my QNAP. Other than these, it works just fine.

Amazon Reviewers-before I ordered this Synology unit I downloaded, read, and reviewed the “Synology 1621+ User Guide”. From a user perspective this document is essentially a technical and specifications explanation of the NAS. It was not very helpful to me for procedures to follow to correctly configure and set up this NAS. However, the “Amazon Reviewers” were outstanding! I read through all of their reviews and submitted my questions for those technical areas for which I needed information, but that was not included in the existing reviews. In every case, responses were made within 24 hours and answered my specific questions. This information permitted me to confirm my selection and to know that this NAS would meet my requirements before I placed my order. Synology Technology- since December 31st this NAS has performed perfectly. However, I needed additional assistance for the set up and configuration. I contacted Synology for assistance and could not have asked for better support. The technician for my support case has answered all of my questions. Inquiries submitted during the week are answered with 24 hours. The technician who is assisting me always provides comprehensive answers to my questions. He also includes technical publication extracts related to my question with Screen Prints and the device Path. Better solutions to my strategies are also provided. I wish that Synology had “Remote Connect” but that is not available. The technician suggested that I create a Word document with Screen Prints and upload that Word document from the Synology technical support website (portal). This has worked so far. I am adding six WD 10 TB Red NAS Pro HDDs and should complete my setup and configuration next week. Adding a HDD, one at a time requires about 10-15 hours to complete. At this juncture the 1621+ has performed perfectly and the NAS performance is outstanding!
