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

Gonna keep this short. I got the Synology 6 bay NAS DiskStation DS1621+. Great unit. Does everything I wanted except video/plex steaming. (Itll do it, but not well) If youre looking for a streaming box, get an Intel Xeon unit. Intel will have hardware to let you view those 4K encoded videos. But I kitted out mine. Max RAM, Max SSD Cache, and Max HDD. Its more than I need, but Its been super reliable for me. Even in power outages (your milage may vary. I do recommend at least a 2.5 or 10GbE card if you need extra bandwidth. Be sure your computers MoBo supports it if you plan to directly connect it. In short, if you dont need a video connection or video streaming, this is a great option.

I was worried that the NAS work be underpowered. Worried for nothing. Works great. The built in software makes all the difference!

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 2nd Synology product (the first one is a ds1517+) and Im loving it! Im able to migrate some services I set up on the first nas over to the 2nd so eventually, I can reset my first one so I will be able to optimize it better than I initially did. The DS 1621+ has the speed I need and is upgradeable if I decide I need to install a 10gb network card or nvme cache to speed things up even more! Ive been using it for about 2 weeks now and so far its handling everything Ive thrown at it! I would happily suggest someone consider this if they need a nas with 6 bays and fast storage. If you plan on hosting your own media server because this model doesnt have onboard video in the processor I would avoid trying to run something like plex directly on it but instead set the plex server upon an old desktop or laptop or on another nas that has a processor with onboard/external graphics built-in so it can handle the transcoding portion while the nas handles the data storage portion of your home videos

Works perfectly with x520 SFP+ Network card. Fast and stable NAS.

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

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.

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.

This has been much faster and just as solid of a user experience as my previous Synology nas. I like that it has the faster processor and 6 bays. I have moved my two other nas units to backup roles, this is a worthy upgrade.

This review is for the Synology DS1621+ Ive just finished getting my new 1621+ fully installed and up to speed. It took about three weeks to install all the software packages and figure all the settings out and though Im still thinking through some of the decisions Ive made, Im ready to write a review. I bought the DS1621+ to augment a QNAP TS-453-Be I purchased just under a year ago as a replacement for a QNAP TS-453 Pro which had its motherboard die. This is my second Synology--my first was a two-bay model which was my first NAS. I use my server for the following: 1) Plex server. Music only. And for this purpose the Synology is great. 2) Photo organization. I use Synologys photo organization software and Lightroom. I like running duplicate software because if one goes on the fritz, I can turn to the other. Synologys Moments AI photo organization software is good. Perhaps a bit less capable than QNAPs QuMagie, but close and Synology wont ever be far behind on software. 3) Backups of Windows and Mac computers through Acronis and Time Machine. 4) Virtual machine Windows 10 for when I need to get to something and Im not at my own computer. And for running the disk indexer X1 to have all my documents immediately accessible wherever I am. I never thought I would return to Synology after gettting a QNAP, but here I am with the 1621+, and I find myself preferring my Synology 1621+ to my QNAP TS-453-Be for a number of reasons. But first, let me say that on the hardware front, QNAP probably wins. Its close, but QNAP seems to give you more hardware for the price. For instance you can get 2.5GB ethernet, Intel chip, VMM-capable four-bay NAS from QNAP for less than the price of this 1621+ which is stuck at 1GB (unless you buy a PCIE card). Of course, the QNAP would be a four-bay model to the Synologys six bays, but the QNAP would have an HDMI port, more USB ports, an audio jack, and on and on. Hardware is QNAPs strength. The reasons for buying Synology: First, Synology has a better three-year warranty to QNAPs newly-revised-downward two years. And my first QNAP died a bad death last spring right after the five year mark (prompting my purchase of the TS-453-BE) while my original two-bay Synology still runs today, eleven years after I purchased it. In the end, I will take reliability over features, and I consider Synology more reliable. The second reason I went with this Synology is the constant problems with security QNAP servers have had over the last several years. Its hard to fault QNAP for being attacked, and theyve probably hardened their security--perhaps even beyond Synologys--as a result, but Ive left my QNAP unplugged for much of the last year because of the constant attacks their servers have faced. But the ultimate reason to get Synology is the software. Synology software is just a cut above everyone else, including QNAP. It feels bulletproof. Most important for me was the Synology disk system which treats all your hard drives--and they can be of varied sizes--as one large storage pool across the entirety of which RAID striping can occur. With QNAP, if you want to increase the amount of storage you have in your NAS, you must back up the NAS, replace all your hard drives, do a restore and go on with your newly increased capacity. You cant replace just one drive with a larger drive. You are limited to addressing in all drives just the amount of storage available in the smallest drive. Thus, if you have one 4TB drive and three 12TB drives in your QNAP NAS, maximum RAID storage would be 12TB, not 40 TB, because only 4TB of each drive could be used for RAID. Synology allows the use of drives of whatever size you wish, placing them all together into one large pool, all of which can be used for RAID striping. So in the above scenario, Synology would have 40TB available in RAID format for your use. This is a huge Synology advantage. I could say much more about Synologys excellent software, but Ill finish by recommending that you buy more RAM if you want to run virtual machines off the 1621+. I added a 16GB ECC RAM module for a total installed RAM of 20TB. I allocated 10GB of RAM to a virtual machine running Windows 10 and its fairly snappy. I bought ECC RAM here on Amazon which cost half the price of Synology RAM, and it works fine without any reporting of non-standard RAM.
