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

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.

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

This is my second Synology NAS and the price/features/quality/support is awesome. Running 6x Synology 8TB NAS drives, 2x 2TB Crucial P5 NVMe and 2x 16GB Arch Memory SO-DIMMs. No complaints! Migration from my old Synology NAS couldnt be easier. Originally started with 4x drives in SHR-1 config and added two more drives and converted the storage pool to SHR-2 and expanded the volume. Took a long time (nearly a month), but couldnt been easier to do. Use the NAS for TimeMachine backups, file storage, app server (mostly via docker containers) and more. Easy cloud backups to Wasabi which is inexpensive.

If you can stomach the up-front cost, buy a Synology. The convenience and ease of use are well worth the price. You could build a more powerful NAS yourself for less money, but it would use more power, take up more space, and (most importantly) require more time/hassle to manage. My previous setup was a Mac mini with some USB attached storage. That worked mostly great for about 9 years, and I was looking to update the setup and thought Id give some proper NAS options a look. I have always been put off by the relatively high prices of NAS devices, particularly Synology ones, but after reading about all the built-in features I took the plunge and gave the Synology DS1621+ a try. Im glad I did! This device has a fantastic array of features, most of which I dont really need, but the ones that I use work very well and (just as importantly) were extremely simple to set up. Here are some thoughts on the things Im using so far: Synology Hybrid Raid (SHR): Im using SHR-2 for double redundancy and it was painless to set up. I love that I can pop in another drive later on and expand the pool without any trouble. It also supports checksum validation and correction with the Data Scrubbing feature if youre using the default BTRFS file system, so Ive set that to run monthly to avoid bit-rot. I dont have enough experience with this yet to say how it works in practice, but in principle this is great. Shared folders: this is the bread and butter for a NAS, and it was extremely easy to setup and configure with Synology DSM. It works SO much better than the shared drives on my old Mac mini because it handles permissions properly and everything just works. Time machine backup: this is essentially an extension of the shared folders, with one extra configuration required to make the folder appear as a native network time machine backup destination. Worked seamlessly for configuring backups for a few Macs. Docker containers: I migrated all my docker containers which were previously running on Docker Desktop on the Mac mini to the Synology and they work much better than they did on the Mac. They are faster running and simple to manage with a decent built-in UI. Id have preferred built-in Docker Compose support, hopefully thatll come in the future, but for my use case configuring via the UI was OK. Application portal / reverse proxy: I love this feature, it makes routing requests to various services super easy. Im comfortable configuring nginx by hand or via automation, but for home use I prefer a simple UI like Synology provides. You can assign certificates to routes, and everything works great with my custom domain. Certificates: I has high hopes for the built-in Lets Encrypt support, but unfortunately it requires the server to be exposed to the internet (no thanks). Hopefully in the future they support the DNS challenge option, but for now the easy way to solve this is to use the open source acme.sh which has support for tons of DNS providers and has built-in hooks to register certificates with Synologys UI. I have acme.sh running with Synologys Task Scheduler and it works great. VPN Server: supports L2TP/IPSec so you can use the built-in VPN for iPhone / Mac, no third party apps required on your devices. This is the only thing I have exposed to the internet, and in my testing it has worked right out of the box with very minimal configuration needed. Other thoughts: - Synology Chat: Slack knockoff, works better than I expected honestly! I disabled this because I dont fully trust the security of this app for exposing it to the internet. - Hyper Backup: havent fully configured this yet, but seems to support a good selection of services - File Station: really nice web-based file browser which you can access via the admin UI, or as a standalone web UI There are so many more features that I havent even begun to explore, like the built-in Plex support, but I can say so far this NAS has exceeded my expectations and I expect that Ill keep finding new useful features as I keep digging and configuring. On the hardware front, I did a couple upgrades: - 32GB ram: https://smile.amazon.com/gp/product/B0899KV2L5/ - Synology 10Gbps ethernet adapter: https://smile.amazon.com/gp/product/B07G9N9KJT/ Im using two Seagate IronWolf 8TB drives and two WD Red Plus 8TB drives so far and both work well. The Seagate drives have some extra diagnostic information available due to a special built-in integration with IronWolf drives that is very neat. Unfortunately the WD Red Plus drives say they are unverified because Synology hasnt added them to the official list of verified drives for the DS1621+, but I bet that was an oversight because the WD Red Plus drives are listed as officially verified with pretty much every other Synology NAS. Doesnt make any difference in practice. Despite the high all-in cost, Im completely satisfied with my purchase and expect that itll last me a long time.

I introduced myself to Synology back in 2015 when I purchased my first NAS, the DS1515+. Prior to this I used compaq servers over the years to provide reliable NW file storage. I like the Synology product as DSM is quite feature rich. I have an extensive background in NW and FS technologies so for me DSM was a nice fit with a minimal learning curve. Synology does a nice job at marrying HW, NOS and feature rich applications that dont require a-lot of tweaking to get running and fine-tune. Since then added the DX717 expansion and I am currently running 30TB of HD storage using both BTRFS and EXT4 FS. I was having some issues on the DS1515+ with BTRFS FS. I was unable to resolve issues with CHECKSUM errors corrupting files. After 6 years the DS1515+ chassis also would fail to power on at times after scheduled maintenance shutdowns. So, I decided it was time to replace the main unit and I did so with the DS1621+. All issues resolved at this time and BTRFS is rock solid. I like the snapshot abilities of this FS and its advantages over EXT4. I installed 2ea seagate NVMEs in a read/write cache utilizing RAID1 and the speed of my websites are breathtaking! Overall I am quite pleased with the DS1621+. I was expecting more out of the RYZEN CPU in respect to transcoding with PLEX and the reason I took 1-star off my overall review of this product. I did see quite the improvement in Surveillance station when scrubbing security videos on this platform. I run 10 HD cams running 1080P at 30FPS and this unit does so with minimum effort. This box defiantly outperforms the DS1515+ by far and the disk transfer rates are in par with the documented specifications. Hopefully Ill get another 6+ plus years of good use out of this product. I am running DSM 7 and I really like the changes and features in this version of DSM. The built in NVME slots provided me with 2 additional slots I can now populate with mechanical HDs for additional FS storage.BTW I recently upgraded my Apple TV HD devices with the Apple TV 4K units and transcoding demands on PLEX have dropped significantly. So at this time PLEX is able to stream all of my multimedia through out my NW seamlessly and reliably. Love it!

Have had this for 10 months now, I did max out the ram to 32GB, all bays populated with WD Red Pro drives, along with a DX517 also populated with WD Red Pro drives. The system drives are in an SHR2 array, and the DX517 in a second SHR2 array. Im also using an SSD cache drive (iirc, Samsung EVO drive). Transfer between the system drives and the external are at about 120MiB. Im also getting about the same transfer speed over my gigabit network connection. As to the review comment on USB speeds... You are probably better off adding 10GB Ethernet, though if youre using spinning drives, it wont really matter as USB is faster than what youre going to get out of the drives. Ive setup Plex server for the first time, which was relatively pain free, although the service does seem to have a bug where Plex will hang and need to be restarted on occassion... am considering a crontab to automate this check/restart. I have also enabled SSH. The Application Portal for reverse proxy is a really nice addition, though Im now using a dedicated Raspberry pi for wireguard, pihole and reverse proxy since Docker on this device is a pain, more so without docker-compose. All in all, a night and day difference from my old NAS. That said, many of the applications Ive tried to run arent worth running on this device. If you consider anything beyond file storage a bonus, youll be very happy.

I always built my own storage servers over the years but decided to try the pre-built NAS route this time. Processor - This has a Ryzen SOC that houses the first generation Ryzen 4 cores and 8 threads. It seems fairly powerful. RAM - Comes with ECC memory - since I dont like bit rot in my files I always used ECC RAM and I dont recall any models under $1,000 ever being sold that would take ECC. I upgraded to two 16GB ECC Arch Memory modules I also purchased from Amazon and I do not receive any warnings about having unsupported memory. I wanted the system to have dual channel memory and I figured I would buy two 16GB RAM to feed the caches. 4GB is probably fine in a most cases. M.2 - I have two 1TB NVMe modules from different manufactures using them as a cache in RAID1 - In DSM 7 you can also pin BTRFS metadata to the cache and speed it up even more, cannot wait for this feature! HDD - Easy to install lots of reporting on health etc. I shuck WD drives to use in the system and I convert them to 4Kn drives before using. I use BTRFS with RAID-5 for both RAID and data protection. SSD - I have a couple SATA SSDs in it and they work fine except for trim. Check compatibly because it will not use the trim command on some SSDs that support it. I back up to an external USB drive but Ill probably buy a second NAS and insert my left over 4GB ECC RAM module in it and do a NAS to NAS backup. Works great with my Unifi UDMPRO router setting up UPNP based port rules through the DSM web interface.

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

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!

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. The RAM I bought is available here: https://www.amazon.com/gp/product/B07YXCBVWX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
