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

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

Flexibility, 6 bays, setup fairly easy. I’m using 6 4tb drives giving close to 18tb avg. I’m using it on a win 10 network with 4 total NAS units. Speed and function were exactly as I expected. I store photos and data files all critical. I expect long service from the unit, drives will be changed around the 2-4 yr service life on a 24/7 cycle.

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.

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.

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!

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

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

Everything works great. Love the Ryzen processor. I do recommend you get the memory upgrades. I got the 16GB, and the software seems to use excess RAM as disk cache so that is nice. I am so happy with it, I think I will go ahead and upgrade to 10Gb and NVME caches as well.

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 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.
