Delivery between Wed – Fri $9.99
Synology DS1621+ DiskStation 6 Bays 3.5"/2.5" SATA HDD/SSD AMD Ryzen V1500B, 4-Core 2.2GHz, 4 GB DDR4 ECC SODIMM, M2(2), 64-BIT, USB3.0(3), eSATA(2)

Absolutely love this NAS. I have upgraded from a DS916+ to this, and added and en extra 2 x 8TB HDD's to the other 4, the migration was seamless with no problems at all. Adding each HDD took 12 hours each so that shows the speed, on my DS916+ it took around 27 hours to add an 8TB HDD. I use it for streaming content in Plex and storing about 200,000 photos as well as files for my business. It has been installed a few months now and has given zero issues as we now expect from Synology products. I have installed a Samsung 16Gb stick of DDR4, which it should really have installed as default, 4Gb RAM is a bit bad on such a good unit.

Pros: compact and appears well built, DSM 7.0 interface is easy to useCons: Additional camera licenses are expensive. For RAM upgrades you need to use Synology branded RAM even though its not any different than that commercially available elsewhere but will cost you over twice the price.

Had some difficulty setting it up in Windows 10, took a few days and lots of searching, but in the end managed to get it to go, Setting up could be made much simpler with working examples and how to get past common recognition errors when setting up the Network to use Windows Explorer. Mapping the drives was most difficult to set up, seems it's a universal problem in Windows 10 for NAS devices. Sometimes its device dependent, several Laptops recognized the NAS instantly while desktops were much more difficult to set up. Overall data transfer is fast at around 100MB for my setup, but still learning how to use effectively. Not set up as RAID that's next. My setup is 2 off 2GB drives sufficient for now, but in hindsight should have purchased the 4 bay unit for later ... MoreHad some difficulty setting it up in Windows 10, took a few days and lots of searching, but in the end managed to get it to go, Setting up could be made much simpler with working examples and how to get past common recognition errors when setting up the Network to use Windows Explorer.

I have over 40 Synology NAS units installed in the field and this is one of 2 units I am disappointed in. The HDD and SSDs MUST be SYNOLOGY they are not compatible with any other drives. Before purchasing this unit make sure you are getting the right HDD/SDDs or you will be disappointed. B&H was great with swapping the drives for compatible ones.
I've been a Synology fan for many years so I didn't hesitate to upgrade to the DS3622xs+ and throw 12 Seagate IronWolf Pro drives in it to keep my photos safe. After all, it has some pretty great specs including 10GbE. But to my surprise, the NAS complained that the drives were "unverified" and needed to be replaced. While I was able to create a RAID 10 volume, the volume was in a permanent "critical" state and refused to use SMART data. I tested pulling a drive to see if it would automatically rebuild using a hot spare, and it didn't seem to work either. Upon further research, I learned that Synology has changed their NASes starting with this model to only support their own Synology branded hard drives, which apparently are rebadged Toshiba drives. There's a lot of ... MoreI've been a Synology fan for many years so I didn't hesitate to upgrade to the DS3622xs+ and throw 12 Seagate IronWolf Pro drives in it to keep my photos safe.

Upon further research, I learned that Synology has changed their NASes starting with this model to only support their own Synology branded hard drives, which apparently are rebadged Toshiba drives. There's a lot of outrage online about this.This vendor lock-in, which I didn't know prior to purchasing it, was just gutting to hear about. It adds substantial overall cost to the NAS and makes this model not worth it. I'm really sad that my decade-long love for Synology came to an end this way.
I bought it as replacement of a DS1515+ which collapsed after 4 and a half years of continuous service.Afraid about migration (once after reinstalling the DSM operation system I discovered not all settings are stored in the backup), it went really smooth. Obviously the DSM OS stored in the disks didn't match the new hardware and didn't started at power on, but identifying it with the web browser it requested to download and install the correct DSM according to the hardware, taking care to use the same version already existing in the disks, and using the option for system migration before starting installation, then just restart and that's all, system came alive as if nothing would happen, just with new more powerful body.Very happy with the migration experience.
Pros: Easy to useSoftware is user friendlyLarge capacity it can handleCons: Noise (while processing and sometimes when it is idle) Mobile apps to access photo / data struggles to connect sometime. Once connected everything is smooth
Pros: - Impressive Lineup of Software- Really easy to configure RAID and System- You can use it for Backup- You can Play Music, Photos and Videos on Cast-Compartible Devices like Google HomeCons: - You need to consider if you need it
How unfortunate. We as the consumers are locked into using their own HDDs otherwise our GUI starts shouting at us that the HDDs are unverified. Why not just offer an extended warranty if using Synology HDDS? I can't believe they lowered themselves to this level.
Switched from QNAP TS-451 due to Intel LPC bus degradation infamous problem. Comparing to QNAP I find it very quiet and responsive. Bought Kingston memory https://www.digitec.ch/en/s1/product/kingston-so-ddr4-pc-2666-cl19-server-premier-ecc-1-x-16gb-ddr4-2666-so-dimm-memory-15887457?supplier=406802Works ok, just find annoying receiving warning from NAS that this memory module is not whitelisted.
