NAS newbie friendly

NAS newbie friendly
I recently purchased this system to make my own "cloud" and remove the need to save all our family photos on Amazon's prime subscription photo storage service. Prior to this I had never has a NAS and knew nothing about it. Once the system and Seagate Ironwolf NAS drive arrived, I put it all together, go it plugged in and within 20 minutes it was up and running. Synology has their own host of mobile apps that you can download for free that act in the same way Amazon's photo service does and automatically saves your photos to the NAS and even organizes them by date and time the picture was taken. I'm also able to store and share documents from the NAS much faster then trying to email everything or using a USB drive.Overall, I am very happy with the system and its compact design. It fit perfectly in a well ventilated cabinet next to my printer.

5.0 out of 5 stars 220J and 420J Very Fast, Easy Setup, Reliable and Quiet
Reviewed in the United States on April 4, 2020
Since Amazon groups the 220J and the 420J together I cannot review the 420j separately so I am revising my 220J review to include the 420J. I got the 420j 15 months after the 220j and as expected the 420j is also excellent. I actually got a great bargain on the 420j from the Amazon Warehouse for a returned items whose package indistinguishable from new.

I use the Synology 220J and 420j in a very simple way, to set it as the destination for the download of torrent files, backups, and for storing other large files I don't want to use up space on my solid-state drive. The PC is a Windows 10 and wired to a 1G LAN. Both NAS's are cabled directly to the 1G port of a Netgear r6700V3 router. AS long as I used wired (not wireless) the connection to both NAS is very fast even approaching the data limit of the 1G Ethernet interface. See the attached graph showing a speed test to both NASs from my laptop to each of the Synology units. Very fast indeed at the max capability of the 1Gb network.

THE GOOD:
-- EASY TO INSTALL: Doing very little more than installing the hard drives, letting the units run their initial installation, and then setting up a shared folder, and was quickly able to see the NAS's from both of my Windows 10 laptops. Very little to do to start using the NAS.
-- FAST TORRENT SAVES: Saving torrent files over an ethernet cabled connection the speed was as fast as the torrent downloads themselves. Very pleased.
-- GOOD STREAMING: I was able to play a 4K video from the 220J over the 1G LAN to an NVIDIA Shield with excellent results. No pausing or jerkiness. The 220j and the 1G LAN were not at all stressed by this.
-- GOOD SUPPORT: I was impressed with the tech support. They were always available and reasonably knowledgeable but were unable to offer a reason for the slow torrents.
-- QUIET: The fan in both units is surprisingly quiet and with adjustable speed.
-- FAST FILE TRANSFER: When I copy a file from the PC (where Ive saved a torrented file) to the file it's very fast. I see speeds of 115 MBps on a 1G LAN. See the attached speed test for both units.
-- VERY RELIABLE: Over 15 months of use the 220j NAS has been available 100% of the time, connecting to the network and operating over its web-based interface. I've had the 420j for only a week but I expect the same remarkable reliability from it.
-- CAREFUL WITH DRIVE SELECTION: I only say this because I initially installed some good value Hitachi 4TB drives that turned out to be noisy as heck. They made a loud thumping sound as the heads moved, so much so I had to change the location of the 220j to another room where I would not hear it.
-- QUIET HARD DRIVES: For the 420J I used 4ea Seagate Barracuda 4TB drives and I don't hear them at all. In fact, the fan is louder than any noise the drives make.

The Bad: Not a thing.

CONCLUSION: Both the 420j and the 220j do a lot of things and is probably much more sophisticated than I need and for the simple task of saving files from my PC over a LAN, but it's a great easy to setup and a supremely reliable solution.
