  • Excellent NAS drive, good performance, large app library
Style: 2-bay; 2GB DDR4 Size: DS220+
I needed to replace my aging WD NAS, which was struggling to keep up with my needs. After quite a bit of research and product comparisons, I decided to go with the market leader, and bought a NAS that seemed likely to be able to support my needs for several years, and offered some options for expanding the ways I use a NAS. For context, I mainly use my NAS as "network-attached storage": I back up files, and I share files for use on our multiple home computers. I don't use it for remote access (security concern: I'd rather use cloud storage services for that), and I don't use it as a repository for a media server, or anything else like that. I decided to use WD "Red" drives for this unit: based on specs and user and professional reviews, they seemed most likely to run reliably for as long as I needed. My previous experience with WD black, blue, and red drives has been consistently positive, whereas other vendors have let me down. Installation and setup was very easy: I had the unit up and running within a few minutes. Copying files over from my old NAS took some time, but the performance of this Synology unit exceeded my expectations. I was also pleased with how much faster my backup jobs were. I was especially pleased when apps that use network files began running much faster: so clearly both read and write performance were much improved in comparion with the old system. I also set up a USB backup. It took a little bit of reading in the Synology KB to learn how to do it right, but after that it was a breeze. I plugged in a USB hard drive in the back port (the front port can be configured for use with the USB Copy button), opened up the Hyper Backup app, and ran the initial backup to copy the entire NAS contents to the USB drive. Then I scheduled it to run incremental jobs every day, so now my paranoid backup demon is happy. (I save backup drives in a secure location to provide "disaster recovery"; overkill perhaps, but it buys peace of mind.) One criticism: the unit came with only 2GB memory, which seems cheesy. And what makes is super-cheesy is the way they price their branded "compatible memory" at ridiculous multiples of the market price. I was able to buy a 4GB Samsung memory card for under $15, and it worked just fine. You can do a web search and see that others have upgraded using larger memory cards. The Synology KB website is very good: it's well written and comprehensive. There's also an active user community, so there is a ton of information easily available. Overall I'm very happy with my Synology purchase, and would buy their NAS products again without hesitation. ... show more

  • Versatile Media Server and Home Data Storage Solution
Style: 2-bay; 2GB DDR4 Size: DS224+
I purchased the Synology DS224+ NAS primarily as a media server. My requirements were pretty straightforward. I was in the process of transferring and consolidating years of analog and digital multimedia. I was not comfortable with sticking with cloud storage. Unpredictable internet speed demanded local storage for performance. So, I decided to get a networked storage device that was fast and simple to set up and maintain. After considerable research, I settled on Synology's DS224+. I had some experience using Plex on my PC with an external drive, so the built-in Plex Server app was a bonus. The setup of the RAID 1 (other options are available) dual drive (drives purchased separately) was straightforward using the Linux-based DSM 7 operating system. My knowledge of networking is limited, so it took some poking around to figure out how to map a shared folder on the NAS to a lettered drive on my PC. Transferring all of the media files from my PC to the NAS was quick once the setup was complete. Performance using LAN Plex clients on my PC, Android tablet, Roku and phone was better than I expected. I decided to take it one step further and set up remote access. Things get a little more challenging with remote access. Synology's QuickConnect setup is, again, straightforward. But it is not quite as secure as a VPN connection and with QuickConnect, you can't access other devices on the LAN remotely. The DSM 7 NAS OS has options for VPN service. So, I decided to set up the OpenVPN server for remote access. This is where things get sticky. Without getting into all of the details, the default VPN configuration makes some minor security compromises, perhaps to accommodate older client configurations. I had to make some tweaks to the configuration and regenerate the security certificate key to get a sold VPN connection with no warnings. So, you may want to have someone handy who knows a bit about VPN setup to help out, or be prepared to do some research! The Plex performance was so good that I decided to ditch my Tablo and purchase an HDHomeRun quad tuner as an add-on to the Plex server. That was super easy to set up. Now, I have an Over The Air DVR setup that integrates with all of my other media. So far, I have found the Plex performance and reliability to be far superior to the Tablo, especially when accessing it remotely. If you are simply looking for a simple home NAS and media server setup, the Synology DS224+ provides a solid solution at a reasonable price. Add on a multi-channel network tuner and you end up with a setup that will seriously tempt you into cutting the cord on cable and paid streaming services. If you are willing to fiddle around with the setup a bit, you get the added functionality of a secure VPN connection into the NAS and Media Server as well as other devices on your home LAN. Bottom line: The Synology DS224+ is solid winner in the entry level NAS arena. ... show more
