Synology4bay NAS RackStation RS820RP+ (Diskless), 4-bay; 2GB DDR4

Really good product and fast. However, you'll have to configure it (as with any NAS really) carefully if you want the speed and redundancy.How you configure it will determine performance but out of the box without added RAM and 4 x 6tb Seagate Iron Wolf hard drives in a RAID 10 configuration, this NAS is very responsive.The DSM software that comes with it is a joy to use and has loads of features to turn it into a mail server, vpn server, CRM server and a plethora of other features. It'll even backup your 365 account (it won't backup a business oneDrive account if it's associated with Sharepoint).Encryption is possible but shared, encrypted drives tend to dismount and need re-mounting unless you add a USB stick to act as a key manager.I've been installing and configuring Synology NAS devices for about 7 years now and this is a very smart option if huge storage isn't an issue.

RS1219+I ordered this as a cheap home NAS. Little did I know the rich feature set I was getting. I was originally going to get a netgear (which may be good -- I didn't get it so who can say) but I don't regret my choice here. I was concerned at first that this was only an 8-bay, but soon found that with 14TB drives this was more than enough for my home needs.Pros:- So many add-on packages. I've virtually replaced all my home servers and just run apps right off this.- Works well for Plex, Web Server, DNS, IScsi, etc in addition to the basic file-serving.Cons:- Very slow rebuild times when converting raid types (but isn't this true of all NAS systems). It took me 2 weeks to convert a 2-drive SHR to a 4-drive SHR2.- Only one PCIe slot for expansion*- Limited support on built-in packages**I just want to comment a bit on the cons:* This device provides four 1GB ports that can be bonded. This is great for my home needs. However, in order to add 10GB ports, I would need to add in an PCIe card that supports it. This can be done, but there is only 1 PCIe slot. This means if you want to use the M2.SSD cache you have to chose, as it also uses the PCIe slot. So you can have *either* M2 cache or 10GB ports, not both.** I had some problems with the built in packages and had to install some 3rd party packages. The DDNS for example has no support for easydns. Luckily, there is a 3rd party package for that. Also, some of the packages use outdated versions. For instance, you can set up apache 2.4 with PHP 7.3, but if you want to install for example MariaDB, it will force you to use an old PHP version. You can run them simultaneously, but it's a bit odd you can't just use the latest available. You can also shell to this system and install custom stuff - but that really defeats the purpose.Overall great system for the price though. If only the drives for it were as cheap.

DSM 7 makes setup a breeze; these RackStation units are now the backbone of all of my office file server deployments.

I purchased this server thinking it would be a reliable solution for backups. Fast forward 3 months later and it won't power on after the UPS battery died. Contacted support and it took several days to initiate an RMA request. After the RMA request was acknowledged, it took almost two weeks for the replacement server to get here. Once I received the replacement server, I was highly disappointed. The power button was missing and the case and lots of scratches and dings and the cover lid screws were almost stripped out. I put in my additional memory and 10 gbe cards and the device won't power up. I removed the upgraded RAM and network card and it's still won't power up. Replacement server is also crap. DON'T BUY THIS PRODUCT. Synology support is horrible.
