Synology DS1821+ External HDD/SSD Reviews
Symbology is the best
My best friend told me to buy Synology since my drop balls crashed and I’m so glad I did because it’s very excellent hardware easy to set up and very user-friendly. If you’re looking for a raid system synololgy is the best.
Solid Performer
The DS1821+ can handle just about any drive brand and model, unlike its newer cousins. I use one as a Plex media server and a second as backup. I added 10GbE NICs to both as 4X1GbE ports do not provide the bandwidth I want to experience - I don't use them at all. I added 2 450GB M.2 NVME SSDs to the mix for cache purposes and experience 100% cache hit rates. The Ryzen CPU doesn't have much oomph and transcoding suffers as a result. I use an N100 NUC to transcode. Plex does not transcode well when installed on the DS1821+ as it lacks the Intel Quick Sync capabilities. I've used Synology's devices for 13 years and have found that it is easy to perform all of the functions I want in a NAS device.
