M.2 2280 NVMe SSD SNV3410 400GB (SNV3410-400G)

Worked great on my RS1221+, easy to install. Overall my Synology is faster (local and online)

Little expensive but works like a charm in my Synology 1821+

I decided to add a second of these to my Synology NAS. It is (turning off the NAS first) plug and play and is fully compatible. It seems faster, but I also have three 6T drives in a 5 bay Synology NAS each with a 512 cache so how much faster I really can’t say. I don’t have the tools to analyze that.

Happy with this one, glad it works.

Synology has tried more to lock down their media and expansions, especially in the upper range of the product lineup. While you can find workarounds for the hard-disk nags and warnings about unsupported drives, I'm not so sure about SSD cache drives - I didn't try it, and these work OK but are quite pricey for what you get in capacity and performance. You're not going to get Gen 4x4 throughput here, and ultimately you need two drives to have some redundancy if you want to use them as cache. If you cache the metadata and such it does improve directory operations nicely, so it's worth doing it if you have a lot of files.

I used to use Dell servers with 120TB of RAID 10 to run Axis Camera station but their prices kept climbing and when they hit $30K I switches to Synology. Great reliable NAS and the solution is half the price of the Dell. I also run Camera station as a VM on the same NAS. This cache helps with with the Windows VM.

Perfect, new memory

Perfect fit and love having a M2 drive on my NAS

DS423+に組み込んで使用していますがストレージがSSDで、キャッシュもSSDだとファイル読み出しが早くて快適です。 ストレージがハードディスクがでも、SSDキャッシュがあるとなしでは読み出だしの体感速度が変わると思います。

Works well, 350MB/s seq write
