### ⭐⭐⭐⭐⭐ Works

Works as advertised

### ⭐⭐⭐⭐⭐ Great expansion unit
*by M***A on 7 January 2026*

Work well with 3rd party drives!

### ⭐⭐⭐⭐⭐ I'm very happy with my 1621+
*by R***S on 22 August 2023*

I've owned a Synology 1512+ since 2012. It was great, but it was time to get a new Synology. There was no question regarding what brand to get, which is a Synology. After my research, I found that the 1621+ with 32 Gig RAM and a 10GB Ethernet adaptor was the perfect choice. I loaded this up with the Seagate IronWolf 12GB X 6 NAS 7200 RPM 256MB cache drives = 60TB and 42TB after the SHR-2 Raid configuration. This thing is halling!!!! It's very fast, responsive and the new DSM 7.2 OS works great! When you all get one of these, please get a UPS as always to keep the machine safe! You will really like this product as I do.
