Synology DiskStation DS1621+ 6-Bay NAS Server, AMD Ryzen V1500B Quad Core 2.2 GHz, 4GB RAM, 2x M.2 2280 NVMe Slot, 4x GbE, 2x eSATA, 3x USB3.2 Gen1, 1x PCIe Expansion Slot, 3 Years Warranty

When my DS1515+ plus died due to the special intel atom bug, I started looking at replacement NAS. The DS1621+ was a good choice as it comes with 6 bays, only used 4 bays in the previous NAS. This 6 bay NAS allows me now to plan to say get 2x 8tb/10tb then I can copy all the data from the 4 drives to the 2x 8tb/10tb pool decommission the 4 drives and then add more drives to the empty bays and increase storage capacity. I prefer Ryzen processor over Celeron's, time will tell if I made the right choice.

I plugged in my old drives followed the prompts and had my data back. Just note this only works going from one Synology to another Synol...view more When my DS1515+ plus died due to the special intel atom bug, I started looking at replacement NAS.

Excellent and well made product. True, you look at the price, and initially you feel you could build a NAS yourself - but this is fast, the software is a delight and I am very pleased. Have added more disks, used the cache (2x needed for RAID requirement for R/W cache), and installed a cheap 10G card. The main advantage of the 1621+ over the 1522 is the availability of the slot, and ability to upgrade the networking to 2x10G inexpensively. Very pleased. Excellent and well made product.

I paid a bit more than I wanted to for this Synology NAS but I'm glad I did. It is so easy to set up. You plug it in, install your hard drives by just sliding them into the unit, connect it to your router and switch it on. Once you have installed the GUI your all set. I use it for PLEX, my digital music files and backing up my business files. I just works and is so versatile. If you need help to get it up and running there are literally hundreds of You Tube videos showing you how to get it to do anyting and everything you could possibly want your NAS to do.

The DS1621+'s six bays allow one to use RAID6 (or the Synology equivalent of that) which supports losing two of the six disks without losing any data, while still supporting the same amount of storage that a 4-bay NAS would offer without any redundancy.

Unlike the fans on my DS420+, the fans of the DS1621+ are very quiet (it is not a matter of fan speed, they just don't have that annoying ticking sound) and I can recommend the DS1621+ as a storage solution due to the very user-friendly software. Just note that all four network ports only support 1Gbs, i.e., are not even 2.5Gbs ports. However, with the recent SMB3 multichannel support one ...view more The DS1621+'s six bays allow one to use RAID6 (or the Synology equivalent of that) which supports losing two of the six disks without losing any data, while still supporting the same amount of storage that a 4-bay NAS would offer without any redundancy.

Just note that all four network ports only support 1Gbs, i.e., are not even 2.5Gbs ports. However, with the recent SMB3 multichannel support one can use multiple ports at the same time, multiplying transfer speeds accordingly. Also, one may add a 10Gbs card. Unlike newer Synology NAS models, the DS1621+ still supports the addition of any PCIe-based 10Gbs network card; newer versions only support the proprietary Synology-extension card which is pricier than comparable hardware.

Also note that since the DS1621+ uses an AMD Ryzen CPU, it is less than ideal to be used as a media server. If you want your NAS to transcode videos on the fly so that you can watch them on devices that do not support the original video format, e.g., run a Plex media server on your NAS, you'd be better of with a model that uses an Intel CPU with "quick sync" technology.

This is a great product, I really like the SynolgoyDSM and use this to host multiple services as well as a NAS. Very easy to use and setup, though I would get some extra RAM.

Upgraded from a DS718+ and got this!. You'll probably need more to purchase more RAM, so look out for bundle deals! Upgraded from a DS718+ and got this!. You'll probably need more to purchase more RAM, so look out for bundle deals!
