I buy this NAS for the 2.5 LAN .. I haven't fully tested it yet... but I want to say that the packaging and delivery were EXCELLENT.


Easy to upgrade memory took sodimm ddr4 3200 16 gig. Qnap went to soldered on memory on new machines suppossedly due to a ram shortage so now you can not upgrade their ram so this was a HUGE no no for me. I was a Qnap lover, but a friend has a older version of this and I thought i'd give em a try. Software looks almost identical to a Qnap so was easy for me to get in and go. 2x2.5 gb networking. it does transfer very quickly. 4X Gen 3 m.2 (NOTE THESE GET HOT). I used heat sinks for all 4 and have had zero problems. It's worth a few bucks to toss heat sinks on em. if your only going to cache boost with em get small cheapies they run much cooler. Took a few tries to get the setup I wanted with my raid and SSD caching. This was a neck and neck with Qnap ts464. its cheaper and does the same stuff, but you can upgrade the ram. I have both this and the Qnap ts464 this is my favorite. This thing for Plex is a beast! transcodes multiple streams like a champ.

- M.2SSD and 10GBE in one card - Performance - Ease of installation - Heat sink


I purchased this DS1621+ to replace my aging Netgear RN316, 11 years old. Wow, a lot faster at read/write as well as maintenance functions such as scrubbing. I look forward to diving into its functionalities and remote access.

Very fast with link doubling. Easy to replace two of SATA 2.5/3.5" disks. Very convenient setup with four M2 NVMe memories. Multiple functionality and apps. Fast USB 3 connections for additional external disks. Very fast internal copy/move operations.

Easy to setup and configure


This QNAP runs quickly and quietly. The VM is Microsoft Server 2019, and it is very fast. I have it configured to boot off of a RAID-1 SSD drive array, and the AMD Ryzen processor is very fast. Adding RAM and the SSD drives was EASY. Very nice design on the case, easy access 3 screws and that was it. I added five 16-TB drives in RAID-5, and it is used as a Veeam Offsite Repository target server.

Happy to have 6 gb total all working ; didnt want to take a risk to go above 6 gb that isnt on the compatibility list

- 10GB works well - cache drives work well


The product was easy to set-up for someone like me who is not a computer expert but with an above average level of computer knowledge.
