When I think of NAS, there are always three brands that came to my mind. Synology, QNAP, and ASUSTOR. All three brands are from Taiwan. I reviewed Synology NAS many times and did my first QNAP NAS review in December.
To complete the trilogy, I have with me the Asustor Lockerstor 4 (AS6604T) which is equivalent to the Synology DS920+ and QNAP TS-453D. All three models are 4-bay NAS, powered by Intel Celeron J4125 and comes with 4GB of DDR4 ram. Intel J4125 is a 4-core 2.0 GHz (burstable to 2.7 GHz) processor.
QNAP TS-453D comes with only 4GB of RAM, and if you are going to do RAM intensive tasks like using Containers or Virtual Machines, you will definitely need to upgrade the RAM.
My second NAS 10 years ago was a decision between Synology NAS and QNAP NAS. In the end, I chose Synology. I can’t remember the reason why. Throughout all these years, I have been sticking with Synology NAS.
Synology DiskStation DS920+ is the highest end 4-bay NAS of the new Synology 2020 Plus series. Other models in the series include the DS420+ (4-bay), DS720+ (2-bay), and DS220+ (2-bay).
DS920+ has an Intel Celeron J4125 with 4GB of DDR4 ram. Intel J4125 is a 4-core 2.0 GHz (burstable to 2.7 GHz) processor.
