DC HC560 vs 570

[Enquiries]

Hi,

I was searching a lot do you please see any benefit of buying DC HC570 vs DC HC560? It seems 570 has Armor Cache, but maybe it's a marketing gimmick. 570 is 80 EUR more expensive than older generation (2021) 560 (there are 2 versions). It also seems WD says HC570 has 2nd generation OptiNAND whatever it means...Power consumption is higher for 570, by adding 2TBs maybe it's actually not worth it...
I will use it in 916+ Synology mainly for storing photos

thanks a lot to everyone for anwers

The main difference between the WD DC HC560 and DC HC570 drives is that the HC570 features the ArmorLock Security Platform, which provides advanced data security features such as encryption and access control. The HC570 also has a slightly higher maximum sustained transfer rate and a slightly higher random read performance than the HC560.

The OptiNAND technology in the HC570 refers to a small amount of NAND flash memory built into the drive's controller, which can be used to improve drive performance and reliability. However, the benefits of this technology may be difficult to measure in real-world use.

In terms of power consumption, the HC570 does have a slightly higher power draw than the HC560, but the difference may not be significant enough to be a major factor in your decision.

Overall, if data security is a concern for you and you can afford the extra cost, the HC570 with ArmorLock may be a better choice. However, if you don't need the advanced security features and are looking to save some money, the HC560 may be a good option.
