HDD Cache Size
When it comes to media streaming, a larger HDD cache (256MB vs. 128MB) typically doesn’t make a significant difference. The primary role of the cache is to speed up access times for frequently accessed data, but for streaming media, the bottleneck is more often your network speed rather than the cache size. Given the significant price difference, sticking with a 128MB cache should be sufficient for your needs.

WDDA 3-Year Warning and WD as a Company
Regarding the WDDA (Western Digital Device Analytics) 3-year warning, it’s essential to keep firmware updated and follow best practices for drive health monitoring. While this warning can be concerning, it is a proactive measure to ensure drive reliability over time. As for the previous SMR (Shingled Magnetic Recording) issue, it’s true that WD faced criticism for not clearly disclosing which drives used SMR technology, which can impact performance in certain NAS configurations. Synology have removed this warning.

Despite these concerns, WD remains a reputable company with a solid track record in the storage industry. They offer a range of products suited for different needs, and their WD Red NAS drives are still a popular choice for many users. However, it's always good to stay informed about potential issues and consider alternatives like Seagate IronWolf drives if you’re looking for additional peace of mind.
