Hello Friends!
I am in the process of considering an SSD cache upgrade for my Synology DS1522+. My usage won’t primarily involve Docker containers and databases, but these features will be used from time to time, and I’m keen to maintain efficient performance.

My queries are as follows:

1. Storage Size for SSD: Given my occasional use of Docker and databases, what SSD capacity would be most suitable?
2. Influence of SSD Speed: To what extent does the speed of an SSD impact the performance of the caching process?
3. Single vs. Dual SSD Setup: Would having a dual SSD setup for caching provide a noticeable improvement over a single SSD?

I would greatly value your experiences or advice, especially if you have experience with SSD caching on a similar NAS model. Are there any specific brands or models you would suggest?

Particularly, I’m looking at these two models, currently available at significant discounts due to Black Friday sales in my region:

• Crucial P3 Plus 2TB
• WD Blue SN580 2TB

I would appreciate your input on which of these might be a better choice or if either is a worthwhile investment.

Thank you very much for your help!
