Silo architecture for personal blog

Hi guys,

I'm in the midst of studying about silo architecture for my blog. Is it really good for page ranking?
My current blog is about Tech, product reviews, How-to, apps & tech news. Is it consider only one niche?

If implement silo structure for my blog, should i change the home page to static page(With link to categories)? Really a bit confuse about this.

Do you guys have any similar silo structure blog for me to referring?
