We need to output JSON with fields: seo_title, summary, key_entities (companies, people, locations), expert_faq (question, answer), internal_link_anchor, primary_keyword, secondary_keywords (list), content_type.

We must produce a polished 180-250 word summary, split into 3-4 paragraphs, each 45-65 words.

We need to bold a few key details using double asterisks. Must be selective, 3-5 bolded terms total.

We must follow anti-AI writing rules: avoid banned words, etc.

We must only include entities mentioned in source: companies: SanDisk? Actually source mentions "Sandisk P4", "Tom's Hardware", "Wolfy Tech" (YouTube channel). Also "Getty Images". Also "TH Premium"? Not a company. "Tom's Hardware". "Wolfy Tech". "Getty Images". Possibly "SanDisk". Also "TBW". Not a company.

People: Zhiye Liu (news editor at Tom's Hardware). Possibly also "Wolfy Tech" is a channel, not a person. Also maybe no other persons.

Locations: none explicit? Not mentioned.

We must not hallucinate.

We need to extract primary keyword: maybe "SSD endurance" or "TBW rating". 2-3 words. Let's choose "SSD endurance". Secondary: "NAND flash", "Terabytes Written", "MLC NAND", "Sandisk P4", "petabyte write test".

Content_type: likely "news" (timely experiment) or "article". It's a news about experiment. I'd choose "news".

Now craft summary 180-250 words, 3-4 paragraphs each 45-65 words.

Let's aim for 3 paragraphs, each ~55-60 words => total ~165-180. Need 180-250, maybe 4 paragraphs each ~55 => 220. Let's do 4 paragraphs each ~55-60 => total ~220-240.

Paragraph 1: introduce experiment: 16-year-old Sandisk P4 SSD survived 1 petabyte writes, 25x TBW rating. Bold Sandisk P4 maybe, also 1 petabyte.

Paragraph 2: context about TBW, warranty, MLC NAND vs modern TLC/QLD, mention 32nm MLC NAND, 40 TBW rating. Bold 40 TBW maybe.

Paragraph 3: details about power-on hours, 60k hours, 1,100 power-ups, no catastrophic failure, mention Wolfy Tech YouTube channel. Bold Wolfy Tech maybe.
