What to Write into a Flash Memory Purchase Specification
A purchase specification is the document that lets a supplier repeat what you approved. It should state, in verifiable terms, the product, capacity, performance, silicon source and grade, controller, appearance, packaging, test method and commercial terms. The discipline that matters is writing things so they can be checked — a grade in writing, a speed as a test, a sample retained — rather than as adjectives. This is what keeps a reorder identical to the approved sample instead of a pleasant surprise.
Clauses a specification should contain
| Clause | Must be… |
|---|---|
| Product and capacity | Stated exactly, with usable vs nominal noted |
| Performance | A test, not a slogan — sustained write MB/s, class |
| Silicon source and grade | Named and written, not "high quality" |
| Controller | Specified where the host demands it |
| Appearance and branding | Referenced to artwork and sample |
| Packaging | Type and quantity per carton |
| Test and acceptance | Method, sampling, pass/fail, handling |
| Commercial | Incoterms, price validity, lead time |
Make each clause verifiable
Write the grade you will accept, the speed as a test you will run, and keep a tested sample. A specification full of adjectives cannot be enforced, and the gap is exactly where substitutions appear.
Carry it into acceptance
The specification is also your acceptance reference. The clauses you wrote are the clauses you re-check on arrival, so write them as things a technician can measure.

How detailed must the first specification be?
Enough to quote and to test. Product, capacity, grade and a performance test are the core; the rest can be filled as the sample stage progresses. You do not need a 20-page document to start.
Does the specification replace the sample?
No. The sample is the physical proof; the specification is the written rule. Keep both — the retained sample is what you compare a disputed batch against.
How do I keep reorders identical?
Lock the configuration in the specification and reorder against the same written clauses. See how to keep repeat orders consistent.
