Q4 2026 buying checklist: DDR4 tail, DDR5 allocation, microSD grades
DDR4 supply is thinning, allocation is the constraint on DDR5, and microSD buyers are being asked to justify endurance grades. A short checklist for the quarter.
Read moreLabelling, packaging, firmware and MOQ — a practical checklist for launching an SSD line under your own brand.

Start with the label, not the drive. A private-label SSD lives or dies on whether the printed specification matches the drive underneath: model name, capacity, interface, form factor and warranty statement all have to be agreed in writing before tooling starts, because changing a label after the first run means scrapping packaging.
Firmware is where the quiet work sits. Ask for the SMART attribute set, the over-provisioning policy and the power-loss behaviour in writing, then test a sample batch with your own tooling — CrystalDiskMark, fio or a burn-in rack all work. A supplier who cannot answer those three questions is reselling, not manufacturing.
Then commercialise: MOQ per capacity, tooling cost and whether it is one-off or amortised, lead time from purchase order to ex-works, and the RMA rate you are willing to accept in the contract. A programme with a 3,000-piece MOQ and a documented RMA process beats a cheaper one with neither.
