Buyer questions, answered directly

Test it with H2testw. The tool writes test files across the whole drive and reads them back, so it reports the capacity you can actually store data in — not the capacity the controller claims.

NAND dies are graded by how much testing they passed before being sold on, and the market describes three tiers. Original grade comes from the manufacturer fully tested and meeting full specification.

"Industrial grade" is not a single standard. It is a group of claims that should each be independently documented: an extended operating temperature range, a published endurance figure for total bytes written, a controlled bill of materials with a defined silicon source, and a long-term supply commitment.

Use approximate working figures per gigabyte: about 1,000 documents, 200 high-resolution photos, 250 songs, or around 40 minutes of 1080p video. That means a 32GB card holds roughly 6,400 photos or 21 hours of 1080p footage, and a 128GB card holds roughly 25,600 photos or 85 hours.

Yes. Every unit goes through capacity verification and read/write testing as part of our production flow, before packing — not as a separately requested extra that adds cost.

These three terms describe how a USB flash device is physically built, and they are often used loosely. COB (Chip-On-Board) refers to bonding the bare silicon die directly to the board instead of soldering a packaged chip — a manufacturing method.

USB-A is not going away, but it is no longer the safe default. New laptops and most phones are USB-C only, so a USB-A drive handed to a modern user may simply not fit.

Memory capacity is being absorbed by AI data centres at a rate the supply chain did not plan for, and the effect has reached consumer and component pricing. Published reporting during 2026 describes memory card prices rising by more than 100% year on year, projected increases in SLC NAND pricing of up to 170%, and industry stockpiles falling to under ten days of supply.

We are a manufacturer, not a trading company. The legal entity is Shenzhen Wintel Digital Technology Limited, registered in China since 2015, and we run our own flash memory production floor in Shenzhen — wafer sorting and testing, SMT assembly, moulding, printing and capacity verification all happen in-house.

Yes. On custom USB drives we apply your branding by silk-screen printing, full-colour printing or laser engraving, on metal, PVC or wood bodies, with bulk, retail or presentation packaging.

MOQ is not one number for every product. It is set by the capacity, the controller solution and how much customisation is involved, and it is confirmed against your specific quotation rather than read from a generic table.

Lead time depends on the configuration, the branding and whether tooling — a new mould — is needed, and it is confirmed in the quotation against your target date rather than taken from a fixed schedule. A repeat order of a product we already run is faster than a first order that needs a bespoke mould and artwork approval.

Price is set by the configuration you specify — capacity, interface, body material, branding method, packaging and quantity — not by a single list price. In the 2026 memory market, the silicon grade and the quotation validity period matter as much as the unit number, because flash pricing has moved sharply and a price quoted without a stated grade or validity window is not a commitment.

We supply project volumes to buyers in more than 50 countries, shipping from our facility in Shenzhen, China. Standard shipping terms and the departure method are confirmed per order, because they depend on your destination and whether you want the goods delivered to your door or collected at the origin.
