Flash memory products
In short
WINTEL produces four flash memory product lines, covering removable cards through to bare boards. TF cards at 15 × 11 × 1 mm, 4GB to 256GB, for devices with a card slot. UDP modules at 11.3 × 24.8 × 1.45 mm and semi-finished boards at 12 × 44 × 4.5 mm, 128MB to 128GB, for storage designed permanently into your product. And custom USB flash drives in metal, PVC and wood for branded products. Every line is available with USB 2.0 or USB 3.0 interfaces, A+ grade flash from named sources, and capacity, speed and housing specified to your project.

Clearance stock — overstock lots, sold while they last
Finished drives already in the warehouse: production overruns, cancelled orders and the tail of completed runs. Same build as a regular order, but the tooling, sample round and production slot behind them are already paid for — which is where the saving comes from.
Quantities are fixed and lots do not restock, so it suits giveaways, internal use and topping up a programme rather than a product you ship for years. Plain bodies can still carry your logo.
Choosing between them
The decision usually comes down to one question: should the storage be removable from your product or fixed inside it? Our guide to the three physical formats explains the trade-offs.
Which format fits your device
The three embedded formats carry the same flash inside, but they sit in different mechanical worlds. Match the storage to how your product is built, not to the headline capacity — the card reaches 256GB while the module and board stop at 128GB, and only the card is removable.
Removable storage in a card slot
TF card — 15 × 11 × 1 mm, 0.25 g, 4GB–256GB
- Your product has a sprung card socket
- Capacity may exceed 128GB (the card reaches 256GB)
- The end user may swap the card in the field
Storage soldered into the product
UDP module — 11.3 × 24.8 × 1.45 mm, 0.819 g, 128MB–128GB
- No card slot; the unit is potted COB and encapsulated
- Capacity stays at or below 128GB
- Shock load sits on the USB joint, not a latch
You own the final assembly
Semi-finished board — 12 × 44 × 4.5 mm, 3.2 g, 128MB–128GB
- You finish the housing and soldering in your own line
- Heaviest of the three at 3.2 g
- Best when you want to control the last build step
Branded giveaway or promo USB
Custom USB flash drives — metal, PVC, wood, moulded
- Your logo, shape and packaging on a finished drive
- A finished product, not an embedded component
- For marketing, events and resale
Frequently asked questions
Which product families does WINTEL manufacture?
Four: TF and microSD-class memory cards, UDP (USB Disk in Package) modules, finished USB flash drives, and semi-finished boards for buyers who assemble in-house. Each family is quoted separately because the tooling, test plan and MOQ differ.
What capacities are available?
Memory cards run from 4GB to 256GB. USB drives and UDP modules are quoted by the capacity you specify, from small-capacity promotional runs to high-capacity programmes. Availability at the top of the range depends on current NAND supply, so capacity is confirmed at quotation rather than assumed.
Can the products carry our branding?
Yes. Cards and drives can be printed or laser-engraved with your artwork, and packaging can be plain, printed or fully custom. Artwork is approved on a physical sample before bulk production starts.
How do I get pricing for a specific product?
Send the product family, capacity, quantity, branding requirement and target date. We reply to business enquiries within one business day with either a quotation or the specific questions needed to build one.
