The Problem We Solve

Consumer cards die in continuous-recording jobs. That's your return rate.

A dashcam or security camera writes around the clock; a consumer microSD is built for occasional bursts. Put one in a 24/7 job and it wears out in months — the light stays green, but the footage isn't there when it matters. The fix isn't guesswork, it's grade: match the NAND endurance to the duty cycle, and quote from the card's datasheet TBW, not a marketing "hours" sticker.

Why Source-Factory

The endurance is only as good as the supplier behind it

A high-endurance spec means nothing if the next batch quietly swaps to cheaper NAND. Source-factory control is the whole point.

01
Published TBW & P/E

Endurance stated per SKU on the datasheet — you quote and qualify against numbers, not a sticker.

02
100% H2testw tested — verify it yourself

Every card capacity-tested with a report per batch, and you can re-run H2testw on arrival. No co-mingled inventory, no marketplace mystery stock — straight from the line, batch-traceable. We publish the guaranteed usable-capacity floor most sellers hide.

03
Locked & traceable

BOM, controller and firmware fixed per order, locked part numbers, every batch traceable — no silent swaps wrecking your RMA rate.

04
Allocation, confirmed at order

Authorized agent of an IATF 16949 source factory — stable lead times through the 2026 NAND shortage.

FAQ

High-endurance microSD — sourcing questions

Why does my dashcam or security-camera SD card keep dying after a few months?
Because a consumer card was put in a continuous-overwrite job it was never rated for. A camera writes around the clock, and a standard 3D TLC card (~1,000–3,000 P/E cycles) wears out in months — often silently, so the card looks fine until you need the footage. Heat in a parked car (up to ~60°C) makes it worse. The fix is grade, not brand: a high-endurance or pSLC card rated for the duty cycle, quoted against datasheet TBW.
Is an A2 card worth it for a dashcam or surveillance camera?
For recording, no — A2 is widely over-chased. The A2 badge rates random read/write IOPS, which matters for running apps off a card, not for the large sequential writes a camera produces. What a recording card needs is sustained write speed (V30/U3) plus endurance (TBW / P/E). Pay for endurance and the right speed class, not the A2 sticker.
How do I know your cards aren’t fake or re-flashed like marketplace stock?
Every card is 100% H2testw capacity-tested with a report per batch, and you can re-run H2testw the moment it arrives. Stock comes straight from the source-factory line — no co-mingled marketplace inventory where a genuine listing can ship a counterfeit. Batches are traceable and the BOM is locked per order, so the cards you qualify are the cards you re-order.
What makes a microSD "high endurance"?
Endurance is governed by NAND program/erase (P/E) cycles, not by speed. A consumer 3D TLC card survives roughly 1,000–3,000 P/E cycles; a high-endurance card uses higher-grade NAND or runs cells in 1-bit pSLC mode for ~20,000+ cycles. That difference is what turns total writable data (TBW) from about a year of 24/7 recording into several years. A "high-endurance" label only means something when the datasheet states the TBW and P/E figures behind it.
Do you supply pSLC on request, or TLC with an endurance label on it?
Both grades exist, and we state which one you are quoting. pSLC (MLC/TLC run in 1-bit mode) and high-endurance TLC are different products with different TBW and price points — we put the NAND mode and rated TBW on the quote and the datasheet, not just the word "endurance" on the sticker. Trial-batch verification is welcome before you commit to volume.
Can you OEM our brand on the cards?
Yes. White-label silkscreen or laser marking, custom retail packaging, fixed BOM and controller/firmware lock per order, and locked part numbers so re-orders match the batch you qualified. Both finished retail cards and bulk/bare are available.
What is the MOQ and lead time during the 2026 NAND shortage?
As an authorized agent of a source factory we confirm price and lead time at order, so they hold firm while spot-market supply dries up. MOQ runs from carton level for resellers up to volume tiers for distributors. Tell us capacity, grade and monthly volume and we return a real factory quote, usually the same business day.
