Samsung 128GB PRO microSDXC Memory Card – UHS-I U3 A2 V30 160MB/s with Adapter

The Samsung 128GB PRO microSDXC Memory Card – UHS-I U3 A2 V30 160MB/s with Adapter is Samsung's performance tier memory card for everyday high-demand use. 160MB/s sequential read and 120MB/s write keep pace with 4K UHD video recording on compatible devices and handle rapid JPEG burst sequences without the camera buffer stalling. The A2 rating means apps stored on the card run smoothly rather than lagging behind internal storage. Six-layer protection covers seawater immersion, extreme temperature ranges, airport X-ray exposure, magnetic fields, 5-metre drops and 10,000 insertion cycles. Samsung produces all firmware and NAND in-house — the same chip technology found in Samsung Galaxy phones. 128GB provides enough storage for a full day of 4K shooting or thousands of high-resolution photos. The 10-year limited warranty is among the longest available on any microSD card. SD adapter included for cameras and laptops.160/120 MB/s4K Video · Burst Shots · Fast Transfer160MB/s sequential read transfers a full 128GB of footage to a laptop in around 13 minutes. 120MB/s write sustains 4K UHD video recording and handles high-speed JPEG burst sequences without camera buffer stalls. V30 (Video Speed Class 30) guarantees a minimum sustained write of 30MB/s — the SD Association's threshold for reliable 4K UHD video capture. U3 confirms the same minimum for UHS-rated devices. Both are guaranteed minimum specifications rather than peak figures, ensuring consistent performance across the full capacity. For smartphones, action cameras and drones requiring a fast, reliable microSD card at 128GB, the PRO Plus delivers Samsung quality at a practical price point.A2 Performance4,000 IOPS — Smooth App LoadingA2 (Application Performance Class 2) requires 4,000 random read IOPS and 2,000 random write IOPS — the random I/O performance that determines how fast apps launch and run when stored on expandable storage. For Android users installing apps, games and media to a microSD card, A2 means normal-speed performance rather than the sluggishness of lower-rated cards. For Nintendo Switch users expanding game storage, A2 ensures load times that are competitive with internal storage. The PRO Plus meets this specification, making it suitable for both media storage and active app use on any compatible device.6-Proof · 10-Year WarrantySamsung NAND — Built to LastSix verified protection layers: waterproof (72 hours in seawater), temperature-proof (-25°C to 85°C), X-ray proof (up to 100mGy), magnet-proof (15,000 gauss), drop-proof (5 metres) and wearout-proof (10,000 insertions). Samsung manufactures all NAND flash and controller firmware in-house — the same production line that supplies Samsung Galaxy internal storage. The 10-year limited warranty is direct from Samsung and covers the card under normal use for a decade. Note: the warranty does not extend to dash cam, CCTV or surveillance camera applications. For those use cases, Samsung's PRO Endurance card is the correct choice. The SD adapter carries a 1-year warranty.Great choice if you…✔ Record 4K video on a smartphone, action camera or drone✔ Shoot high-resolution photo bursts and need fast write speed✔ Store and run apps on microSD (A2 performance required)✔ Want a 10-year warranted card backed by Samsung✔ Use GoPro, DJI drone, Nintendo Switch or Samsung GalaxyConsider something else if…✖ You need 180MB/s+ speeds — see Samsung PRO Plus 256GB (newer spec)✖ You need extended endurance for dash cams — see Samsung PRO Endurance✖ You need 256GB or 512GB — see larger capacities in the PRO Plus rangeTechnical SpecificationsBrand / ModelSamsung PRO Plus microSDXCCapacity128GBRead SpeedUp to 160MB/sWrite SpeedUp to 120MB/sSpeed ClassUHS-I · U3 · V30 · A2 · Class 10Video4K UHD · Full HDProtectionWater · Temperature · X-ray · Magnet · Drop · WearoutWeightApprox. 0.25gWarranty10 Years Samsung (card) · 1 Year (adapter)Box Contents—Samsung PRO Plus 128GB microSDXC card—SD adapter (full-size)Compatible With—Android smartphones and tablets (microSD slot)—GoPro action cameras · DJI drones—Nintendo Switch—Dash cams · body cams (standard use)—Cameras and laptops with SD slot (via adapter)ConditionBrand New — Retail PackagingWarranty10 Years SamsungDelivery4–5 Working Days · Fully TrackedAlso available: Samsung PRO Plus 256GB.
