Samsung 512GB PRO Plus UHS-I microSDXC Memory Card

512GB of Samsung-grade NAND in a microSD card — the practical maximum capacity for users who want to carry their entire creative library, game collection or media archive on a single card. The Samsung 512GB PRO Plus UHS-I microSDXC Memory Card delivers 180MB/s read and 130MB/s write, clearing a full 512GB to a laptop in around 47 minutes and sustaining 4K UHD video recording and high-speed burst sequences without buffer stalls. The A2 rating meets the random I/O requirements for smooth app and game performance when the card is used as expandable storage. Six-layer protection covers waterproofing (72 hours in seawater), temperature extremes, X-ray exposure, magnetic fields, 5-metre drops and 10,000 insertion cycles. Samsung produces the NAND and controller firmware in-house — the same manufacturing line that supplies Galaxy smartphones. 512GB stores approximately 17 hours of 4K 30fps video or over 10,000 RAW photos before requiring clearing. Backed by a 10-year limited warranty — among the longest available on any microSD card.180/130 MB/s4K Video · Burst Shooting · Fast Transfer180MB/s sequential read transfers a full 512GB card to a laptop in approximately 47 minutes. 130MB/s write sustains 4K UHD recording on compatible devices and handles sustained RAW burst sequences without the camera's internal buffer holding back the shot count. V30 guarantees a minimum of 30MB/s sustained write — the SD Association's threshold for reliable 4K UHD video capture at all times, regardless of card fill level. U3 confirms the same minimum for UHS-rated devices. For GoPro and DJI drone users, these are the specs that determine whether footage is captured cleanly or interrupted mid-recording. 130MB/s write makes this card particularly capable for continuous action sequences that push the camera's buffer hard.512GB CapacityFull Project Archive — Nintendo Switch Game Library512GB holds approximately 17 hours of GoPro Hero 4K 30fps footage, or a full multi-week trip's worth of 24MP RAW photography — around 10,000 images. For Nintendo Switch users, 512GB stores the entirety of most game libraries: 40–50 full-size Switch titles simultaneously, eliminating the need to delete games to manage card space. For Android users running apps from expandable storage, A2 performance (4,000 random read IOPS, 2,000 write IOPS) ensures apps launch at normal speed rather than the noticeable lag that lower-rated cards produce. The Samsung Memory app can automatically move files and apps between phone storage and the card to optimise space.6-Proof · 10-Year WarrantySamsung NAND — Maximum Capacity, Maximum ConfidenceAt 512GB, the data concentrated on a single card — weeks of footage, thousands of irreplaceable RAW files — is substantial. Samsung's six protection layers cover: waterproof (72 hours in seawater), temperature-proof (-25°C to 85°C), X-ray proof (up to 100mGy at airport security), magnet-proof (15,000 gauss), drop-proof (5 metres), and wearout-proof (10,000 insertion cycles). Samsung manufactures all NAND flash and controller firmware in-house — no third-party components — ensuring quality control at every level. The 10-year limited warranty reflects Samsung's confidence in the durability of this flash at 512GB capacity, and provides long-term coverage well beyond most competing cards' 3–5 year warranties.Great choice if you…✔ Record 4K video and need all-day capacity without card swaps✔ Want maximum Nintendo Switch or Steam Deck game storage✔ Shoot multi-day photography projects in RAW format✔ Use a GoPro, DJI drone or Android smartphone for heavy use✔ Want a 10-year warranted card backed directly by SamsungConsider something else if…✖ You need 200MB/s read speed — see Samsung PRO Ultimate✖ 256GB is sufficient — available at a lower price✖ You need extended endurance for dash cams — see Samsung PRO EnduranceTechnical SpecificationsBrand / ModelSamsung PRO Plus microSDXCCapacity512GBRead SpeedUp to 180MB/sWrite SpeedUp to 130MB/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 512GB microSDXC card—SD adapter (full-size)Compatible With—Android smartphones and tablets (microSD slot)—GoPro action cameras · DJI drones—Nintendo Switch · Steam Deck—Mirrorless and DSLR cameras with microSD slot—Cameras and laptops with SD slot (via adapter)ConditionBrand New — Retail PackagingWarranty10 Years SamsungDelivery4–5 Working Days · Fully TrackedAlso available: Samsung PRO Plus 256GB.
