SanDisk Extreme PRO 512GB microSDXC Memory Card 200MB/s with SD Adapter

Engineered for high-speed performance, this card delivers read speeds up to 200MB/s and write speeds of 140MB/s. It features A2-rated app performance and V30 video speed class for reliable 4K UHD recording on drones, action cameras, and smartphones. The durable design is waterproof, shockproof, and X-ray proof to protect data in extreme environments.

The SanDisk Extreme PRO 512GB microSDXC Memory Card – SD Adapter Included is the top of SanDisk’s UHS-I microSD range — 200MB/s read and 140MB/s write, the fastest available in the UHS-I format. A2 rating means faster app loading on Android. V30 guarantees minimum 30MB/s sustained write for reliable 4K recording. At 512GB, there is enough room for around 25–30 hours of 4K footage at action camera bitrates, or over 100,000 RAW photos, or a substantial game library on Nintendo Switch. Built for outdoor conditions: waterproof, shockproof, extreme temperature rated, and X-ray safe. SanDisk backs it with a lifetime limited warranty and includes RescuePRO Deluxe data recovery software. The SD adapter enables use in DSLR and mirrorless camera slots or laptop SD readers.

Speed

200MB/s Read · 140MB/s Write

200MB/s read exceeds the standard UHS-I ceiling of 104MB/s — transferring a 10GB video file takes around 50 seconds rather than minutes on slower cards. 140MB/s write is the critical number for videographers: it keeps the camera buffer clear during continuous 4K recording, preventing dropped frames even at high bitrates. V30 provides the minimum guaranteed 30MB/s floor for reliable video capture. A2 rating delivers faster random I/O for app loading and better performance on Android. Note: full speed requires a compatible UHS-I host device or reader.

Capacity

512GB — Shoot Without Limits

512GB holds approximately 25–30 hours of 4K video at typical action camera bitrates, over 100,000 RAW files at 20MP, or a large Nintendo Switch game collection. For multi-day trips, events or shoots where stopping to offload or swap cards is not practical, 512GB provides genuine working freedom. The included SD adapter means the same card works directly in DSLRs, mirrorless cameras and laptops with SD slots — one card, multiple devices. Need even more? See the Extreme PRO 1TB.

Durability

Built for the Field

Waterproof, shockproof, extreme temperature rated (-25°C to 85°C operating) and X-ray safe. Built to handle the conditions that come with adventure and professional capture — rain, drops, airport security and large temperature swings between environments. RescuePRO Deluxe data recovery software (download offer) helps recover accidentally deleted files. Lifetime limited warranty is SanDisk’s strongest warranty tier, covering the card for its working life.
