Why this product
Fast read speeds for quick media transfers
Read speeds reach up to 190MB/s on 64GB–1TB capacities and up to 240MB/s on the 2TB, powered by SanDisk QuickFlow™ Technology. Note that exceeding the UHS-I 104MB/s ceiling requires a compatible host device.
U3 and V30 rated for 4K UHD recording
UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) ratings ensure sustained write performance needed for uninterrupted 4K UHD and Full HD video capture.
A2-rated for fast app performance
The 64GB–2TB capacities carry an A2 rating (4000 read IOPS, 2000 write IOPS), making them well-suited for running apps directly from the card on Android smartphones.
Built to survive tough conditions
It is rated waterproof, shockproof, temperature-proof, and X-ray-proof, so it can accompany you on shoots in challenging environments without extra protection.
Lifetime Limited Warranty included
Every card is covered by a Lifetime Limited Warranty (30-year warranty in Germany, Canada, and regions that do not recognise lifetime warranties).
RescuePRO Deluxe recovery software included
A download offer for RescuePRO Deluxe data recovery software is included, giving you a path to recover accidentally deleted files (download required).

- Compatible with devices that accept microSDHC UHS-I or microSDXC UHS-I cards, including Android smartphones, action cameras, drones, laptops, and handheld gaming consoles.
- Works in any standard microSD or SD slot when used with the included SD adapter.
- Read speeds above 104MB/s (including QuickFlow™ Technology speeds on 64GB–2TB) require a host device capable of exceeding the standard UHS-I 104MB/s ceiling.
- Maximum speeds are achieved when paired with the SanDisk Professional PRO-READER SD and microSD (sold separately).
- The 32GB card uses the microSDHC format; devices that only accept microSDXC will not read it, and vice versa for very old devices that predate microSDXC.
- Not compatible with devices that require a proprietary memory card format (e.g., CompactFlash, CFexpress, XQD).
Best for
- Action camera and drone users who need sustained 4K UHD write performance — U3/V30 ratings and write speeds up to 130–140MB/s on larger capacities support continuous high-bitrate recording.
- Android smartphone users looking to expand storage and run apps from the card — the A2 rating (4000 read IOPS, 2000 write IOPS) on 64GB–2TB capacities is designed for this use case.
- Adventurers and outdoor creators who need a card that can handle harsh conditions — the waterproof, shockproof, temperature-proof, and X-ray-proof construction provides broad environmental durability.
- Handheld gaming console users who want a large, fast card for game library expansion, with capacities available up to 2TB.
- Creators who value data safety — the included RescuePRO Deluxe download offer and Lifetime Limited Warranty add a recovery and support layer on top of the hardware.
Trade-offs
- Users with standard UHS-I devices who expect the top-rated read speeds — speeds above 104MB/s require a compatible device; on standard UHS-I hardware, throughput is capped at the UHS-I limit regardless of card rating.
- App-intensive smartphone users choosing the 32GB — the 32GB is A1-rated (1500 read IOPS, 500 write IOPS), which is lower than the A2 rating available on all larger capacities.
- Users who need the fastest transfer speeds without a dedicated card reader — maximum rated speeds require the SanDisk Professional PRO-READER SD and microSD, sold separately.
- Devices requiring formats other than microSD — this card is not compatible with CompactFlash, CFexpress, XQD, or other proprietary card formats.
Capture epic 5K point-of-view and 4K UHD aerial video – plus expand Android™ device, laptop, and handheld gaming console storage – with the SanDisk Extreme® microSD™ UHS-I card made for enthusiasts and creators. Record longer and save more with up to 2TB of storage.
The SanDisk Extreme microSDXC™ memory card lets you save time transferring media with read speeds of up to 190MB/s powered by SanDisk QuickFlow™ Technology (64GB–1TB). Pair with the SanDisk Professional PRO-READER SD and microSD™ to achieve maximum speeds (sold separately). With write speeds up to 130MB/s, it's ideal for your Android™ smartphone, action cameras, or drones. This high-performance microSD™ card handles 4K UHD video recording, Full HD video, and high-resolution photos.
Plus, it's A2-rated, so you can get fast application performance for an exceptional smartphone experience.
SanDisk Extreme microSDHC™ and microSDXC™ UHS-I Cards are shockproof, temperature-proof, waterproof, and X-ray-proof, so you can enjoy your adventures without worrying about the durability of your memory card.
The card comes with a RescuePRO Deluxe data recovery software download offer. This software makes it easy to recover files that have been accidentally deleted (download required).
