Maximize your device's potential with the high-performance SanDisk Ultra 256GB microSDXC UHS-I Memory Card. Whether you're a content creator, mobile gamer, photography enthusiast, or someone who simply demands more space, this card delivers the storage capacity, transfer speeds, and application performance you need.

This model (SDSQUA4-256G-GN6MA) arrives complete with a full-sized SD adapter, ensuring compatibility across virtually every device that supports removable media. From smartphones and tablets to cameras, laptops, and gaming consoles, this single solution covers all your storage requirements.

💾 Massive Storage Capacity

The 256-gigabyte capacity is a game-changer for users who have outgrown their device's built-in memory. This vast storage space accommodates:

• Video Content: Up to 16 hours of Full HD (1080p) video footage, enough for extended trips, events, or vlogging sessions without interruption

• Photography: Tens of thousands of high-resolution images, enabling professional-grade photoshoots or family vacations without switching cards

• Music Collection: An expansive audio library containing over 50,000 songs encoded at 320kbps MP3 quality

• Mobile Applications: Hundreds of apps and games, transforming your device into a multimedia powerhouse

• Gaming Libraries: On platforms like Nintendo Switch, this capacity stores approximately 15-20 full game downloads, eliminating the need to juggle multiple cartridges

💡 Capacity Note: The total available storage will be slightly less than 256GB due to formatting overhead and system file allocation. 1 gigabyte equals 1,000,000,000 bytes, and actual usable capacity may be lower .

⚡ Exceptional Transfer Speeds

This card achieves read speeds of up to 120 MB/s, making file transfers remarkably swift and efficient. This velocity is made possible through advanced proprietary technology that pushes the boundaries of the UHS-I interface.

Real-world transfer examples:

• Photo Backup: A folder containing 1,000 high-resolution JPEG images (approximately 4.1GB total) transfers to your computer in under 40 seconds using a USB 3.0 card reader

• Video Offloading: A 2-hour 1080p video file (approximately 15GB) moves from card to computer in roughly 2 minutes

• Daily Syncing: Routine backups happen so quickly you won't notice the wait

What affects the speed?

• The host device's card reader capabilities

• USB version (USB 2.0 vs. USB 3.0)

• File fragmentation and type (many small files transfer slower than one large file)

• System overhead and background processes

⚙️ Performance Note: Write speeds are generally lower than read speeds. The card's write performance typically ranges between 10-40 MB/s depending on usage conditions. This is normal and within specifications for this product class .

📱 A1-Rated Application Excellence

The A1 (Application Performance Class 1) certification is one of the card's most valuable features for mobile users. It guarantees exceptional random read and write performance, measured in Input/Output Operations Per Second (IOPS):

What A1 means for you:

• Lightning-fast app launches: Open applications stored on the card without frustrating delays

• Smooth gameplay: Games load levels and assets quickly, maintaining immersion

• Responsive multitasking: Switch between apps effortlessly when using Adoptable Storage on Android

• Improved system performance: The device doesn't stall when accessing external storage

• Seamless photo viewing: Scroll through galleries without waiting for thumbnails to populate

For Android users employing Adoptable Storage, the card effectively becomes an extension of internal memory. The A1 rating ensures this expanded storage doesn't compromise your device's responsiveness—a critical advantage for budget and mid-range smartphones with limited internal capacity.
