Overview

The SanDisk SDXC UHS-I 512GB is a high-performance SD memory card designed for compact point-and-shoot and mid-range cameras. With read speeds up to 150MB/s, it enables fast transfer of large photo libraries and Full HD video files to your computer. The card meets UHS Speed Class 1 (U1) and Class 10 standards, ensuring smooth Full HD (1080p) video recording without dropped frames. This 512GB model offers ample storage for thousands of photos or hours of Full HD footage. SanDisk's proprietary technology pushes beyond the standard UHS-I 104MB/s ceiling, making it a solid choice for everyday photography, travel, and casual videography.

Connectivity & Compatibility

The card works with any device that has an SD card slot, including cameras, camcorders, laptops, and external card readers. For maximum read speeds up to 150MB/s, a UHS-I compatible host device and a SanDisk SD UHS-I card reader (sold separately) are required. When used in non-UHS-I devices, performance falls back to standard SDHC/SDXC speeds. Full HD (1920x1080) video recording is supported, but 4K or 8K video capture is not. Always check your camera's compatibility list for 512GB SDXC cards before purchasing.

Product Info

Released around 2022, the SanDisk SDXC UHS-I 512GB typically retails for approximately ¥12,000 in Japan. It comes with a limited 10-year warranty (subject to manufacturer terms). The package includes only the SD card itself; no case or reader is included. This card sits in the entry-to-mid-range segment, offering a balance of speed and capacity at a price point well below professional-grade CFexpress or XQD media. It is a practical upgrade for users moving beyond basic SDHC cards.

Best Use Cases

Compact camera and entry-level DSLR users: Ideal for everyday shooting, travel photography, and family events. The 512GB capacity means you can shoot for days without swapping cards. Full HD videographers: U1 and Class 10 ratings ensure reliable 1080p recording. Suitable for interviews, vlogs, and event coverage where long recording times are needed. * Frequent data movers: The 150MB/s read speed significantly reduces transfer times when offloading footage to a computer via a compatible UHS-I reader. For professional 4K video work or high-speed burst shooting, consider UHS-II or V60/V90 rated cards instead.

Things to Consider

The advertised 150MB/s read speed is achieved through SanDisk's proprietary technology and requires a compatible UHS-I host device and reader. Without such hardware, performance is limited to standard UHS-I speeds (up to 104MB/s). Write speeds are not officially published and are typically lower than read speeds. This card does not support 4K or 8K video recording. The 512GB capacity is calculated using 1GB = 1 billion bytes; actual usable storage is slightly less due to file system overhead. Some older camera models may not support SDXC cards larger than 32GB or 64GB. ## FAQ
Q: Can this SD card record 4K video? A: No, it is designed for Full HD (1080p) recording. For 4K video, choose a card with UHS Speed Class 3 (U3) or V30 rating. Q: What file system should I use? A: The card comes pre-formatted in exFAT, which is compatible with most cameras and computers. For best reliability, format the card in your camera rather than on a PC. Q: How do I achieve the 150MB/s read speed? A: Use a SanDisk SD UHS-I card reader (sold separately) connected to a USB 3.0 or higher port on your computer. Reading directly from a camera will be limited by the camera's interface speed.
