SanDisk Ultra 128GB SDXC UHS140mb

If this product exists, it would likely be an upgraded version of the SanDisk Ultra SDXC cards, offering a larger storage capacity of 128GB and a read speed of up to 140 megabytes per second (MB/s). Here’s what you might expect from such a card:

1. 
   Capacity: A storage capacity of 128GB, which provides ample space for storing photos, videos, and other files.
2. Speed Class and Rating: The “UHS-I” in SDXC UHS-I stands for Ultra High Speed Class 1, which is designed to support data transfer speeds of up to 104MB/s. The “140mb” in the name suggests a read speed of 140 megabits per second (Mbps), which translates to approximately 17.5MB/s.
3. Performance: A read speed of 140MB/s would indicate a fairly fast data transfer rate for reading data from the card. However, it’s important to note that write speeds are often slower than read speeds on memory cards, so if you plan to use this card for high-definition video recording or burst photography, you should also check the card’s write speed specifications.
4. Compatibility: The card should work in devices that support the SDXC standard, which is common in many digital cameras, camcorders, laptops, and other devices.
5. File Format: Depending on the capacity and the manufacturer’s choices, the card might use the FAT32 or exFAT file system to ensure compatibility across a wide range of devices.
