Hi, I’ve bought a SanDisk Ultra (256GB) as second storage for my Surface 4, the default format is exFAT but I’ve read that NTFS is much better on Windows, I will not eject it or use it on another device, should I format it to NTFS? will it cause any harm or decrease the life of the microSD card?
Please be informed that formatting the device as NTFS will make it unwriteable on a Mac computer. Most Mac computers can read NTFS, but not write.
NTFS is a journaled file system, this creates more read/write activities. Therefore, it MAY decrease life expectancy of your device.
Once the device is formatted as NTFS, you MUST use “Safely Remove Hardware” to remove your device.
