Hi,

This is my first post!  :-)

I purchased a SanDisk Ultra 64 GB MicroSDXC UHS-I Memory Card to use in my Samsung Galaxy S5 phone:

https://www.amazon.co.uk/SanDisk-Ultra-MicroSDXC-Memory-Adapter/dp/B013UDL58E

I plan on using this for data storage, and to access on my PC using a USB 2 cable.  The card is pre-formatted as exFAT:

https://kb.sandisk.com/app/answers/detail/a_id/312/~/formatting-a-memory-card%2C-flash-drive-or-device-using-a-pc

With this in mind, just a couple of quick questions:

1) Are there any advantages/disadvantages of formatting the card using the phone's format option, or just use "as is"?

2) If I use the phone's format option on the card, what format will the card be formatted in?  Will it still use exFAT, or some other format (FAT32, ext4, NTFS etc.)?

Thanks.

I should add that my phone runs Android 6.0.1 (Marshmallow).

All I can tell you is that I have never formatted a microSD card for any Android device since they're ready to use "out of the wrapping".

 

I would presume that the format is something that Windows recognizes as well, since they can be used "out of the wrapping" on a Windows system as well.  The MicroSD card in my PC at the moment is formatted FAT32.

 

Addendum:  The 32GB card that I just popped out of my S7 is FAT32 as well.

Thanks for your reply.  I decided to just use the SD card as it is (without formatting myself) - everything has been working fine.  Also, when connecting the phone/SD card to the PC for data transfer, MTP (Media Transfer Protocol) is used - so the PC does not actually know what file system is being used.

You're welcome.

 

One thing I can tell you is that if you have massive quantities of data to transfer to the card it is much faster to use a micro-to-standard SD adapter and put the card directly in the SD card slot on the computer.  It's almost impossible to describe how much faster when you're transferring hundreds or thousands of MP3 files at one time.

 

Virtually every phone I've owned has some warning or another about not transferring music, photos, etc., directly to the card (or from the card) using the computer.  I have ignored this for years with absolutely no ill effect.  Logic dictates this cannot matter.  An MP3 file is an MP3 file on any medium it's stored on no matter how it got there and if the card is accessible by Android and by Windows then both can work with the file system that the card came formatted with.

Thanks for those tips.  My PC does not have an SD card slot, so I'm using the USB cable, which works fine.  In my case I am only likely to be transferring a small number of files occasionally.
