64 Gb Micro Sd Card

I am going to Format my 64 GB SD Card to ExFAT for my Tablet.

I wanted to use the smallest Cluster Size but I wanted to know what can I pick?

Should I pick 128kb or 64kb?

I can go down to 4kb.

 

It depends on what it's used for. Larger sectors can increase read performance, while smaller clusters maximize usable storage space.

Will this be for apps or data? Will you be storing large files like movies?

 

It is a 64 GB SD Card and will be use to hold Full Vieo Files.
Then they will be Played Back.

It will be use on my Tablet and I thought you use the Smallest Cluster Size to get more useable space from the Card?

Can you help?
Thanks.

 

Larger clusters can increase read performance, while smaller clusters maximize usable storage space.

 

I do get how Larger Cluster Size speeds up Read Time.

And how Smaller Cluster Size will let you get as mutch space as you can.

So should I use 4kB or 128 kB Cluster on a 64 GB Card for Video Play Back?

 

You're storing movies, which will most likely be larger files. I would guess that small clusters won't make a major difference in the amount of movie files you'll store on the card. However, faster read times are a benefit when watching those movies.

 

This what I thought you want a good Read Speed when Play Back.

So would you go with 64kB or 128kB or 256 kB?

 

I would start with 64.
