Question

What FileSystm& AllocationUnitSize is best 4a 32Gb USB Drive

Sep 9, 2015 4:30PM PDT

I have a 32GB Lexar JumpDrive M10 - Secure USB 3.0 (The company claims it has speeds of up to 100MB/s read, 30MB/s w/ USB 3.0) writeand the average file size I have sent to it is about 157.50MB am wondering what the fastest file system for it is. Also, is it worth it to for me to make it's Allocation unit size to the highest possible at the expense of the space .

Answer
FAT32 is very much standard for 32 GB drives.

I've seen folks having compatibility problems when they format anything else. If you need something faster, go for an external USB3 hard drive.

Good luck.

Ok but is it worth it to use its max allocation unit size?

I thought that NTFS was the most stable... I guess I'm wrong. I also liked the fact that you could compress files but that slows things down anyways and isn't available in the higher allocation unit sizes anyways. But will the highest allocation size give me a speed boost worthy of the storage decrease? Again my files are 157.5 MB on average? (Also I don't have that many files per folder.)

Now that's a nice subject for an experiment.

Make some files of, say, 1, 2.5, 10, 25, 100, 250, 1000 MB.
Then find the time needed to copy those files to the stick, after formatting it with different allocation unit sizes.

Can you tell the results of your experiments? It would be intesting to read.
