the file size should not be different even to the extent of 3 time larger. Something is not right. How are you copying the files? Are the files compressed on the HDD?

One thing I forgot to mention was that I chose 512 byte cluster size because of the small size of the most of the files I am storing on the drive. You'll get better performance with a larger cluster size which would be better for media files like large video files at the cost of losing some file space. Not as much as the default Sandisk cluster size. As you can tell I'm not an expert but it worked for me.

I Windows Explorer, right-clicking a file or folder and choosing Properties will show the nominal size as well as the disk size.
I believe a cluster size / allocation unit of e.g. 1024 KB mens all files will take up at least this much space on disk each (and e.g. a file of nominal size 1025 KB will take up 2048 KB, disk size). So a file of 1 byte (0.001 KB, extreme lower limit) will take up about a million times as much space on disk (extreme upper limit). A short Word document of e.g. 20 KB will take up 50 times as much; a medium resolution photo of e.g. 200 KB will take up 5 times as much.
I suppose a large allocation unit leads to better speed performance for large files, so the best choice of allocation unit is a compromise. Perhaps there are also design choices made when building an SSD that mean it will work best with a certain allocation unit - I do not know.
I suppose the only way to change the allocation unit is through formatting the drive, so I suppose you'll need some other place to keep your files meanwhile.

External SSDs come in small packages that are easy to take with you, offering the best combination of portability and performance. And they’re more durable than external hard drives because there are no moving parts. But they’re far more expensive, so use them for your working files where speed is critical Krogerfeedback

I had the same problem and reformatted to NTFS and it fixed it. Is there any difference in performance between exFAT and NTFS? Could the cluster size change to speed of transfer?
