I bought a new external ssd to use for data storage (mostly Logic projects and music files) and for some reason the same files seem to take up more space on the ssd than they do on my old conventional hard disk.
For example my Logic data folder takes up around 60 Gb on the old hard drive, but when I copy it to the ssd, it shows around 65 Gb used.
The 250 Gb ssd showed as full and would not allow me to copy any more data when I had put around 170 Gb on it from the old disk, so the amount of missing space expands as the amount of actual data goes up...
Note it is not a bootable drive, so I would not expect large hidden system files; nevertheless I tried showing hidden files, and while it did reveal some, they were only a few Mb, and nothing like the discrepancy in capacity.
Other relevant information: Mac OS 10.7.5 (this is the most up to date OS I can run on my ancient Mac)
The new SSD is a Samsung T3, I have not reformatted it and left it in the default exFAT format.
Any ideas?

I suspect its due to sector size though.

And technically SSDs don't have sector sizes, because of the whole not having sectors...
But other than that...
I would look to re-format though and try again... maybe try a more mac specific file system
I left it in the default exFAT format because I read elsewhere that this format would give better performwnce as it is optimised for solid state storage (and would also allow compatibility with Windows and Android.
Just to clarify, I bought the drive new, and the total formatted capacity is showing as 250 GB as expected, it's just the used space that is showing as higher than expected from the size 0f the data.
