If I had x capacity/amount in files, how much free usb drive should I have left for a optimal running flash drive.?
How much free space should I leave on the usb flash drive for it to work optimally...or 2 say it another way. How full can I have my flash drive before I notice a change in performance?
Update:Truth be told, I was given the green light to purchase a multipack of flash drives (like 2 thumb drives). I plan on keeping one and the other goes to the purcahser. So, in essence, Im asking so I can pick a max capacity value based on the answers I receive. Since I am the "tech" guy and Computer fixer in my household, I'd like to buy the drive with a good amount of space.

The USB falsh drive will work at it's normal speed, until you get to 100% full, Then write operations will stop. The drive will still read at full speed, just not write any new files.
If you get your Hard Disk almost completely full, then you start getting problems with disk fragmentation. The mechanical drive has to hunt around to find the last few free sectors to write files to, and then when reading them back it has to hunt them out again (bad disk fragmentation) So the computer seems to run slower because of this.
But with modern large disks and automatic disk defragmenting in new versions of Windows, that's only an issues when you get to the last few % of disk space. And is no problem with random data files on a solid state disk and there is no head movement or mechanical latency to worry about. A flash memory chip can read 100 random blocks as quick as it can read 100 contiguous ones.
well I think its true to say that sdcard(USB) storage is NOT optimised for PERFORMANCE so your question isn't really answerable. performance might not be affected by how much space is left either. You might be able to implement a cache to help it.
It doesn't work that way. I believe due to the much faster access times from the SSD free space is irrelevant
