- After the SecureErase (I booted to linux and used hdparm instead of the gui tool as I couldn’t see my flash drive. See this page https://blog.oxplot.com/make-usb-flash-write-fast-again/ on what commands to use.) the drive no longer has a filesystem so I formatted it back to NTFS 4K cluster size using Windows 10.
Its abit overcomplicated, why u use linux commands when u already secure erased your drive with partedmagic?
I did a secure erase with parted magic like you too, after that i formated my stick with SDFormatter with these options.
Format Type: Quick
Format Size Adjustment: On
Thats it my speed went up again.
The good thing about SDFormatter is he sets the correct alignment automaticly, u can check that with AS SSD Benchmark tool (see screenshot) if there is ok you are good, if there is BAD you are i guess u know it 
so i think the stick loses speed if there is a wrong alignment.
