I have a Samsung SSD 850 EVO 4TB and under Linux I'm only getting
~240MB/s write speed. On Windows it's 490MB/s (yes, without cache).
The read speed is the same on both Linux and Windows, though. Both are
512MB/s.

	Just curious: are you using the "deadline" scheduler? What file
system? Ext4?

Yes, the deadline scheduler.

On Linux I'm writing directly to /dev/sda, no file system.

Regards,

Bram
