Bought a WD green 223Gb M.2 SSD (sandisk controller and NAND) for use on a external enclosure and have a (massive) problem of 30Mb/s write, 45Mb/s read speeds, i would like to have the SSD's normal speed.

-Empty new SSD, NTFS formatted with 4kb block size
-SSD firmware version: UJ450000
-ASM1153E firmare version: 140509A18200 (checked using factory production tool "MPTool")

What i have tried:

-Changing from exFAT to NTFS and changing block size in both
-Using back panel mainboard USB3.0 connectors (it crashes if using USB 2.0 connector due to lack of power delivery)
-Check firmware versions (both seem the most recent)
-Add a little bit of solder on one of the USB3.0 connector SMD pins since it looked like it didn't have any
