If you are benchmarking with AS-SSD or CrystalDiskMark then you are getting 98.7% of advertised Reads and 49.6% of advertised Writes.

The advertised 450MB/s Read/Write speeds are with ATTO.

Don't know what to tell you about your low Write speeds; double-check that you are connected to port SATA6G_1. If it is already there then try SATA6G_2.
See page 1-28 of your motherboard manual for the location of the ports.

Thanks for the clarification I emailed Kingston and they said,, Please note that the advertised Speed is based on ATTO compressible Benchmark test and your test result seem like AS SSD Result using incompressible test data.

Please see below for advertised speed for compressible and incompressible: with a link to their site where it explained further, I ran another bench using ATTO and all looks good I'm actually getting faster read speeds then advertised, thanks for helping me :)
