Kingston A400 SSD performing poorly?

[troy1960]

I'm only getting around 350 ish megabytes per second read AND write while the internet says it has to do 500 read 450 write.. Yes im in AHCI mode, ive checked multiple times.. What do i need to do? my friend is hitting 450-500 read on his A400. We both have the 120GB model.

If your A400 is connected to port SATA3 or port SATA4 on your motherboard, then connect it to port SATA1 or port SATA2.

Ports SATA3 & SATA4 are run by the ASMedia ASM 1061 chipset, which has a bandwidth of PCIE x1.
Ports SATA1 & SATA2 are run by the AMD B350 chipset, which has a larger data bandwidth.

Page 29 of your motherboard manual will show you the location of the port.

Found it using the MSI Board explorer in the bios. Thanks! it was indeed plugged into port 3, moved it to port 1 and its pulling 550mb/s read and 400 write.
