hi just installed fresh win 7 on first ssd (yep Ive been stuck down a well)
however im not sure im seeing the speeds I should be boot times etc.
I included a snip of crystal disk info/mark and dev manager
did try to set AHCI in bios prior to win 7 install (greyed out) also tried since AHCI remains greyed out
and here is AS SSD results
Please edit your profile with ALL your hardware specs.
You have two devices that can explain the low transfer rates:
- The SSD itself
- The SATA channel.
On post 1, on the picture, Disk Info: transfer mode = SATA/150 ! SATA/600.
If you put the mouse over it says: Current mode ! Supported mode.
In other words your SSD can work on SATA 600 but is working on SATA 150.
That's why your SSD is working with so low transfer rates.
As I don't have your hardware specs, can't help you more.

hi sorry about that here are some snips from speccy
I have also checked in regedit msahci start value is zero and pciide start is set to value 3
also checked trim is enabled and it is.
Speccy shows max transfer mode = SATA III - 600 and used transfer mode = SATA I -150.
Is the SSD connected to SATA 0 on MoBo?
As you have an old system, does disk operation set to IDE on MoBo?
hi thanks again for your help
however I am unsure of the exact sata location of the ssd but is installed in only slot/bay for storage (mini pc). crystal disk mark shows msahci as ok so assumed was running in ahci ?
NVIDIA's MCP7A chipset has only SATA II (3.0 G/s) so you'll never reach the 6.0 G/s. DailyTech - NVIDIA MCP7A Chipset Details Revealed
But you are working on as SATA I, and it's probably because on BIOS your drive is set to IDE mode.
To install under SATA you will need to set to SATA (and may have to load the NVIDIA's MCP7A drivers during win 7 installation)
Hi thanks again for your help.
So technically could be made a little faster? Would the improvement be significant?
If yes is it a difficult process?
Thanks again
Could i potentially see faster speed by installing the boot disk into a external bay through usb 2.0
