Unsolvable Sata Problem

[Aokiji]

Hey guys

 

have recently noticed that my second pc has become so slow that what it used to be and have narrowed it down to my sata being nerfed and with this i mean its not performing to maximum potential

 

my sata mode in bios is on AHCI mode and Hard drives active mode is on MWDMA2..

so i changd my sata mode to enhanced IDE with drives then running on UDMA5 mode and the speed and performance is exactly the same as MWDMA2

even went as far installing a pcie sata controller card and booted windows from that with drives running on UDMA6 mode and still no change in performance what so ever

 

the hard drive active time stays on 100% until fully booted after a few minutes it wil go back to normal % but during this period the read speed is between 3mbs to 5mbs

i have now tried everything new OS and still the same cant crack this problem

 

the actual AIDA64 Read Suite runs perfect with performance at expected levels

it was working fin before up until now

 

OS is windows 10

Asus P5E Deluxe  ( Rampage Formula Bios Mod)

Intel Q9505

Have you tried another cable?

 

Also it depends on what requests are given to the hard drive. If the OS is pounding the drive with lots of requests, storage performance chokes no matter what kind it is. Seeing how you say AID64 runs are fine, I suspect this is what's going on.

Maybe I'm starting from too a basic level, but if performance decreased over time: is it (de)fragmented (assuming it's an HDD)? Or with "installing new OS" you mean you wiped that drive and started from zero (I assumed you boot from a different drive)?

the common denominator here is the HDD.

 

when you say maximum potential, what are you expecting, vs what are you achieving?

yes have tried another cable still does the same , the OS boots extremely slow an does things slow but anything else works like it should in terms of load speed etc

how can i see what is bombarding the drive with requests the event viewer does not tell me much

did also drive other drives basically does the same

 

now i can format my system again how ever before i do want to rule out any other possible cuases

You can use Resource Manager (there's a link to it from Task Manager under the Performance tab)
