Hi,
Just I've updated my M14x R2 Bios to the latest one A14 from Dell Support site because I wanted to install Windows 8.1 and that Bios was recommended. After the update my disks just slowed down (mSata SSD + 500GB WD Black). If I'm checking the disks speed in Inter RST just shows SATA transfer rate: 3Gb/s instead of 6Gb/s (which was before). If I'm changing the SATA operation from RAID to AHCI just worst.
It's a different story that I had lots of problems and spent hours with install Win8.1 while I found the correct settings in the BIOS. But the disk are still slow.
Could you plaese advise?
Thanks in advance
