Core i5 760
ASUS P7P55D-E LX mobo
Windows 10 Home (x64)
Long story short, old SSD died on me. Had it running in same exact system with write speeds @ 700+ MB/sec. (SATA III) That was on Windows 7 though, with the correct drivers from Marvell.
I bought a new SSD (Samsung 850 EVO 500GB), it is only running at 3Gb/sec speeds, @ about 375 MB/sec.
I am thinking that even tho these Marvell 91XX drivers for Win10 installed and are displaying in Device Mgr correctly , they are not working properly and that's why I am stuck at SATAII speeds.
My BIOS indicates the new drive should be operating at 6Gb/sec, as well as Samsung's (useless) SSD software.
The exact name if the Marvell controller I have is "Marvell 88SE91xx Adapter".
Any thoughts or ideas are greatly appreciated. If I can't get the drive up to speed, I will either go back to Win7 or just live with the drive at half the speed it should/could be.
