Windows 10: Slow SATA Speed On Windows 10

Hi,

Just last week I upgraded my computer from an Intel i5 2500 that was on the ASUS P8 B75 board with USB 3.0 to an Intel i5 6500 on the MSI Z170A Tomahawk AC with USB 3.1.

The issue I am now having is that my read speeds from any sata drive is super slow, about 10MBPS, however copying from USB 3 to USB 3 works fine, I get about 100MBPS average.

I have clean installed Windows 10 numerous times, however when I did a clean install of Windows 7 everything works fine and fast. I have even went to the device manager and changed each sata drive policy but that did not work.

I have no idea what the problem is and microsoft always gives some stupid answer that never works.

Thanks.

:)

 

Copy speed very slow in windows 10

Using NAS Network mirror drive SATA to NEW USB3 thumb drive.

If downloading from the 120 MB Internet to the NAS, speed is constant.

PC SATA to NAS, speed is high.

The USB 3 starts out high, then drops off.

You might look at:

Windows 10 may have added this API (see step 3 here)

making a USB hard drive my primary hard drive

The internal SATA connection is significantly faster than USB read/write speeds. I'm no expert so I can't say how this would slow down the OS.

 

If you have Intel Rapid Storage Driver installed , uninstall it, reboot and see.

 

Is you BIOS set to AHCI or IDE?

 

I did not have this installed so I installed it thinking it would help make the drives faster but it never, so I just uninstalled it thereafter.

 

I downloaded the lastest BIOS update for the board and it is set to AHCI.

 

I'm baff right now too, I took a look at the MOBOs page and it should be tearing up the data:
• 6 x SATA 6Gb/s ports*
• 1 x M.2 Key M Socket supports type 2280/2260/2242 storage devices in both PCIE Gen3 x4 & SATA mode
- Supports PCIe 3.0 x4 and SATA 6Gb/s standards,4.2cm/ 6cm/ 8cm length M.2 SSD cards
- Supports PCIe 3.0 x4 NVMe Mini-SAS SSD with Turbo U.2 Host Card***
• Supports RAID 0, RAID 1, RAID 5 and RAID 10 for SATA storage devices

 

Exactly, everything works fine on windows 7 though, I am just as baffed as you are. Windows 10 is supposed to be much more advanced.

 

Then type this in an elevated prompt and post here a screen shot:

Do the same for the "poor perfoming" drive

 

I finally found a solution on this forum, I followed this guys steps below and now getting full drive speed.

really the most frustrating thing I have ever encountered on a pc that took me over 2 weeks to find. Just upgraded back to windows 10 and followed the link, getting about 200MBPS from my sata 6 to my usb 3 drive *Smile

 

Good to here Kats*Thumbs
Keep us posted, please.
At least I'm interested.

 

i most definitely will *Smile

 

Also I found that after installing the utilities from MSi disc it caused havoc with the speeds, so I had to uninstall all the crap utilities that came with the disc and speeds went back to normal.

 

Interesting to hear.
I'll keep an eye on it.

I should be getting my new PC this week and it has the Z170A PC MATE board.
It comes with a 512 M.2 SSD, and I'm installing/moving my 512GB Samsung 850Pro and 1TB Samsung EVO to it.
