Cloning via bootable CD and SATA III

Thread needs solution

I am currently using ATI2015 and created a bootable rescue CD.  It only images at SATA II speeds yet the hardware and HDDs are SATA III (3) (6G).  If I purchase ATI 2017 does the rescue CD support SATA III (3) (6G) controllers?

Hello TIP32a,

Welcome to Acronis Forums!

2015 version supported both SATAII and III. There are commands to check how the SATA connection was initialized in the bootable environment. Press Ctrl+Shift+F2 in Acronis program to enter the command line and run these commands:

dmesg | grep -i sata | grep 'link up'

dmesg | grep -i ahci | grep -i Gbps

The output should show the maximum possible speed for the SATA connection.

As you have said, SATA II speed is 3 Gbps or 300 MBps

SATA III (6 Gbps) or 600 MBps

Are you sure that the bottleneck is in the cloning software and not in the setup/environment? Maybe run a benchmark with tools like CrystalDiskMark (while you are in Windows) to verify the real read-write speeds that your hardware/configuration can provide? I suppose you have some fast PCIe-connected SSD disks to expect SATAIII's near 6 Gigabits per second? I assume you are fully aware that regular HDD cannot get close to even half of the maximum SATAII speed, not to mention the SATAIII. I am saying that because you've mentioned "HDD" which confused me.

If you are sure that the problem is in Acronis bootable media (which is Linux-based) not allowing to reach SATAIII speeds, you can try creating a custom WinPE-based bootable media with 2015 version and add drivers for the disk controllers. See https://forum.acronis.com/forum/100770 for instructions. It references ADK 5 for Windows 8.1 which is better for Acronis True Image 2015, compared to the latest Windows 10 ADK.

SATA speeds are dependent upon the hardware as well. If you have a SATA card that is PCI 3.0, but shares bandwidth of the ports and you have 2 ports in action, you can theoretically cut the performance in half on both drives as they each will use half of what's available.

Also, the default Linux drivers may not be optimized for all types of hardware.  You can also try WinPE rescue media and provide specific drivers for your system to help ensure it is using the most compatible and current Windows drivers to ensure the best functionality and performance.  The default Linux media is convenient, but because it is Linux based (and drivers are not regularly updated as well), WinPE rescue media can have an advantage in driver support and possibly performance as a result.
