Restoring drive from Marvell SE9128 SATA controller extremely slow (with solution)

I had a drive failure recently. I put in a new drive, booted to TrueImage, and initiated a restore of that drive from my backup. However, going through the restore setup screens took a long time, and once it got going, it reported that it would take an estimated TWO DAYS to perform the restore. This drive had about 300 Gb of data on it, and the full drive image takes only about 45 minutes when the backup runs within Windows.

I fought with this for HOURS, assuming I was doing something wrong. I was about to give up completely and swear off TrueImage forever when I tried something random: I unplugged my backup drive from the Marvell SE9128 SATA port on my motherboard and plugged it into one of the Intel PCH SATA ports, and rebooted into TrueImage. This time the restore worked as expected, taking about 1.5 hours.

I don't understand why TrueImage would treat this Marvell SATA controller so vastly different than the Intel controller. But they REALLY need to come up with a way to either detect this and say something about it in the UI before the restore, or add a knowledge base article about this with keywords like "slow restore". I wasted over SIX HOURS trying to get this to work and I was literally about to bite the bullet, let the restore run for two days, and then immediately delete TrueImage and install Ghost.

I hope this might help others who have a similar issue in the future, and hope that Acronis will do something about this or at least make this very obvious to their customers.
