Ever since I have used Truecrypt & Verycrypt I have had severely poor write performance on all my encrypted drives, at the time I assumed it was the old server I was using, which did not have hardware AES. (Q9550)
I have just upgraded it to a Skylake 6700 on a Q170 mb and I still have the same issues, I have tried Windows 2008r2 and Windows2012 r2.
This happens on the onboard controller and the LSI 9211 & the 9207 controller I have just purchased in case the other 9211 was at fault. I have even tried connecting the disks to a VM and it still impact the performance, but I have never seen anyone else report a similar impact!
The disks I have used are WD Green and Red 2, 4 & 6TB disks, which all perform perfectly prior to being encrypted.
I have run some benchmarks to show the difference, and the sequential transfer is equal to copying large files. It takes days to populate a 4TB hard disk.
Unencrypted WD Red 4TB on LSI9207 controller
Encrypted WD Red 4TB in lsi9207
These is the benchmark to prove AES is enabled.
And here are the settings for the encrypted volume
Has anyone else had a similar problem, I must have ruled out hardware as drives and motherboard / CPU have all been changed. So there either must be something I am doing wrong or this is normal for TC / VC. I have tried formatting the drives with different cluster sizes, and have tried whole disk and container volumes, the speed is always impacted like this.
Various versions of truecrypt and Veracrypt 1 - 1.17
