Thread: Solid-state drive + Complete Disk Encryption = Slow as hard disk drive

The desktop was function unencrypted, the laptop tries were function with complete disk encryption. The result on the desktop system was fairly much as looked, read velocities for the solid-state drive were ever superior, just when write velocities were tried, sequential write velocities, the hard disk drive won. Random I/O the SSD crushes the competition.

On the laptop, were the solid-state drive was supposed to furnish a sweet function boost, things were less promoting. Without encryption the solid-state drive acted as seen in our SSD vs HDD film here

When the drive was encrypted though... what a dissimilarity... the write velocities dropped horribly, the read velocities were a far cry from what to look. In short, with encryption changed I did not observe a difference among the SSD and



HDD laptop. Benchmark utility were limited in their efficiency as the encryption driver is rather low level, read tries were not possible, just ATTO functioned "a bit" turning in 30-35Mbs/ read velocities on the SSD. Write velocities were measurable through utilizing FC-try and making the dissimilar document patterns, the answers:

On the desktop workstation I was capable to function HD Tune; To insert additional stress on the I/O I established 4 sessions of HD Tune Read velocity at the similar time, the solid-state drive entirely ruins the HDD here:

Unluckily on the laptop system with Utimaco Safeguard function is also same to a common HDD to excuse the costly memory. Most probably the Utimaco software will have to be patched/tweaked for SSD use to assume advantage of its function, recently entire read/write actions pass by the encryption driver, causing the bottleneck, and it is not central processing unit bound either, it never goes over 10% throughout heavy document transfers...

Was rather saddened to see these answers. So be warned if you have complete disk encryption and need to invest in solid-state drive. What DOES function excellent is an encrypted volume for your DATA yet, utilizing truecrypt or same, leaving the OS/Apps unencrypted on the solid-state drive. But that was no choice for me.
