That has not been my experience at all. I have personally encrypted two machines that had SSD drives, both had modern CPUS, one was an I3 and one an I7. There was a substantially noticeable decrease in performance using TrueCrypt. In fact, the wait times increased so much after encrypting that I grew impatient waiting for boot times and Microsoft Office load times.
This article has some scientific testing regarding performance on SSD drives that are encrypted: http://media-addicted.de/ssd-and-truecrypt-durability-and-performance-issues/744/ On Tue, Jan 3, 2012 at 12:07 PM, Edward Ned Harvey <[email protected]>wrote: > > From: [email protected] [mailto:discuss- > > [email protected]] On Behalf Of Chris O'Connell > > > > ALSO, NO FULL DISK ENCRYPTION should ever be used on an SSD drive. > > Performance will drop by 30% and the drive's wear-leveling system and > > TRIM > > won't function correctly. > > First of all, the supposed 30% performance hit takes you down from 200% to > 170% performance as compared to an HDD (or whatever arbitrary numbers we > want to make up for comparing HDD vs SSD performance where SSD performance > > > HDD performance). > > Second of all, some OSes support TRIM on encrypted drives.
