Phoronix takes a look at the Intel Atom Disk Encryption Performance under Ubuntu Linux

While the ASUS Eee PC 901 doesn't have its solid-state disk drives encrypted by default, if you are storing any potentially sensitive information on this netbook -- or any mobile device for that matter -- you really should encrypt the data. When you lose a mobile device or it has been stolen, it can be a nightmare if your banking information was stored on there or even just passwords to your Internet accounts. However, what is theperformance cost for fully encrypting a hard drive on one of these Intel Atom computers? In this article we are looking at the performance impact of fully encrypting the solid-state storage versus an unencrypted LVM within Ubuntu Linux.
