We used a Dell Latitude D630 notebook, which is based on Intel’s Santa Rosa platform and the latest Core 2 Duo T9000 series CPU (45 nm Penryn). Using a 9-cell battery, this is an excellent example of a business notebook that can run for several hours. Interestingly, the battery runtime test results varied by as much as one hour with the flash SSDs. While all low-level performance tests were conducted on our storage reference system (above), the battery tests and Mobilemark was executed on Windows Vista Ultimate.
