MobileMark 2012 1.5 is an application-based benchmark that reflects usage patterns of business users in the areas of office productivity, media creation and media consumption. Unlike benchmarks that only measure battery life, MobileMark 2012 measures battery life and performance simultaneously, showing how well a system design addresses the inherent tradeoffs between performance and power management.
The power charts are starting to get a little difficult to single out an individual drive so we're isolates a couple of models below.
The SanDisk Ultra Plus delivered the third best score we've measured to date in the 240-512GB capacity size. The Crucial m4 and Samsung 840 give a little more battery life, but the Ultra Plus did much better than any of the LSI SandForce drives on the market today.
PCMark Vantage HDD Test - Power Draw
Looking at a test during a run in PCMark Vantage we see how the Ultra Plus performs so well. The idle power is a little higher than the Samsung 840, but much less than the Intel 520. The Ultra Plus uses less power when reading back data from the drive. The peaks are random date writes and the Ultra Plus manages to draw less power in nearly all of the spikes than the 840, the Intel 520 does a little better when writing random data.
If you are reading data back at a constant rate while on battery power, the Ultra Plus will actually give you more battery life than the Samsung 840.
