ADATA SX300 256GB mSATA SSD Review - Benchmarks - Power Testing

ADATA SX300 256GB mSATA SSD Review
Today we did deep and take a close look at ADATA's SX300 256GB mSATA SSD. It uses new IMFT 20nm flash, but is that a good thing?

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 battery life test many actually be a result of ADATA's design. If you read our Samsung 840 EVO review then you know we damaged our battery in the Lenovo W530. The ADATA SX300 is the drive we had testing when I had to run to the airport for a weeklong trip to Korea. The battery was fine during the test, but we left it drained for a week without a charge. The test completes when the battery dies and the system has an ungraceful shutdown. I wanted to mention this for the readers who look at every SSD review we publish. The battery was fine during this test.

 

That said, the battery was fine, but the SX300 wasn't. The LSI SandForce B02 controller normally pulls less power than the normal SF-2281 controller. The 20nm flash should also use less power than the older 25nm, we proved that theory with the Intel 335 240GB review.

 

Other components, like the VRMs (voltage regulators) and other surface mount components that we normally overlook take power as well. If a company uses components that are not as efficient as others, it shows up in this test.

Here we look at power consumption under a microscope. The ADATA SX300 has a low idle, but pulls a lot of data when reading and writing. On the chart you can also see where tests start and stop.

 

A slower SSD will start later in the tests (there are 8 total) on the chart. If a test takes longer, then the drive is in use longer. That means it consumes more power to finish a task. We call this "time in use busy time", and busy time means power consumption time.
