Samsung 840 250GB SSD Review - Benchmarks - Test System Setup and ATTO Baseline Performance

Samsung's 840 returns for the second day in a row. This time Chris tests TLC flash paired with a tri-core MDX controller with the 250GB model. Will he love the low power or will the 240MB/s sequential write limit send him for a cold shower?

Lenovo W530 - Mobile Workstation

 

 

We use two systems for SSD testing. The desktop runs a majority of the tests and the Lenovo W530 runs the notebook power tests as well as the real-world file transfer benchmark.

 

 

ATTO Baseline Performance

 

Version and / or Patch Used: 2.34

 

ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.

In ATTO where we test maximum performance with a queue depth of 4 we measured reads at just over 560MB/s. This is a very good rating and one of the highest we're recorded to date.

 

The write speed of the 840 250GB was nearly 260MB/s. The low write speed may become an issue further in the review when we get to the real-world tests.?
