Silicon Motion SM2246EN SSD Controller Preview - Benchmarks - Test System Setup and ATTO Baseline Performance

Silicon Motion SM2246EN SSD Controller Preview

Silicon Motion is looking to take a large portion of LSI SandForce and Marvell's market share with a new 4-channel SSD controller. Let's take a look.

Desktop Test System

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 test 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.

Our ATTO sequential read scores were much better than Silicon Motion's claim of 540 MB/s. We managed to hit nearly 562 MB/s. SilMo claims 410 MB/s sequential write speeds, but we managed to just break 307 MB/s with the reference board and what we suspect is early release firmware.
