Silicon Motion SM2246EN SSD Controller Preview - Benchmarks - AIDA64 Random Access Time

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.

AIDA64 Random Access Time


Version and / or Patch Used: 1.60

AIDA64 offers several different benchmarks for testing and optimizing your system or network. The Random Access test is one of very few if not only that will measure hard drives random access times in hundredths of milliseconds as oppose to tens of milliseconds.


Drives with only one or two tests displayed in the write test mean that they have failed the test and their Maximum and possibly their Average Scores were very high after the cache fills. This usually happens only with controllers manufactured by Jmicron.

The reference design uses pretty much the best NAND on the market today, so the latency will be low. The real test for this controller will come when paired with TLC NAND.

I wish we had this controller paired with IMFT 20nm NAND flash since the IMFT 20nm is what gives other controllers problems with write latency.
