Samsung 840 series 250GB Firmware Update: DXT08B0Q Benchmarks

Samsung released a new firmware for the Samsung 840 series (Pro and non-Pro both) few days ago. I didn’t upgrade that instant, because I saw on OCN forums that few people were having issues with the new firmware. I don’t want to end up with a dead drive. I don’t have a spare SSD lying around. Wish I kept that old SSD with me just in case something went wrong with the new one. But I didn’t and there is no point regretting about it. Have to move on.

But today I gave in, and went ahead with the update. What made me confident that something bad might not happen is because Samsung hadn’t pulled the firmware. That means there is nothing wrong with it to begin with. The people who got bad outcomes must have done something stupid. Just to be safe, I killed all the apps running in the foreground as well as background before starting the firmware update process.

I had DXT07B0Q firmware before update. You have to use Samsung SSD Magician software to do the firmware update. Even without me checking for an update manually, it automatically detected that there was a newer firmware available and highlighted in the UI of the software. Nothing amazing. That’s the way everything should work these days anyways. Just wanted to say that it is working as if should.


Everything went smooth. It didn’t take long, and once done, the software told me that it needs to shutdown the PC to finish the update. What I didn’t know was that it would not automatically reboot. It was a clean shutdown, not a reboot. Some people might be confused by how it happened. With the previous drive, all that was required was a reboot. Anyways, now I know how it works in the future.

So did I see any gains with the new firmware? No! None at all. I recorded some benchmark scores on AS-SSD before and after the firmware update. Before running the test, I optimized the drive using the Magician software. Here are the results.

Note: Both tests were run with Intel Rapid Storage Technology ver. drivers.

Before update ( ver. DXT07B0Q )

After update ( ver. DXT08B0Q )

As you can see, the scores are identical. The difference would be attributed to measurement error. Well, at least the performance didn’t go down. That’s a relief.
