Intel Rapid Storage Technology 12.5 is faster than 11.7

Remember I recently upgraded the firmware on my Samsung 840 series 250GB SSD? Even though the release notes said that I would see some performance improvements with the DXT08B0Q firmware, I didn’t see any. Then I upgraded the Intel Rapid Storage Technology drivers to see if it yielded in any improvements.

I originally had version 11.7.0.1013 installed. This was what I had when I flashed the firmware. There was a newer version out when I checked it a few days ago. Version 12.5.0.1066 (download from here). I don’t know what happened to version 12 though. Maybe I didn’t check for a new driver in a while. I only got to know that there was a newer driver from OCN forums.

I first uninstalled the old driver and installed the new one, just to be sure. Updating drivers doesn’t go really well most of the times. Ironically, I always update the NVidia drivers, never uninstall the old one and install the new one. I do that because I haven’t had issues doing so in the past. Sorry, I digress.

BTW, I downloaded the floppy driver, not the Windows drivers. The floppy driver comes with… just the RST driver. But the Windows driver comes with their monitoring and management software as well. Since I don’t use Smart Response Technology or RAID in my PC, there is no need to install them. No need to add more junk to the PC. I want to keep it as clean as possible.

Here are the benchmarks, before and after the update. Both were done after I updated the firmware to DXT08B0Q. For the entire specs of the test rig, click here.

Before (11.7.0.1013)

After (12.5.0.1066)

So you see, there is nice speed bump after the driver update. I don’t think that is a noticeable difference. Heck, you cannot feel the difference between two SSDs to the naked eye, without running benchmarks anyways. I just got this SSD because it was the cheapest 250GB one available back in January. not because it is the fastest.
