In case you missed it, we released a new firmware update for our SSD line yesterday. At the same time, we’ve been running tests to determine if there was any impact on performance.
Well, there is a bit of an effect in that this latest revision seems to smooth out the performance of the drive, lessening the variance in write performance considerably.
It’s probably just easier to show you.
We tested a 240GB OWC Mercury EXTREME Pro 6G SSD using the DiskTester diglloyd Tools both before and after the firmware update, and got these results.
As you can see, read rates stay right around the same speed and variance, but take a look at how much less varied the write rates have become after the update. You’ll also notice that while the variance has narrowed, it has narrowed toward the faster range. Now the minimum speed is right around the level that used to be considered the middle-0f-the road for this drive; it’s now slightly faster.
Granted, this increase in speed isn’t likely to be perceptible to most users – you’d have to be writing files in the multi-gigabyte range just to see a couple of seconds shaved off. However, the stabilization of and increase of write speeds may be an additional benefit if you choose to upgrade your firmware.
