24nm Flash SSD Faceoff - SanDisk Extreme Retake and Plextor M3 Pro

With two new 24nm flash based SSDs in our labs, it was time to put them face to face.

On February 28th we published our first review of the SanDisk Extreme 240GB, the first 24nm flash drive on the market with a SandForce flash processor unit. In the review we focused mainly on the low price point of the drive since the performance was still very close to the large number of Team SandForce drives using 25nm IMFT flash. What we didn't know at the time was our test systems were compromised in some way. I would love to give an explanation, but I honestly don't have one. It wasn't just the primary test system, but both identical systems and even a fresh build system based on another chipset, the older P67 test rig.


To make matters worse, even a brand new build based on another company's Z68 board did the same thing. After spending 18 to 20 hours a day working on the issue Chad Sebring chimed in with an idea, look at the drivers. All of the systems were using the same chipset drivers, but we were trying different RST drivers. After downloading a different set of drivers from a different web page we had TRIM again. It's safe to say that for the next couple of weeks I will hate computers. I HATE YOU COMPUTERS!!!


Today we are taking another look at the SanDisk Extreme 240GB, this time with TRIM working. To spice things up a bit, we're also including performance data from the new Plextor M3 Pro SSD in our charts. While we were playing driver investigator a pair of new M3 Pro drives hit our lab. Normally we'd have these drives finished up and the review posted within a couple of days, but obviously we were having some issues.


The Plextor M3 Pro is the newest SSD on the market to use Toshiba 24nm Toggle Mode flash. The SanDisk Extreme uses the same flash, made at the same factory, but sporting a SanDisk badge. These two drives, the SanDisk Extreme and the Plextor M3 Pro are the hottest new SSDs on the market, with the fastest flash available. They have one very big difference though, the SanDisk uses a SandForce SF-2281 controller and the Plextor M3 Pro uses the ageless Marvell 88SS9194-BKK2.


In a couple of days we'll have a full report online for the two Plextor M3 Pro SSDs. Till then, let's take a look at the performance of these two new "it" SSDs and see how they compare, this time with TRIM working.
