Summary: performance is great though I connected it to SATA2 port which will only bring up its speed up to half of what it is capable of. Indeed, my Samsung 840 Pro had slowing down issue as I keep using it for about two month or so. However, as its reputations, Plextor SSD's true speed works. It's been a month with around 60% of its memory is in use, I never experience freezing or slowing down due to high usage.
Summary: This SSD was intended to be used for a Windows 7/Linux multi-boot configuration, replacing a couple of hard drives. It has performed flawlessly since then. The drive is attached using a SATA III connection and performs well regardless of workload. Both Windows 7 and Linux run much better as compared to the older hard drives, which was expected. There isn't any negative I can say about the drive. This is my first SSD so I can't compare it to other drives.
Summary: I have been using Plextor products for years. Everything has always been reliable so I thought a Plextor SSD would be the way to go for my first SSD. Installation was a breeze. I did not bother with their software to copy over the contents of the old hard drive. I performed a clean install instead. Boot time is now just a few seconds. Breathed new life into an older laptop (core 2 duo).
Summary: Plextor has made fine optical drives for a long time, and now they're making great SSDs too! It's not the fastest they make, but it's very fast, nonetheless. It reviews very well in synthetic and real world benchmarks. To me, it's just plain fast when to compared to other SSDs, plus the ones I own. It also has nice garbage collection of its own: the Marvell (yay!) controller and Plextor's great firmware coders see to this.
Summary: First time installing and using an SSD. I primarily put my OS and programs such as photoshop onto this drive and everything else on a standard HDD. Have absolutely no problems during install and it's running great, no problems since. Boot up times are significantly improved (takes about 10-15 seconds for a complete power up) and thinking about getting another one!
