There's a story behind this SSD.
Kingston wouldn't be proud of it, but the truth is that almost every manufacturer of SSD has had the same problem. You'll notice that most makers of SSDs started in the RAM market. Technically that's an easy market - all you need to do is buy up a big manufacturer's surplus RAM chips, put them on a RAM PCB, and hope you'll make a profit.
But SSDs are a different proposition. Yes, you get memory chips, and yes, you sell the completed circuits, but in addition to the chips is a controller and this requires software. In the hurry to get newer and better SSDs on the market, sometimes the controller software isn't as good as it could be.
That's what happened at the initial release of this SSD. However, Kingston had another crack at the software, and managed to make an SSD that was faster and more reliable. The trouble was that people who'd bought the SSD when it first appeared submitted poor reviews. When you looked at the reviews, you could be excused for thinking that the current product performed the same.
So when the SSD came, I copied my C: drive to it and used it to start the system. I didn't time anything, but it seemed just as fast as my Corsair GT drive. I ran tests on it, and found that the performance was right up there with the SanDisk and Corsair SSDs. So, Kingston got it right, but of course you'd never know from the earlier reviews.
All my remarks about other SSDs apply to this one. If you don't have an SSD, get one as soon as possible. Scan sites like Dealnews for the best price, Google "optimize SSD" to get the most capacity, and you'll have a much faster computer experience. I now have Widows 8 64-bit, with the full Microsoft Office 2010, Photoshop 6, Reason, and Skyrim in 40GB. Also in that 40GB is Corel Draw X6.
I'd imagine that a 120GB SSD (like this one) would fit most people's lifestyle. If you exceed that, you put the lesser-used applications on your hard drive, and obviously files don't need to be on the SSD. My photos and MP3s are on the hard drive, because you may take an extra half-a-second to retrieve them, but then you spend many minutes editing the photos or listening to the MP3s.
So I'll say it again. A Solid State Disk will probably be the most apparent upgrade to your computer. And now that Kingston is in the top tier, this drive will be a good bet.
