We have to change some of our thinking when looking at a drive designed and marketed towards business users. The workload is quite a bit different than what enthusiasts put their drives through.
As an enthusiast I work with a lot of media files for myself and my family. I keep a notebook around that is used just for work and after examining the files on it, I can see a big difference between the work notebook and my play notebook. I also captured my wife's work notebook to examine her files as well. With my work I keep a lot of product images, PDF files and Word Docs like the one I'm writing this review in. There are over 300 reviews kept on this notebook in the Completed Reviews folder, another 15 or so in the Pending Reviews folder and several thousand images. My wife doesn't work with images at all, but has thousands of documents in both Word and PDF. She has to deal with health care reform for a large international health care provider so you can imagine the massive number of documents floating around on her encrypted hard drive.
That leads us to a very important issue. Encrypted data is presented to the HDD/SSD as incompressible data so if you are in charge of 500 notebooks and are looking for a SSD to use in all of them, a drive that performs poorly with incompressible data (such as this one), isn't the best choice. Then again, if you have a mechanical HDD in there that is as slow as my wife's, then anything solid state would perform better than that thing.
When you are working with large clusters of documents and checking your email, the Kingston SSDNow V+ 200 performs very well. Getting off of the compressible data path though really starts to slow things down and it is the kind of slow that you notice. Also, when the drive is more than 25% full you notice a large slowdown in performance when working with larger files. In the image above we see the file transfer from when we moved from 50% capacity fill to 75%. The data traveled from the drive back to the drive and did so at just under 60MB/s. That is still faster than most mechanical HDDs, but in SSD terms, it is pretty slow.
If you have a little more available in your budget I would recommend migrating over to the Kingston KC100 SSD. This model uses synchronous flash, but costs around $35 more at Newegg. You won't take as large of a performance hit when working with incompressible data or when the drive tips the scales in capacity used. For encrypted systems I would say the KC100 is your starting point because everything the drives sees will look like incompressible data.
For those looking to stay within a tighter budget, the V+200 will certainly be better than a mechanical HDD, but there are better options available from Kingston, if you can fit them in your annual budget.
It should be noted as well, the V+200 is stable with the shipping firmware and you won't run into any BSOD issues that have been reported with other SSDs in the past.
