Nearly a year ago, we reviewed the Kingston SSDNow E100 200GB and found it to be exquisite. It could even be one of the finest MLC-based second-gen LSI LSI SandForce drives we raved. That's pretty high praise for an enterprise SSD. Since that time, a lot has changed in the enterprise market. As we have discussed in previous reviews, a new category of enterprise SSDs has emerged; one that combines the low costs of MLC devices with enterprise SSD features, such as power loss protection. With its new SSDNow E50, Kingston is the latest company to venture into this market.
