When you're evaluating an SSD and your goal is to get your system to boot and start applications faster, the write speeds are pretty much the least important thing to worry about. What you should pay the most attention to is the access time, which is shown in "random read I/Os per second" benchmarks.
So then this
unit would make a very suitable boot drive? As long as it is an improvement over my 7200 RPM seagate that I'm using as a boot drive now, the mission has been fulfilled.
