[quote=no_such_reality]Frankly, buying SSD is like buying a Ferrari for your morning rush hour commute on the I5.[/quote]
I’m guessing you haven’t spent many hours working on a machine that has an SSD, or perhaps you have the patience of a Zen monk. Also, the Ferrari analogy is not a good one. The vast majority of the waiting-for-things-to-happen on a computer is caused by disk latency and throughput issues. The one piece of hardware that most limits the speed of a PC is its hard drive. Modern SSDs have essentially zero latency and deliver data run fast enough to saturate the SATA bus. The disk is no longer the bottleneck.
I switch tasks a lot, need to compile code, and do lots of other disk and CPU intensive tasks, and I find that removing disk latency from the equation is a huge productivity boost. Need to open an image file for that web design issue? Kablam! there it is. Need to open some hog of an application to fix that document? Boom, done. Those 15-seconds there, 30-seconds there pauses that punctuate the work day add up, and you really notice it when they’re gone. And you REALLY notice it when you switch back to a spinning platter.
The reliability issue requires that you stick to a watertight backup strategy, but i’ve never seen a single-bulled productivity boost like the one an SSD provides.
