i installed this solid state hard drive into my laptop this weekend: Samsung Electronics Samsung 840 Series Solid State Drive (SSD) 500 GB.
so far, it’s great! boot time is about two seconds on average! two freakin’ seconds for a full boot! i expect an improvement in power consumption as well as the speedy read/writes.
the only drawback is that it’s 250gb less than my original hard drive. i am going to have to be diligent about my photographs (imported from my camera) and virtual machines. those two eat away at my space quickly. (but the VMs i do have should run much quicker now.)
added: this link is to a video of the improved boot up:
