For the past couple of days i’ve been thinking about switching my 750 GB HDD in my Alienware M14x to a 256 GB SSD and replace my optical drive with a 2.5 Inch bay area that i can fit my current HDD in. SDD technology is now a lot more stable than it used to be when it came out, speeds have increased and storage and fetching algorithms have also improved, increasing the life and reliability of SSD drives. So the easiest way to get some more speed from your current laptop would be a simple swap. Only downside is the price of SSDs are somewhat higher than the conventional HDD.
