Like a lot of people who ordered their Macbook Pros when the Unibody models were first released, I opted for an SSD to increase the speed of the computer. It has been a good year with the Apple SSD, but the benchmarks from Intel's X25-M G2 and RunCore SSDs are enough to make me think about upgrading. There are two things that can make me upgrade: 1) Considerable speed increases for the tasks I perform. 2) Increase in available disk space. Any SSD is faster than a standard HDD. That has been well established by reviews and benchmarks. My question is this: How much of an upgrade is it from a Apple (Samsung) 128GB SSD to an Intel X25-M G2 160GB or RunCore 256GB SSD in terms of speed? Benchmarks are fine to show the maximum speed of the drives, but what about real world results? How long does it take to open Firefox from one drive to the other? How long does it take to open Firefox, Adium, Safari, Open Office, and other programs considering the speed of the drives? Does the speed difference even matter? If anyone has any answers (other than "X opens instantly for me after upgrading from a HDD!"), I would appreciate it.
