And not the question you're likely expecting. Quite the opposite. And I'm going to ask it with an analogy. With the airport backscattering technology, the government and the TSA say that they are perfectly safe and will not harm human tissue. Specialists say that repeated exposure to even light amounts of such direct skin radiation can be harmful to those with pre-existing conditions but the results won't show themselves for many years. Nothing might happen for all we know, but the point is it will take time to know the definitive answer. I see a lot of people talking about SSD and TRIM and garbage collection. SSDs, at least in the mainstream sense, are fairly new as far as presence in laptops. There are a few models out, but they haven't been out enough to really put them to the paces in terms of performance degradation. To really know, one would have to use such a drive for literally years - 5-10 years - to get a solid enough picture. Then it's really user perception of speed degradation, rather than what some benchmark tells you. Because as we all know, if I'm looking at how long an app takes to open, I can tell when it's slow and when it's not. The general rule of thumb is, when my free space drops below 5GB, the drive will be somewhat slower until I free space. I have an Intel X-25M 80GB SSD in my MBP17". I'm aware of its speed compared to old platter drives, including 7200 RPM platters. I know that if I were to have the exact same image on an OCZ, an OWC, a Kingston, a Crucial, a WD, or an ADATA SSD, I would see the exact same perceived performance. In effect the only thing I really need to care about at this juncture is the reliability of the drive itself which, again, isn't really known due to the newness of the technology in the mainstream as well as the fact that some of these manufacturers are fairly unknown in the SSD realm. What's more, the tech is improved almost daily, which means an Intel that you did buy 3 years ago might not be as reliable as one bought today, obviously. Thus my question: Why are people so hung up about TRIM/garbage collection when we don't know if it really matters in a day-to-day usage situation and won't until we get extended usage reports from regular users having used a given SSD for 5-10 years?
