Did you upgrade to one of the new MacBook Pros and are unsatisfied with the speed of your hard drive? Don't think about upgrading to a Solid State Drive just yet. You would think that everything would get faster with the new MacBook Pros, but apparently that is not quite the case. MacRumors has uncovered that the SATA speed of the new 13" and 15" Macbook Pros has actually gone down, from 3 Gbit/s on the older models to 1.5 Gbits/s on the newer ones.
The SATA speed is relevant to how fast you can read and write to your hard drive. The difference of speed, thankfully, will not affect traditional hard drives, or even cheap SSDs, because they cannot take advantage of the higher tranfer speeds. However, this will affect you if you were planning to upgrade to a high end SSD at any point in the future. In fact, it would almost render such an upgrade useless, because the read/write speeds would be bottlenecked by the transfer rate of the system, not the SSD itself.
The strangest part of the whole story is that Apple supported the 3 Gbit/s standard, also known as SATA II, on the older versions of the same laptop. Our resident tech-experts at Maximum PC magazine say that there is no reason such a switch should have been made - SATA II has been supported for a long time, and in fact, SATA III, which will clock at 6 Gbit/s, is due soon. They say that there is no potential battery or space savings, and the only possible difference would be that the older hardware is slightly cheaper.
Are you upset about the downgrade to the MacBook Pros and will it affect your purchasing decision?
