Time will tell how the Momentus XT fares in day-to-day use. One word of caution: Go with a fresh OS install. It seems that copying a clone of a disk to the Momentus XT may result in performance actually degrading. I'll have more to report on that in a later post.
I've been lusting after SSDs since they arrived for laptops but couldn't bring myself to blow that kind of money. Considering the price and performance of the Momentus XT, however, I expect I'll be upgrading a whole lot of my gear in the near future. As for power and heat, the Seagate engineers tell me that it's a wash. At least my lap won't get any hotter.

Testing notes: Times are in seconds. I used a stopwatch to measure program load times, so one must take into account human reaction time. I would say that the margin for error on this test was plus or minus half a second. The MacBook Pro is a 17-inch model with 2.5GHz Core 2 Duo processor and 4GB of RAM. The original (OEM) hard disk is a Hitachi 250GB SATA, 5,400-rpm, 8MB cache (model HTS542525K9SA00). The Seagate Momentus XT is a 500GB SATA, 7,200-rpm, 32MB cache, and 4GB SLC NAND flash memory.
