I was looking around at new hard drive tech, and the Seagate Momentus XT caught my eye. It's very affordable (at $160ish) and its a Hybrid drive. What that means is they have 4GB of Solid state memory combined with a 500GB 7200 RPM hard drive platter. The nice part is that there are no complicated partitions or anything like that. Rather, the onboard chip copies commonly used data onto the 4GB SSD. This means boot files and stuff are read off the SSD, but you still have the advantage of 500GB at 1/5 the cost of the SSD. I was a tad skeptical, but i read this Cnet review. This hard drive beat the Intel X25M in read speed Also, at a 12 second boot time (i think they were using windows - meaning even better boot times for Mac OSX) It may actually be worth it Here's Cnet's review and tests on the drive. Any opinions? http://reviews.cnet.com/hard-drives/seagate-momentus-xt-500gb/4505-3186_7-34109211.html and here's the manufacturer's page: http://www.seagate.com/www/en-us/products/laptops/laptop-hdd Maybe we'll soon see better hybrid SSD's with 8 or 16 GB of Solid state memory and still retaining about 500+ GB of actual space (a must if you do video work like me).
