I'm debating whether to get the Solid State Hybrid Drives from Seagate. http://www.seagate.com/www/en-us/products/internal-storage/momentus-xt-kit/ Or the Western Digital 750GB/7200RPM. I hear seagate is less reliable and glitchy? Western Digital is more reliable and more secure? But those are just rumors, anyone actually try both or whatever? Like... is the battery life still about the same? How fast does it run/boot time/etc? Does it make a lot of noise? Thanks.
