Hello all, I'm looking to buy a 2011 MBP, and I'm wondering if I should jump on the 128GB SSD upgrade, or go with one of the standard HDDs. I'm obviously worried about the small space available on the SSD (bigger SSDs are way too expensive ATM). So, I'm wondering about the practicality of going with the internal 128GB SSD, and then buying a portable disk drive to hold any extra apps and media. Probably also buy a big external for backups too. So, my question is what the data read/write speeds are like for external hard disks versus internal ones? My present HDD is a 120GB, very small, very slow, and a couple of externals.
