It does take a little longer so whether it's too long is strictly a personal question.
I am buying a new laptop, and I am worried that an SSD drive will not provide me with enough storage. Could it make sense to use an external drive for storage of music and apps for my iphone and photos? Or would transfer rates be slow from the PC to the hard drive and back again? Would using an external hard drive defeat the purpose of the speed of an SSD? Thanks!
