I have just bought a WD My Passport Studio portable 2TB Firwire 800 hard drive to use with my 2009 MacBook Pro 13" 250gb laptop.
I know that the computer’s internal disk speed matters, but for a time machine backup for 150gb it’s estimating 3 hours, that means the transfer rate is around 120 mbps rather than the supposed 800 mbps that justifies the added expense of using firewire.
Any suggestions on why it’s so slow and how to speed it up? I put the Mac’s internal sata through it’s paces, but I would still expect a significant upgrade from my previous USB 2.0 drive.
Cheers
