If I read the specs right at the HP web site, this laptop has eSATA which I've used in the past, and it works very well. I'm currently using USB 3, but I see this laptop doesn't have USB 3. I've never used Firewire, but I understand its speed is close to that of USB 3. I'd say that if you can find an external hard drive with eSATA or IEEE 1394, you'd do well. Bear in mind that most of the external hard drives run at 5400 rpm, so I use enclosures with the features I want and put 7200 rpm hard drives in them.
I've got to back up my files before disaster strikes. From what I've read doing a mirror backup seems best so I'm asking the experts what is the best external HDD to get ?
My laptop is a HP dv7 3085dx 64bit Hm.prem. with a fire wire (1394) port. I have a two ended male firewire cable that I'd like to use if there was an Ext.HDD having the same port for file transfer. Otherwise, I could use the slower USB 2.0
Thanks for help with this.
