There's tons of discussion on the web on this, but I've heard some consensus is going on, so I thought I'd get opinions from people who do video editing. My setup is: Premiere Pro CS4 on 64bit windows 7 Pro. laptop is Sony Vaio Z (VPCZ12GLX), i5-430M 2.26GHz, 4Gb DDR3 RAM, NVIDIA GeForce GT 330M (1Gb video RAM), 384Gb SSD. I wish to use an external drive to hold all my source media. I will access the external drive through an Expresscard. I can't afford an external SSD at this time, so I'm trying to get the next best thing. If I buy any hdd, I prefer to get something with an interface that will be fast and commonly used in the future.
Here's what I've heard:
Let me know your recommendations/ experiences.
eSATA is your best bet. Faster than any other connection, including USB3, and easy to get. Don't get lured by the theoretical bandwidth of USB3, in practice it still is slower than FW800, from what I have read.
The USB bandwidth has been effected by firmware on the NEC chips. If you update the Firmware then the performance should be just as good as E-Sata.
