- cmer 16y agoDefinitely not. Firewire is MUCH faster than USB2, and it's still slower than having a drive connected directly to SATA for example... This new technology should allow external drives to be as fast as internal ones.
- jarek 16y agoNo - USB 2.0 is 80 MB/s theoretical, and you're lucky to get half of that sustained in practice. 20 MB/s is normal in my experience. Meanwhile hard drives have exceeded 100 MB/s on sequential read.
- phamilton 16y agoOne of the main problems with USB is the software implementation of it. Theoretical and practical are a wide split. Firewire is better in this regard due to the transfer protocol being done primarily in hardware. USB is designed to be more "Universal", so communication is delagated to software.
