Why would an external eSata Drive (xSonic with 500Gb notebook Hard Drive) run ok on a Silicon Image based PCI-E to eSata adaptor at about 35MB/s, But then run really slow when plugged into NForce4 Sata socket via cable?

I have another version of the problem with Really slow 1MB/s!!! performance on a ASUS P5K Pro Motherboard with E8400 CPU. This time the same card is plugged into a PCI-E socket. The same eSata drive is plugged into the Esata port on the card.

All this is running on Windows XP Pro 32bit.

Any suggestions on how to diagnose the problems??

For performance reasons go with eSATA or 1394 for external HDs. Why spend the money on USB 3.0 next year,even if the prices come down… >>> More

Improving VPN performance - stronger encryption = more performance?

I have a site-to-site VPN set up with two SonicWall's (a TZ170 and a Pro1260). It was suggested to me that turning off encryption (so the VPN is tunneling only) would improve performance. (I'm not concerned with security, because the VPN is running over a trusted line.) Using FTP and HTTP transfers… >>> More
