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??
eSATA is notorious for bad / buggy implementation in hardware and BIOS support. I'm not surprised by your experience and can share similar. – user12889 – 2010-04-19T05:40:26.187
is your motherboard SATA controller in AHCI mode or IDE mode? – quack quixote – 2010-06-15T17:06:06.240
Have you tried using a different eSATA cable? Perhaps the one you are using is bad. – firedfly – 2009-08-29T02:18:06.627
