I have a P5B Deluxe and I bought an external HDD with eSATA and the tranfer rate is extremely slow using eSATA. I thought it could be a HDD issue but I think it might be a motherboard issue seeing that others with P5B Deluxe MOBOs are having the same problem. Is this an issue that can be fixed with driver or BIOS updates?
Hey pchoi4 what os are you using and what external drive are you using? I just got a Wd My Book prem 320 gig drive with esata. Im waiting to get my esata cable Monday to test the esata transfer rates. My average usb speed was 5mb/sec. I reformatted the drive to Ntfs then in device manager in vista made sure the policies was set to performance and my average speed went to 9 to 10 mb/sec. Thats the suggestion someone gave me and it helped a little. Transfer rates are fast when i boot in xp.
Did you fixed this problem. I have exactly the same issue as you. My HDD is a FreeAgent Pro, 750GB on Vista 64-bit. I'm about to go to work, but I'll look for new eSata drivers tonight. Let me know please if you found any way of fixing this.
