Hello all.

Have a funny issue I thought I'd run past you. My P4 3.4 system is running two SATA 1 seagate drives. One is an 80GB and the other is a 160GB drive. The mother board is an Asus P5GDC Deluxe with 1GB of ram and a Plextor SATA DVD burner. I use Passmark Performance test to test the drives to make sure they are up to speed. On this P4 I get approx. 50MB/sec Sequential read and 51/sec Sequential write speeds by all accounts is just fine. No Raid and is setup in bios as Enhanced IDE as it should be. I have no problems with this system.

However, I just assembled a Core2 Duo 2.4GH system with an Asus P5B Deluxe board with 2GB of ram. I have two Seagate Sata2 drives. One is a 250GB and the other is a 320GB drive. This is a SATA2 board with SATA2 drives. I would have expected at the very least to have the same performance, but I don't. I have the latest 1101 bios loaded and both the systems have WinXP Home SP2. On this new system I'm getting 65MB/sec Sequential write, but only getting 39MB/sec sequential read on either of the drives. Now, I'm getting a little faster write times on the SATA2 drive which are what you would think, but the read times are much slower. I tried disconnecting the secondary drive and just running the boot drive, but get the same performance. I would have thought the SATA2 system would be at least as fast or maybe a little faster, but not slower.

Any thoughts on this would be greatly appreciated.
Thanks
Patrick
