I recently added a new 200GB Sata 2 (3Gbits) HD to my PC: Maxtor DiamondMax 10 6V200E0 I reinstalled Windows, and used my other Seagate 300GB (IDE) HD as backup. Everything went smooth, windows installed just fine. But now, when I benchmark the new drive with Sandra 07, I'm getting about about 69 mb/sec read on the physical disk test with a very high Randon Access time of 17-19ms. With the file system transfer speed I get ~57mB/sec and 14ms. I did the same tests on the other "slower" IDE drive, and got better results..!! (69 mb/sec read physical with 14ms, and 69mb/sec with 10-11 random access on the file transfer test) I know its not a big difference, but shoudn't a SataII drive be much faster than an IDE format?? I also tried HD Tach Bench and got these results: Maxtor 6V200E0 200GB SATA2 You can see the low average read of 57 mb/sec, and slow random access of 14.4ms (according to the drive specs. this should be more like 8-9ms) Even if it has a high *burst* speed, it drops pretty quickly. Now check out the secondary IDE drive Seagate 300GB IDE This draws a more stable line with a higher 64.9mb/sec and lower access time. Any Ideas?? I'm running an ASUS A8N32-Sli deluxe Board with Nforce4 chipset. I already installed the chipset drivers including Nvidia IDE/SATA drivers. Oh one more thing.. for some weird reason, windows detects my sata drive as a removable/portable drive. Of course, it won't let me stop the device. Please advise!
