snowmane Posted October 6, 2010 Share Posted October 6, 2010 I bought this SSD for use solely as an application drive. I've got XP 64 installed on a raid-0 elsewhere in the box. After secure erasing with Parted Magic and quick formatting as NTFS with 4096 allocated, ATTO shows the reads pretty much maxing out at 120-130 MB/sec. I thought I'd see close to 200. It's hooked to a JMB363 controller set to AHCI in the BIOS. "msahci" doesn't appear in the registry. Am I missing something here? Link to comment Share on other sites More sharing options...
Yellowbeard Posted October 6, 2010 Share Posted October 6, 2010 Do you have any way to test the drive on a newer maching using an Intel ICH8, ICH9, or ICH10 controller and also a machine using Windows 7? Link to comment Share on other sites More sharing options...
snowmane Posted October 6, 2010 Author Share Posted October 6, 2010 I can test it on a PC with an ICH9 controller, but it's also running XP. No Windows 7 in our house yet. I'll post the results. Link to comment Share on other sites More sharing options...
snowmane Posted October 6, 2010 Author Share Posted October 6, 2010 When I moved the drive to our Intel-based PC the ATTO results were much better. When I moved it back to my AMD/nForce 5 box and hooked it to the nForce controller the results were better yet. Light dawns on Marblehead: not all controllers are created equal.
