I just bough a new Samsung SSD 470 256GB and have a problem with freezing system. Most often it appears when more then one operation is executed at once. System freeze for a couple of seconds and then come back. I run the test using Data Rescue 3 app and here's the result: screenshot Disk is installed in my MacbookPro 15 (Mid 2009) with the latest Snow Leopard release. What do You think, what's the problem?
