Hello, I tried to upgrade the original Hitachi 5K500 HDD with the Plextor PX-512M5P SSD and I got all those freezes, lockups and beach-balling. The system became unusable over time. Please, suggest ~ 512 GB (modern) SSD that will definitely work with that buggy MCP79 SATA controller. As I understand, I need a drive that could be locked to SATA-I. Thanks.
