I've got 2x 60gb SSD's one for startup and a second for work in progress with 2 standard drives for storage and archive/music. My MacPro 2.8 Quad core running 10.9.1 is working fine in applications and general running but anytime I need to use finder it freezes for 10-15 seconds. If I ask to open the wastebasket it takes some time before this happens. If I open the startup SSD it takes about 10 seconds before it displays its contents. All the other HD's open and display instantly, just the startup ssd is slow. The work in progress SSD works fine just the startup one. The problem SSD is installed under the optical drive not in the HD bays. It used to work fine now it doesn't. Any suggestions?
