My MacBook Pro (mid-2012, 16GB, i7 2.3) has started to misbehave:
- very slow to start up and shut down
- application launches are slow
- system becomes nearly unusable when "free" memory approaches zero.
Disk Utility is showing SMART status of the drive as "verified". However, Blackmagic Disk Speed Test is showing a read speed of 27 MB/s and a write speed of 25.7 MB/s. This seems slow to me, though I'm have trouble finding any benchmark values to compare against.
I've run "verify disk" in the Disk Utility app twice. The first time it completed with no errors. The second time the computer froze before the procedure finished.
Here is the system profiler information for the drive.

Does any of this indicate an imminent drive failure? The AppleCare plan for this computer expires in 6 days.
