Slow MacBook Pro on battery/after wakeup

[jonobin]

Lately I've been experiencing a slow Mac after about 1h of stop, after I woke it up it's slow, app takes longer to open and sometimes the Mac freezes while opening apps.

Immediately I've run trough Etrecheck to find what maybe the issue and it says that maybe the hard drive is failing, and that I've a lot of I/O(a bunch of times, apparently not anymore).

Lately I've tried DriveDx to have a better look at the health of the ssd(since every other test says that the drive is ok), and even this one says that the SSD is in a very good condition.

What tool is the most trustable? Is my drive really failing? What could be the culprit of the slowness? I don't have any type of problem if I'm using it attached to AC.

This may not be what you are looking for but ...

There is something called S.M.A.R.T which is essentially a set of register in the disk controller that save information about failures accumulated since the disk was new, operating time and so forth. Here it does not matter what SW you have, because it will basically just read out this information and present it to you. This is intended as a way to predict coming failures and warn you that you need a new disk. Maybe that is what Etrecheck is doing?

Then you can run test on the disk, basically writing and reading back. You have this built into the Mac.

A word of warning, my experience with SSD disks is when the fail they can fail completely and rapidly. So check your backups and get a new SSD.

Isn’t this the same thing that utility disk checkes? Even utility disk says that the drive is ok
