For encryption and tracking I would just use the built in FileVault2 encryption and Find my Mac. DriveDX and CCC are fine. Not sure why you would need to stress test stuff unless you are having a problem.

I am using Filevault now but had to go to Apple store for repairs and realize they ask for the password...so I feel encrypting by folder will be better instead.

I have a sizeable photo & video collection now (photographer enthusiast) and I'm starting to get OCD with hard drive failures. Thought it might be better to stress test newly bought drives for lemons before putting my stuff on there.

How often do you hand in your device for repairs that this would be a worthwhile consideration? Just wipe the drive and restore from backup once you get it back. Espionage uses plain-old, encrypted disk images (sparse bundles) and simply attaches these at the previous location of the folders, giving the illusion of a folder. This is something you can do yourself already. Apple moved away from sparse bundles as a substitute for disk encryption, because the system keeps records and caches elsewhere.

I think OS X has you adequately covered with FileVault, Find My Mac and Time Machine. You can use Time Machine with multiple disks too and rely on redundancy instead. You can also switch to a RAID set and have it duplicate your backups across multiple drives, which is exactly meant for drive failures.

If you're concerned about hard drive failures, you should also be aware of failure rates:

Find more info, including past reports, by googling search terms:
hard drive failure rates

You should also be aware of the value of redundancy. That means keeping multiple copies on different media, ideally in different places, like home, safe deposit box, etc.

I've went in to repair twice for GPU fail (2011 MBP). A year and a half after I bought it and than a year after first repair. So far, so good.

I can't wipe the drive when it fails...?

I'm aware of brand reliability and the to-do list for redundancy since I've been reading up on it. Thanks though.
The thing is every brand has hard drive fails so I want to test them out when I buy them. Exchange if needed when I'm still in the return policy.

You missed the part when they ask for the FileVault password
You don't have to give it to them. They will wipe the drive instead. If the drive is defect, then they will have no other choice anyway.

Which doesn't matter, because a- it's encrypted, so you feel safe they dont take the data, b- you dont give the pass, so your encrypted data is safe, they can't access it unless they want to brute force it. (and yes, there are news articles about bad apple employes taking naughty pictures off of ppls drives, so there's a reason not to give the pass, and to encrypt the data) and c- you obviously have a working backup at home, so restoring on a replaced drive is awesome, pro tip, ask them if you are on a HDD that while they are exchanging it, if you can pay (and for how much) to replace it with an SSD drive, that way it's done professionally, and you improve performance of the system. If you already have an ssd, perhaps you can ask 'if i give you guys my 1tb ssd i have at home, that i know works with this particular mac, can you guys replace it with that one?' ..
Who knows, options! while feeling safe.

I gave them the benefit of the doubt and give my password but I will just let them wipe it the next time around.
