I’ve had exactly two dishwashers completely stop functioning in my entire life. Both were GE post Haier and within the last 6 years. Also had a Haier made GE microwave completely fail.

I replaced the microwave (and the matching stove) with Samsung and haven’t had one bit of trouble with either.

I thought I had just gotten a lemon, but three separate failures within a couple of years has really soured my opinion of them. I was a lot more worried about the Samsung appliances I bought, but they’ve been a dream.

Note: I am not recommending Samsung appliances, at all. I got an amazing deal and fully expected them to fail shortly after the warranty was up. I’ve had to repair several of my friends and family’s washers, dryers, and refrigerators. Samsung’s poor reputation is well earned, I just got lucky

It’s just easier to access and in a prettier box, covered in advertisements.

It is the only approved method for data destruction for the several banks and government agencies I support. If they trust it, I trust it.

I have checked a couple of times out of curiosity, after a secure erase the drive is as clean as if it had been DBANed. Sometimes things are standards because they work properly.

They’ll have to get a new SAS controller unless the RAID controller has an HBA mode. Running ZFS under a RAID controller is the best way to lose all of your data.

ZFS is wonderful but it takes quite a bit of planning and specialized knowledge to implement properly. Your fear of a failed RAID controller is a bit much, too. I’ve had to deal with a single controller failure in 30 years of IT (and I’ve done warranty work for all of the major OEMs in corporate IT for most of those 30 years)
