Thread-topic: [CRTech] SDD failure modes

Depending on the drive’s controller software, you’ll typically get some error notifications well ahead of time for the predictable failure modes. On the other hand, if it’s a random power surge or bit of misdirected static electricity that takes out the controller (much more of an issue with these all chip drives), then no warning would be expected. Backing up frequently is *always* best practice!

I personally go with Samsung PRO or EVO drives, with whatever number series is current (850 at the moment for the standard 2.5” form factor). PRO have a 10 year limited warranty, EVO have a 5 year limited warranty. So far probably 10-15 deployed in a mix of platforms and no failures or early warnings of loss/corruption. Samsung’s controller software is quite user friendly (though not as verbose now as with prior versions), which is nice for systems deployed to other users.

I would never recommend not running the mfg. provided controller software… they write it for a reason. : - )

Here's a general question for discussion...

My home computer's SSD just suddenly failed. No warning. Walked into the room to see the BSOD. Reset... "Hard Drive Not Found"

Pull plug, power back up: "Hard Drive Not Found" (Oh no!!!)

I'm just wondering if it's more common for "errors" to occur before an outright "toes-up" failure, or are we sometimes just going to get broadsided like this?

The kicker is, just the NIGHT BEFORE, I thought about the fact that I needed to make another backup... but a short time later, i powered down the computer. Thought about that backup, and dismissed it... "I'll do it tomorrow." (Famous last words!!)

Thankfully, my last backup was in April, and I had a slower, spinning drive I could restore it onto... and so I did. (Awaiting the UPS man with the SSD replacement drive.) Only a small amount of files were actually lost... but DAG-NABBIT WABBIT!!! IF ONLY I obeyed that "still small voice" the night before! :(

Happy Thanksgiving, all!
