I rsync'ed about 400GB of data from one SSD to another across my LAN and now the new SSD is recognized only intermittently by the BIOS. Does the new drive have any hope or is it junk?

I do need to move that data across. How can I avoid this with my next SSD?

What is the make and model of the failing SSD? How much had it been used prior to this? I would expect even relatively old (2-3 years) SSDs to have much better write tolerance.

It is a brand new Samsung 850 Pro 1TB. Bought new from Amazon for ~$500 a few days ago and put straight to work writing the 400GB.

Already done. What is the best way to wipe data from the drive? I should be able to boot to USB and access it after a few attempts.

I don't think so because the solution there looks to be a kernel patch and even the BIOS is having issues detecting the drive.

Well, any other non-defective SSD will swallow the data just fine. However, if this is just about moving data over for the first time, why use rsync instead of, e.g., scp?

It could have been heat. I'm using the drive in a fanless Gigabyte Brix 2807 and the weather has been very hot lately. I've been running an identical system for a year without issue but I will ventilate the next time I move that data over.

Just a random bad drive most likely, something slipped through QC.

I don't treat my SSDs any differently than regular HDDs (though memory cards and USB flash drives I do...) and they've been just fine. Rsync, cp -a, tar, emerge, all work.

I guess my SSDs are "small" - a 128GB, a 180GB, and a 240GB (a Crucial and two Intels). The 128GB was taken out of service, but they've been main OS disks and I've run plenty of emerges on them, and they have swap partitions.

I have however killed many SD cards. I'm thinking bad QC as well, but who knows, could have been worn out with their less robust wear leveling.
