and there should be SMART data available for the SSDs. just need software to get it. the CF cards we use in the amb-os rcvr have SMART data. might be able to predict a failure or monitor end of life that way. you can only erase them so many times ya know. that's why it's best to have both. SSD for system files for fast bootup and don't change. spinning HD for filesystem - files that change a lot.

but to have it not respond at all. very bad.

Stick with Crucial/Micron, Samsung, and Sandisk in a pinch.  I haven't seen anything good or bad about the newer Western Digitals, but the other three I mentioned are good.


And although Sandisk is king of SD cards… I would put them at the bottom of the stack of three that I just mentioned…  They work, but they don't perform the best.

I wasn't in the room to witness the actual failure, I walked in to see a BSOD. :(

I also tried to access the drive with an external USB/SATA interface on my XP machine, and on a WIN7 machine. No go, either way. The interface was visible, but the drive was inaccessible. Dead as doornails. :( I tested a different drive in the interface, and it worked perfectly. (I've used that interface many times, so I know it's a good one.)

My SSD was an off-brand. This time, I got two identical SanDisk drives with hundreds of 5-star ratings on Newegg. I'm just waiting for the UPS man, now. ;) According to the tracking, I SHOULD have the package tomorrow! (Tues)

I praise God that I had this April backup, and an old SATA laptop drive to get me back up and running! :)

Windows XP does not have TRIM commands, so if you did not install the manufacturers software (and I believe you have to manually run it from time to time), the drive will not be TRIM’ed and I believe this causes failure. Not sure if it’s irreversible failure, or if that is what happened to your drive Willie, But something to consider.
