SSD monitoring utility

Opinions on use of Hard Disk Sentinel? I've had it recommended as a means of being warned about impending SSD (and other storage media) failure, which I understand could, fail (ab?)normally quite sudden and catastrophic manner. Never used SSD before, but plan to put a couple in a Win . . . uhh . . . mass market GUI oriented "OS". They do have a Linux version also which I will test on my own. So there. Why ask here? Well, you all know everything, don't you? Besides, lack of hostile commentary has left me a bit nostalgic this holiday season.

You know about SMART? And smartctl, and smartd?
Happy New Year!

I think that my reply never went out ... I knew of SMART and smartctl (which is where I was rolling my own), but not smartd. THANKS! I've been digging in (as able around everything else) to see how to tweak and monitor its testing. YAY! :-) Happy New Year :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt

No different than a spinning drive (just much, much faster!). OS or what you use it with doesn't matter. I've run SSD for about ? 7-8 years now, driving them like I stole them, massive compiles, never had any issue. The failure rate today is remarkably small -- and not something you will experience within double or triple the warranty period (absent dropping laptop in a puddle, etc..). The way they measure failure rates is with a percentage of drive rewrites on a daily basis. If I recall correctly it's a rewrite of ~70-80% of the entire media every 24 hours. Which if you have a 1T drives means rewriting 700-800 GB daily every day for the MTBF days. Unless you are moving music or videos around, you likely rewrite less than 5% on a daily basis -- so drive life due to use is measured in tens of years at that rate. (granted that's just using the published MTBF use calculation for your daily rewrite percentage, and doesn't account for a chip or other component failure) Bottom line, you don't have to baby a SSD, just use it like you used a spinning drive and you can expect equivalent or better lifetime out of it. The OS/filesystem take care of drive-trim for you now, so you don't need to worry about that. I've got no complaints against SSDs, just enjoy the 5-6x I/O rate. It makes even older hardware feel snappy. I've got Tumbleweed booting in just over 12 sec - poweroff to full kdm3 (you do need to tweak the wait-time for network devices to appear to get boot times that low) smartctl is all I have for monitoring, and haven't seen the need for anything else. -- David C.
