Hell, I remember reading PC Mag and being SHOCKED about a 4GB HD that cost a few hundred bucks. (Also shocked that I subscribed to PC Mag.)
I was shocked when 200GB drives were called drivezilla and cost $400.

> The first disk died late on Friday. I had two on-hand so I casually replaced it -- and before I got back to my desk another had died. That happens very very very often. It has nothing to do with a bad batch. The second disk actually failed a while ago, but no one noticed because no one read from that part of it. When you did the rebuild you read from the failed area and woke up the failure. When you setup raid you…
Is there a well known tool to check for this?

They're not guaranteeing failure in 5 years, but are pretty sure it won't fail. If "pretty sure" is 98%, then that's 100K (or something like it, probability maths is hard).
Thet aren't guaranteeing anything. They are saying they will replace it if it fails inside 5 years.

Samsung's 2TB SSD is $860 so maybe something like that. http://www.amazon.com/Samsung-2-5-Inch-SATA-Internal-MZ-7KE2...
That's a consumer SSD. The 16TB looks like an enterprise SSD (much higher endurance).

You're asking for 2 major tech steppings in a single product. We don't even have many mass market NVMe drives yet, and that aside, they're undoubtedly pushing the limits of their existing controller tech just to handle the capacity. Has NVMe seen much enterprise adoption yet? No surprise they chose an interface to match their intended customers' existing product lines
We put a couple of Intel 750s in our primary DB server and so many of our issues just went away instantly. Reading at 2GB/s is amazing. On a 10gb network, our network backups now happen at 1+GB/s. Of course we optimize our DB queries as much as possible but sometimes, you just hit a brick wall and can't speed things up because of how the data is structured. Instead of spending 100 developer/dbadmin hours on reorganiz…
Their EVO drives suffer from read degradation slowly over long periods of time. See EVO 840, after about a year it was down to 20MiB/s of continuous read speed. An SSD they call that thing. They refused warranty and released a "Speed up flash warez tool now.exe" as help, which all it did was move the data around on the SSD in the background so as to keep up the charade that their SSDs dont suffer from manufacturing/design error.
The 15.36TB PM1633a drive supports one full drive write per day, which means 15.36TB of data can be written every day on a single drive without failure over its five-year warranty. In other words, assuming good wear leveling, each bit can only be rewritten ~2K times, which is actually quite low for endurance... the capacity is high and they're using that to hide the fact that it's low, but if this was e.g. SLC flash…
SLC and MLC endurance aren't much different: http://hothardware.com/news/google-data-center-ssd-research-... To reach a full rewrite a day, that's like 200Mb/s consistently over the span of a 24 hour day. If your loads/usage looks like this, you're probably expecting your drives to fail and are ready to replace them.
Samsung can try to sell me 100TB SSD, and Ill decline thanks. Their EVO drives suffer from read degradation slowly over long periods of time. See EVO 840, after about a year it was down to 20MiB/s of continuous read speed. An SSD they call that thing.
