Pretty common for router/switch manufacturers to include just 1 storage device (SSD/CF/whatever). That's one reason why you buy the second router/switch for redundancy.
Most people would have to walk through smog and traffic, and literally enjoy a cold concrete paradise. This doesn't sound enjoyable for meandering. I long for a rural life.
I'll say this again about coinbase, I'm convinced they are playing the market on peoples investment. I bought when bitcoin was starting to rocket, they tied my money up for weeks, bitcoin doubles in that time. Then after that I get a sorry letter and my money back. What was my money doing in that time? Probably making them money.
Yes, yet youtube is still advertising horror movies to my 2 year old watching kids videos. Other than Rockenblox I've barely seen a ad that is 'kid' related on kids videos.
Regardless, I've noticed the same thing on YouTube, they really need to fix that. Why are you running an add for car insurance on a video obviously geared towards children? I mean, why are you advertising at all on videos clearly geared towards children.
10 years of growing up watching gocompare or "compare the market" adverts means when they do turn 17 they'll instinctively know where to go for their cheap car insurance without a second thought.
We used to make PODs like this at work for netbackup storage.. started with WD drives ~128 WD drives, at about two years we were at ~8 WD drives still working. At least once a week we had people in there swapping drives. I have yet to see a WD not fail.
On the other hand, I've got a WD Caviar Black that's been running strong for more than five years. None of my WD drives have ever failed (knock on wood!). I don't run 100+ drives though, so I'm probably just hiding in the statistical margin.
Your Caviar Black is trumped by my two Scorpio Blacks I had to RMA in one year because of strange read/write delays and clicking noise. No actual failure, but it started from one problem/day when I bought them to 3-4/hour when I sent them back.
Also your thermal environment is going to be quite different, which could be a significant factor. How often do you power-cycle that drive BTW? I've had more drives go bad on power-up (just failing to spin up and move the heads correctly) than through surface errors and such.
That si better than running the drives 24/7 - if one is going to go then that way it is more likely to go alone. If every in an array (anything I even half way care about get s the RAID1 or RAID5 treatment) has been spinning for years then a power cycle can be quite scary. Restarting once month or so increases the chance that if they fail they'll not all fail at the same time.
Having said that, my main little server at home hasn't had a power cycle for somewhat longer than a month as there have been no kernel updates or that like that have required it...
