Why I'm usually unnerved when modern SSDs die on us

Users and administrators almost certainly prefer a 20 minute IO latency over data corruption. Host operating systems should probably flag an IO as failed long before 20 minutes and then you know 1) nothing made it to disk and 2) have some chance to avoid introducing additional corruption, if e.g., the OS is smart enough to kick out the drive when this happens. > Another problem is that the job while rewarding is not…

As someone that identified a bug in a Drobo firmware once and was offered a job on the spot I think the problem with attracting talent is two fold. The first problem is really two parts, not only is it rare to find people who have passion for storage related technologies but very few will gain exposure to these technologies to develop that passion. Kids don't routinely grow up with a SAN in the house. They do tend to…

I don't know how the system could / should interface with stupid trends sucking resources (high complexity projects, smart individuals, long term).

The business would have to offer employees something lucrative they otherwise wouldn't earn. I'm not sure what that would be however.

One potential cause is poorly constructed drive firmware which fails to account for a minor failure of some kind and crashes. If that unaccounted minor failure is persistent, the firmware may crash constantly and then you'd be unable to access even theoretically good parts of the drive. Firmware -- undebuggable, unobservable, unfixable software, jammed into your devices -- is the enemy.

Sounds like there is a business opportunist here for open firmware or even one running on the CPU especially for the enterprise? But maybe they won’t bother either despite valuable data and uptime, and just rather throw more redundant SSD’s at the problem.

Let's be honest, the chance of a multi-million dollar payoff for an employee is low regardless. Young entry-level devs are optimistic and also vulnerable to believing a line of bullshit on how much their options might be worth some day. I do agree it is a "higher" chance in web/mobile technology, sort of like how your chance of winning the lottery is "higher" if you buy 10 tickets instead of 1.

You still get paid a lot more working at google working on generic backend protobuf shuffling than you will working on SSD firmware at a hardware company or intel's C++ compiler.
