"... Oh, and those of you looking nervously at your RAIDs: "SSDs which were put into service at the same time will likely fail nearly simultaneously.""

... And that is another reason why you should have backups ;)

Because your SSD manufacturer is using a *signed* short integer as a time counter.


@thomas aaaaaaaaa! i mean i have backups but still ... aaaaaaaaaa!


(Imagine Beavis and Butthead voices)

Dev1: hey we need a countrer variable, not sure about the datatype though

Dev2: let's make it a signed 8 bit integer so we can sell more SSDs

Dev1+2: <manical Beavis and Butthead laughing>

@Thomas Runge
Wo ist die News?
Ein "Raid" war noch nie = Backup ;-)

@marlon sowieso. Aber das Beispiel zeigt doch ganz eindrucksvoll einen zweiten Grund, wieso ein RAID kein Backup ist.

@Billie a signed short integer int16_t goes from −32.768 to 32.767, that is why I guess they’re using this data type ;-)

@thomas @Billie I learned at school that whenever possible you should avoid taking 2 drives into duty at the same time especially if they are the same model, what they most likely are if you build a raid. Now there is a reason more for following this instruction.
