Welcome to our new server. It should be much faster as everything is hosted on two SSD's now Also, we got some hours downtime with the old server and lost 4% of all attachments due to fatal corruption of our RAID1 array which we were not able to recover using backups. We are still trying to find ways to recover the lost files.
something i've noticed is that some new posts will still show up as invalid attachments, while some new posts will do that then fix themselves after a few seconds
Long... for example the Samsung SSD 850 should at least work for 10 years under normal use. I know, server isn't normal but many servers these days take SSDs!
Lifetime yes, but P/E cycles are going downhill. And compared to HDDs they can't compare. Lifetime doesn't matter when the cells are weared down. This used to be higher, but as with CPUs they have to shrink the chip dies to make it cheaper to produce. And this makes the P/E cycles lower and lower. 3D NAND is interesting though (vertical stacking of dies instead of shrinking). They're at 30-40 nm with 3D NAND (MLC) compared to below 20 nm. And with TLC it's even worse (shouldn't even been brought to the market), cutting the voltage threshold for the NAND.
Actually the lifetimes in terms of disk wear are calculated at over a decade for most users on current disks. There have been a crap ton of independent tests on it recently. I do know someone that is still using an ssd as a boot drive, the same one he bought when they were first made available to consumers. The short lifespans of ssds is just bullshit.
