SanDisk and Samsung have announced 19nm server-grade SSDs at impressive capacities or impressive speeds (but not both at the same time). In particular, SanDisk has unveiled the 4 TB Optimus MAX, a 2.5" solid-state drive (SSD) packed with 19nm eMLC flash, connected via 6 Gbit/sec SAS. The Optimus MAX is rated for 75,000 random read IOPS, 15,000 random write IOPS, and 400 MB/sec sequential read and write.
For those who would prefer speed and endurance over capacity, SanDisk also announced the Lightning Ultra Gen. II SSDs. With capacities of 200/400/800GB, these drives employ a SAS 12Gb/s interface and are rated at up to 1000/600 MB/s (4KB sequential read/write) and up to 190K/100K random read/write IOPS.

This is different from HDDs how?
The spacelike surfaces of time foliations can have a cusp at the surface of discontinuity. - P. Hajicek

Exactly. I just had a drive controller crap out on me the other day. No SMART data warnings of any problems. POOF, gone. Thankfully it wasn't important content.

See, with HDD's, you often get a clicking sound before the drive fails in a specific scenario. Which is of course of supremely useful when dealing with racks and racks of spinning disks.... and of course the time honored tradition to put a failing HDDs into the freezer... or was it the oven, to attempt to temporarily revive it long enough to copy off your data. Surely that won't work for SSDs.
I suppose their is likely scenario's in which HDD's fail that are better than SSD's, but if you aren't backing up your data, you are doing it wrong. Pull the failing drive, and either let the RAID rebuild, or restore from backup.

Since I moved into a tiny appartement I didn't have the space to put my computer in a safe place. This resulted in a lot of jolts to the case. Of course the computer developed symptoms: it got slow. After about 2 years it got so bad that I kept thinking it was crashing a lot.
Only after I exchanged the HDD was I sure that it was to blame. The problems disappeared and I wasn't able to get all the data off the faulty drive.
SMART didn't see any problems no matter what.

Same here, I've had quite a few drives fail on me over the last couple years - all spinning disk, never an error or clicking noise or anything.
Just one day it works, the next day it wouldn't spin up at all (try as it might). Technology changes, but the fact remains the same. You're only as good as your last good backup.

hdd will more often drop few bad sectors than simply VANISH WITHOUT ANY WARNING like every single SSD does.
