High traffic in MySQL can corrupt SD ?

I should have added you need to do this when the device is brand new, before you have written data to it. In some cases you might achieve the same if you do it after a format unit command, or after doing a trim/unmap over the whole device, but this is less certain and depends on the internal detail of how the device handles these commands.

Several manufacturers offer it to OEM's, but not necessarily to end-users. It's not the only variable - quality of the flash parts used is also a big factor, and the manufacturers sort their flash chips by various aspects of quality following testing, to be used in different quality/longevity/duty products.

Real hard information presented well

Usenet at its best.

My online web server will often under sever stress show 98%+ I/O wait, indicating that it has simply not got enough buffers.

Databases are HUGE resource hogs if the data size is big enough or the query complex enough.

And especially if the database is mistuned, i.e. there are commonly used joins that don't have supporting indexes on the tables being joined.

it also depends on the definition of "quickly".
