"And the sad part is that other SSDs generally absolutely suck
when it comes to especially random write performance. And small
random writes is what you get when you update various filesystem
meta-data on any normal filesystem, so it really does matter. For
example, a vendor who shall remain nameless has an SSD disk out
there that they were also hawking at the Kernel Summit, and while
they get fine throughput (something like 50+MB/s on big contiguous
writes), they benchmark a pitiful 10 (yes, that's ten, as in "how
many fingers do you have) small random writes per second. That is
slower than a rotational disk."
