... Unless your workload is very specifically single source, massive
capture, then you should be running SSDs. Even if you are not running
pure SSD, the case for tiered or hybrid storage makes itself.

SSDs are faster. They have way lower latency. They consume less power.
They take up less space.

You do need to choose wisely if intending to store highly compressed
binary images on them. Plenty of makers game the benchmarks by using on
the fly compression to get maximum headline read write speed.

Samsung 840 is pretty good and you generally want something sized at
256GB or above so that all the memory controller channels are populated.
You can RAID0 them too for scratch disks if you want more bandwidth and
are prepared to accept the increased risk of failure.
