I use a SSD in my laptop, but our servers haven't made the move yet. So, this is an important thing to remember. Once, I needed to write a program to deal with large DNA sequencing files (10-100 GB per sample). On my laptop, the program worked great, but on the server it sucked due to the disk IO. I ended up needing a completely different algorithm, but this wasn't at all clear when using my SSD. If only we could afford a few terabytes of SSD...

I'm using ZFS with SSDs as L2ARC and intent log devices, and standard SAS drives as the main spindles, all sitting in a JBOD enclosure.

It won't make purely random reads fast, but it makes my workloads scream.
