Sure. I have a couple hundred TB in hard drive capacity and 1TB (4 x 256GB) SSD capacity.

I go for HDDs instead of SSDs because it would be cost prohibitive for me to achieve the same I/O bandwidth with SSDs that I can get on RAID 0 or RAID 10 HDDs and multiple 10GbE connections.

As it stands I'm already well into five figures between computing, storage and networking hardware. Replacing 24+ 8-10TB 7200RPM hard drives with equivalent SSD capacity would cost me nearly $100k in storage alone.
