It is. As a home user I don't want more than 10 TB of storage, but it would be nice to have things like my game library on an SSD RAID array that can be mapped by multiple desktops and laptops. IOPS and latency are more important than throughput in terms of responsiveness and UX for general file usage. Hard drive arrays of any size are always going to have abyssmal IOPS. SSDs are also silent and low power. They're the right pick for a box that stays in a room where I live.
