SSDs currently peak somewhere around 7GB/s transfer speeds, while RAM can easily knock out well over 20GB/s (and that's a low estimate). So anything that benefits from fast transfer speeds and/or low latency will appreciate a RAM disk.
SSDs are also consumable, as mentioned in other comments, so RAM disks are perfect for a scratch disk. HDDs can also serve as a scratch disk, but some tasks also appreciate the aforementioned faster transfer speeds and/or lower latency of SSDs or RAM.
