Solid state disk drives are neat little devices, but they are HORRIBLE expensive, and they dont really give you that great of performance.

You are looking at around 500 bucks US plus memory for the basic models, and that doesnt include memory.

The problem with solid state disks, is they either have a scsi interface in the older ones, or a PCI interface as a plug in card. Both are limited in bus speed for data transfers.

Your system memory runs at a much higher bus speed than PCI or SCSI, so software based ram drives are usually better at storage.

The only useful thing that solid state drives gives you, is the nicer models have battery backups so you can reboot and still keep contents there for a short time.

They are nice if you can afford them though.
