Anandtech has a review of Gigabyte's i-RAM card that they had debuted at Comdex. It's a card that you can place conventional desktop DDR memory into that fits into a PCI slot, from which it only draws power, and then connect via SATA to your computer. It then asks as a real disk, but based off of memory. Cheap solid state storages for the masses.

The benchmarks are interesting; the performance increase is nowhere near as to be expected. It's flat out lousy, at least for how little the storage is and how much it costs.
