The Register heard Hitachi has presented an enterprise SSD at the Hitachi uValue 2010 convention in Tokyo:
There is very little information available but we know it's a 2.5-inch form factor product with SAS and FCAL (Fibre Channel Arbitrated Loop) interfaces, making it a product to fit into a 2.5-inch small form factor disk drive slot in a SAS or Fibre Channel disk drive array. Currently STEC is the only supplier of Fibre Channel interface SSDs with the ZeusIOPS line, available in both 3.5-inch and 2.5-inch form factors. Most enterprise drive array manufacturers offer STEC SSDs. With this product Hitachi GST could offer itself as a second source to small form factor ZeusIOPS SSDs.
There was no indication as to whether the Hitachi GST SSD is a single level cell (SLC) or multi-level cell (MLC) device.
