I like your Harddrives but why didn't you develop/produce SSD's for PCI-Express bus like OCZ's Revodrive but even better? For example protection plates to save the storage chips from static loads.
The botleneck of fast storage is the interface sata, sas, or even other regular storageinterface. If you could connect storage nearer to the frontsidebus (and PCI-express definitly is) the faster ist the transferrate. To day on sata, you can't get over 300mb/s but even on PCIe you get over 1gb/s.
