The nearby-future of storage

The ioDrive Duo by FusionIO out-performs even multiple SSD's placed in parallel. The 320GB version of the ioDrive has a read/write speed of ~1.5GB/s:

Difference with traditional SSD:

• The flash memory is integrated in the PCI card.
• The flash memory has been optimized using a proprietary technology.

Downside:

• Cannot be used as a boot drive.
• Requires a 64-bit operating system.
• The price is about 15,000 euro for 320GB version (ssdeurope.com). Ofcourse, this has to be compared against the cost of buying and operating a SAN.
