SATA 300MB/s and up to 8GB of DDR2

At Computex 2006 this year, Gigabyte is displaying the successor to its i-RAM storage device, the GC-RAMDISK. Gone is the PCI slot power interface and instead Gigabyte has made the GC-RAMDISK a 5.25” drive bay that relies on power from a Molex connector.

The Serial ATA interface remains with added compatibility for 300MB/s transfer rates, though it is unknown if the GC-RAMDISK will support SATA 3.0Gbps features such as native command queuing -- though with access times so low the only real advantage of the new feature set is the increased data transfer. DDR2 memory is supported this time around instead of DDR of the previous i-Ram. Supported memory capacity has been increased to up to 8GB from the previous 4GB which is just enough to make the i-Ram useful as an OS drive. Since DDR2 memory is not non-volatile (NAND), a battery feeds power to the memory when the system is off to prevent data loss.

As the GC-RAMDISK is still in development, availability is still a few months away. Pricing information is unavailable at this time but expect similar pricing to the previous i-Ram.

Molex Power?

One of the nice things about the PCI i-ram is that when you power off the pc, the 5v aux is still feeding the i-ram so you aren't using the battery. It only kicks in if you switch off your power supply/unplug/have a power outage. I am guessing that this will either run on a Molex or a SATA power connector. Does anyone know if these connectors will provide power even when the system is switched off?

No, there's no power at all on the standard molex connectors when power is off. All standby power goes to the mainboard through the 20/24-pin connector.

If they want standby power to support the RAM when the system is off, they'll have to find a way to tap a PCI slot, or the keyboard port, or in some cases USB. The problems there are that not all motherboards provide standby power to the keyboard port and/or USB ports; in some instances it's set by a jumper that defaults to off.

To add a little more, I suppose they could come up with a little plug adapter that sits between the main power cable and the power plug on the mainboard, and drop the needed power lines off that... such a thing is bound to be bulky and expensive though.

Perfect for a DIY project.

Or they could just release an AC/DC adaptor that you run through the back of your case to power the drive with.
