i-RAM as a boot drive

Since the i-RAM appears as a normal hard drive, you can install Windows on it just like you would a regular hard drive with no extra drivers (assuming that none are needed for your SATA controller).

A full install of Windows XP Pro can easily fit on a 4GB i-RAM and even on a 2GB i-RAM, but you have to be careful not to install applications into the C:\Program Files directory and disable System Restore for the i-RAM drive among other precautions. Why would you ever want to install your OS on an i-RAM card? We came up with two possibilities:

First off, loading your OS on the i-RAM will reduce boot times.

Boot Time Comparison
Windows Boot Time (Lower is Better)
Gigabyte i-RAM (4GB)
9.12s
Western Digital Raptor (74GB)
14.06s


With a Western Digital Raptor, you can go from the boot menu to the Windows desktop in 14.06 seconds; with the i-RAM, it takes 9.12 seconds. It's not instantaneous, but it's definitely quicker and noticeable.

Our thoughts are that with further optimization, the boot process can be better tuned for very low latency storage devices such as the i-RAM, but that won't happen with any currently shipping version of Windows.

The second reason for installing your OS on an i-RAM card is a bit more specific, but one we came up with when thinking about a secondary benefit of Gigabyte's i-RAM: it's silent.

You could theoretically build a home theater computer using just the i-RAM to hold your OS and map a network drive (hopefully kept in another room) to hold all of your media (e.g. music, movies, pictures, etc.). Paired with a silent PSU and a very quiet running CPU fan (maybe even on a Pentium M based system), you can have a truly silent HTPC, thanks to the i-RAM. You'd ideally want whatever database of your media collection to be stored on the network drive and not your OS, just in case something ever happened causing your i-RAM to lose its data, but it is a viable use for Gigabyte's i-RAM.

    That and/or having the possibility to install very large amounts of RAM (like 32GB) on your motherboard and BIOS settings to decide how much of that is non-volatile.

    I have a feeling this is a transitional product that while being a very nice add on to your current system, will become obsolete in 4 to 5 years. If I had to capture loads of high sampled audio (96/24), I'd want one now, though.

    I was expecting something closer to the $50 price mentioned at computex... It would have been a nice device to tinker around with, but at that price (plus the price of ram) I dont think most of us will get it.

    why they have to waste pci bus speeds and run though a sata chip beyound me it should directly conect to the pci bus have its own bois and run as full fleached ram or as normal ram with a redirect to being a hdd heack u have ram disk software idea the drive is pretty useless as permenment storage why no1 could see this i do not know
