There doesn't seem to be anything here on ramdrives such as the gigabyte gc or the hyperos hyperdrive5. Does anyone here have any experiences with such devices? are the performance boosts worth the price? Is data corruption a comon problem? I imagine using ram for even just temp files would greatly increase speed. And if you could "guarantee" power failure would not be an issue, would having all system/os files really be a great improvement? I've thought it might for a while, before I knew this kind of hardware existed. I dreamed of raided ramdisks.Its also fun to say. But does anyone have any real experiences ?

Ram still operates much faster than flash/SSD's though.

true but you are not limited to 4gb.

The 4gb limit is the option provided by Gigabyte. The Acard supports 32 gb, the hyperdrive5 provides a capacity of 64gb. Both more than enough storage space for all system files. I

System on RAM?

That's riding the bleeding edge as far as I can see.

You can be the 'Point Man' for us, just let us know how it works for you.

Ive used a Maxell audio cassette tape as a live disk. I have a wireless rotary phone. I run a an old honda cb200 motorcycle off of 9v batteries. If you are looking for something that "is, but shouldn't be" I am your guy.

I used to like to tinker with stuff a lot when I was younger and had lot's of time on my hands. You grow out of it eventually,....Smile

RAM Drives(in the newer sense of the word, as apposed to DOS) is NOT worth the price.

It is extremely expensive plus you need a battery backup at any time the computer is not running. This makes it that much more likely for you to lose your data.

RAM was designed to be FAST and not care about errors. Most error checking it done by the CPU and calls back to the ram when an error occors to get the right stuff.

So you have to have ECC ram when you run a RAM drive or you will have problems.

ECC ram is also very expensive, and very rare, and typically slower than standard RAM.

It adds an extra cycle or 2 to the process to slow things down even more.

RAM is not as realiable as NAND Flash as well.

There are many negatives, and the only positive... is that it's fast.

You would be better off buying a $500 RAID card and running 8 really Fast SSDs in a RAID 0. This will get you to 2GB/s of read performance.... do you really need any more than that?
