Ram Disk anyone?

Getting 4530MB/s

Here's a very similar example on one of my machines.

It doesn't have much ram, but this old MMO game gets very stuttery when logging 'raid' activity, so I allocated just a 128MB ramdisk to it to avoid that. After my gaming sessions, I delete or archive off anything useful left over in the ramdisk.

The left half of the screen shows the Disk Management setup, the right half shows how it looks from a Windows Explorer point of view. It's not so bad to setup.

I had a a play around with Dataram's Ramdisk, yesterday.

I am currently working on a computer program, which requires oodles of processing power and fast/short file write/reads.

I've created a benchmarking program which puts my program to the limit.
The Ramdisk certainly does make the program run faster and offers, the fastest benchmark times. The write/read times also put SSDs to shame.

I was looking in to getting 16GB of RAM, instead of using an SSD, last night, but 16GB of RAM is prohibitively expensive right now, so this looks like a no go. I think 16GB of DDR3 ram is costing over £150 - for that money I can buy a 128GB SSD.

All my development shall now take place from within the Ramdisk now. the Ramdisk utility saves an image of the ramdisk every 5 minutes, so at worst, I shall only lose 5 minutes of work.

One thing that has not been mentioned so far is the dreaded blue screen of death. If you get one of those, no UPS will save your data.

I didn't even know this was possible. Very cool.

Hi

I have been considering using a ramdisk to improve smoothness/streaming of textures within Arma 2.

However i only have 4gb of ram on my system, is it still worth me doing ? if so what size should i make my ram disk ?

What I have noticed is that RAMDISKS, although super fast - some programs rely on accessing your main OS drive. If this OS drive is a mechanical drive, then your load times are no better.

The best thing to do is experiment. How big are the texture files, within arma 2?

Has anybody seen the RAM-SAN? The name kinda speaks for itself.http://www.ramsan.com/products/4

basically a ramdisk of DDR2 , with SSD for backup. The price must be outrageous. But I'd buy one^H^H^H two when I win the lotto.
