RAM Disk

[ccd1]

This is for all you Linux users.

How many of you use RAM disc? For those of you that don't know, it's something that grabs a portion of your RAM and treats it like your hard drive (which makes it super-fast).

Any draw backs to it?

any data on the ramdrive will be lost when the machine powers off

yeah if the machine shuts down the info on the ramdrive is gone..

i used a ramdrive on winxp pro for a while but if i crashed and had to reboot i lost the data... so ended up moving it back onto disk :rolleyes:

I've kind of fixed this for myself though,
every minute, the data on the ramdisk is copied back to HD.

i suppose it would be possible to write a small daemon with filesystem hooks, noticing if a file changes (and if it does, copy it to a alternate location)

on reboot, the latest copied version is restored onto the ramdrive

[eva2000]

yeah the ramdrive software i used in winxp has manual backup to disk function :rolleyes:

cant you just use shadowing and every time the computer boots the files you need are transferred to the RAM?

I have mine setup for certain temp files.
Not all system temp's are written there :) We do not want to encourage corruption. It helps a little on those old servers with lame hd's and specs.
