16GB for $1500? Uh... is it me, or is that still about 15-20x the $/GB of a recent 15KRPM SCSI drive? You can get latest-gen 146GB drives for maybe $700 each (about $5/GB), and older ones for less. 10KRPM Raptor 150GB SATA drives (nearly as good for single-user work) are only $300 ($2/GB). 16GB for $1500 is more like $90-100/GB.
Admittedly, there are situations where a sizable RAMDisk could make a big performance difference, but I'm not sure a lot of single-user workloads are in there.
I'm trying to figure out a good backup scheme for the ramdisk. One of my ideas involves using two 36gb Raptors and doing a nightly clone of the ramdisk and alternating which disk the backup is made to. However, if I get a virus, then it can still eat those backup drives. If I go USB or Firewire, the backup will be a lot slower, but I will get the ability to turn the backup drive on and off. Any good ideas would be appreciated
I would not rely entirely on 'internal' backups.
Besides the possibility of software/user error or OS failure or a virus corrupting your data, a system-wide hardware failure (like your PSU blowing up, or your disk controller going bad, or even a real 'disaster' like a fire or flood) could easily wreck all your internal drives at once.
