I'm curious about using RamDisk to accelerate web browsing by placing the cache folders in it as many online have talked about.
I suspect though that many of them were using HDDs when they spoke of the performance benefits.
Does anyone know off-hand (or seen benchmarks, I couldn't find any) how a RamDisk would compare against an SSD? I run SSD in RAID10, so I'm also interested in comparing RamDisk vs that.
Intuitively, I feel as if it wouldn't make a large performance difference? I'm not esp. worried about wearing out the SSDs... since I suspect I'll get new hardware long before they start to slowdown... but I know that's one of the impetuses for using RamDisk...
A ramdisk would have approximatel 10x the speed and bandwidth of the SSD (in the 5-6GB range if you have DDR3). However you would need constant power to the Ramdisk - and if you run out of power you will lose everything located on the ramdisk.
Chainzsaw - thanks for the benchmarks! I suppose though I'd have to just test it both ways to see the differences - I have a feeling that, as mbryans is saying, even moving the browser cache to the RAM (compared with an SSD array in RAID10) will have a minimal improvement and will be limited more so by actual ISP provision rather than local caching.
