How to enterprise grade PCIe SSDs compare to the speed of ramdisking?

RAMDisk is faster for large workloads, but you can't get as large a size as you can with a PCI-E SSD.

 

Enterprise PCI-E SSDs (from FusionIO and the like) are actually only slightly better than SATA SSDs in regular day-to-day stuff. They're incredibly fast in heavy workloads (think huge databases with hundreds of thousands of queries per second).

Most SATA SSD's normally cap out around 500-600 Mbs for Read and Write, but PCIe SSD's go all the up to 2800 Mbs or more.

Im actually building a gaming rig with the Intel P3700 series 400GB.

I'll tell how well it works in gaming and booting as soon as I can get my GPU's to finish the rig.
