ram-based drives

post #1 of 2
Thread Starter 
Are there any relatively modern pci boards that accept memory sticks and maintain state via battery that work as solid state storage? If not and they're all flash based, why has this technology never caught on? It's superior in speed to flash and even with old memory sticks is infinitely quicker, and it can use raid with a mechanical disk for backup, yes?

They're out there, but they're all enterprise solutions. Not something you're going to find on Newegg.

It didn't catch on because it's power hungry and expensive, and requires either batteries or a line to the PSU's standby rail to keep data when the system is turned off. It was still considered a viable competitor to NAND SSDs up until around 2008, when there were major drops in the cost of NAND memory. With its lower power consumption and no need for batteries NAND appealed more to the enterprise sector, and the lower cost made it more appealing to general consumers (or enthusiasts at least).


DRAM SSDs are now a rare niche product.
