TechARP heard rumors that Western Digital is looking into hybrid HDDs that use DDR3 memory rather than flash memory:
Okay, none of this is confirmed but some of the stuff that the folks at Western Digital are looking into include RAM hybrid drives, built-in anti-virus protection, and data recovery warranty.
"Before you scoff at us for being so outdated, Western Digital is looking into a hybrid drive that uses RAM, not flash memory. This would most likely be a DDR3 SDRAM solution, possibly LP-DDR3 with backup power from built-in capacitors.
Such a hybrid drive would offer a tremendous boost in performance for HDDs, because RAM is many, many times faster than the fastest flash memory.
