The folks at Akiba PC Hotline! have spotted a new 2.5" 80GB hybrid hard drive from a company called Mcell. Whereas hybrid hard drives typically come with 128MB or 256MB buffers made up of NAND flash memory, this model has a 1GB buffer that's made up of DDR system memory.
According to Mcell—as quoted by Akiba—this 1GB DDR buffer enables transfer speeds above 110MB/s in random read tests for data sizes of 64KB to 512MB. The drive uses a 150MB/s Serial ATA interface, weighs in at 500g (1.1lbs), and Akiba has snapped pictures of it on sale for a relatively affordable ¥15,800 ($136.50).Mcell, Hard Disk, HDD, Hardware, Storage, 80GB hybrid hard drive, NAND, Flash Memory, RAM
