IBM's optical storage is 50 times faster than flash
Flash storage is too slow for your device's main memory, but RAM is expensive and volatile. Thanks to a breakthrough from IBM, phase-change memory (PCM) might one day replace them both. The crystal-based storage has been used in optical disks and other tech for at least 15 years, but the technology has been limited by the cost and storage density -- cells are either "on" or "off." However, IBM researchers have figured out how to save 3-bits of data per cell, dramatically increasing the capacity of the original tech.
Samsung wants to kill hard drives with new high-efficiency SSDs
For the first time, Samsung has starting producing SSDs using (wait for it) 3-bit multi-level-cell, 3D Vertical NAND flash memory, better known as TLC V-NAND. So, who in the actual hell cares? You might, if you're planning on buying an SSD or computer soon. Samsung's current V-NAND technology has resulted in models like the 850 Pro SSD, which topped all benchmarks and has a 10-year guarantee. But combining V-NAND with 3-bit tech has more than doubled wafer yields, which should result in even cheaper, faster and higher-capacity SSDs. The disks aren't on sale yet, but there's a good chance that one of the first available will be Samsung's recently leaked 850 EVO.
SanDisk makes 128-gigabit flash chip, crams three bits per cell, takes afternoon off
SanDisk has developed a chip that earns it membership in the exclusive 128-gigabit club. Not content with simply matching the Micron / Intel effort, SanDisk and its partner Toshiba claim their new memory uses 19- rather than 20-nanometer cells in the production process. Shrinking the size is one thing, but SanDisk's new chips also use its X3 / three-bit technology. Most memory stores just two bits per cell; cramming in another means fewer cells, less silicon, more savings, cheaper memory, happier geeks. Analyst Jim Handy estimates that the price per gigabyte for the tri-bit breed of flash could be as low as 28 cents, compared to 35 for the Micron / Intel equivalent. Full details in the not-so-compact press release after the break.
