At a recent conference thematic Flash Memory Summit 2014 HGST company, which is a part of Western Digital, demonstrated a prototype of SSD . This development is quite different from anything that can now be found on sale. Different architecture, a different memory, a different interface protocol. Preserved only form factor and signal interface - PCI Express 2.0 x4. Development productivity, drawn from the 1-Gbit chips, reached 3 million IOPS when reading random 512-bit blocks. Latencies at random reading of about 1.5 microseconds. These rates several times better than in the case of possible to obtain SSD for NAND-type memory using the newest protocol NVM Express.
The company has created a SSD-based non-volatile memory with changing the phase state of matter (PCM, phase change memory). Excellent speed performance PCM memory repeatedly confirmed. In the latter case, for example, in May this year, IBM partners showed modular SSD based on 90nm memory PCM. In the prototype SSD HGST used 45nm memory. By the way, HGST company develops and manufactures serial SSD without Intel involvement , we can assume that the chip used in the storage PCM produced by Micron.
Finally, HGST company announced a new series SSD with PCI Express interface for flash memory NAND MLC - FlashMAX III. This server-class SSD performance 540,000 IOPS in 4K random read mode blocks with speed and 200,000 IOPS when accessing data in mixed mode (70/30 read / write). Interface - PCI Express 3.0. Deliveries SSD series FlashMAX III will start in the third quarter of this year.
