World leading SSD Controller Technology

Mtron SSD has the world leading and patented SSD controller technology. The Hydra Architecture used in the SSD controller is made up of:

· Hydra Multiray
· Hyrda FTL
· Hydra Flash management

Hydra Multiray

The key approach of Hydra architecture is to maximize parallelism and thereby SSD performance by utilizing multiple control channels.

· Multi-Data Bus Array : 4 channel flash memory bus
· Multi-Flash chips Array: 4 way flash chip interleaving
· Multi-Data streams: Simultaneous processing of multiple data streams
· Multi-Flash control: Priority-based scheduling for foreground & background flash memory access

Hydra FTL

Hydra FTL (Flash Translation Layer) translates data read and write requests from the computer to the SSD. It analyses requested commands, maps addresses between logical sector numbers and physical flash memory locations, and handles data transfer to/from the flash memory.

· Interleaving: Efficiently utilizes hardware automation for maximum interleaving effect
· Logical block allocation: Use small logical block to achieve maximum efficiency
· Address mapping: Efficient check-point policy for address mapping and recovery

Hydra Flash Management

The Hydra Flash Management is made up of the following three technologies to achieve the highest reliability and data integrity.

· Wear Leveling Technology

Each single flash memory cell has a limited number of write. Mtron's dynamic and static wear-leveling technology spreads data evenly across the whole drive so that the lifspan of all cells are extended. As a result, the Hydra Flash Management algorithm can extend the lifespan of a 32GB SSD to 140 years even when it repeatedly writing and deleting 50GB per day.

· Bad Block Management

Flash memory may develop new bad blocks during normal use. The Mtron Hydra Flash Management algorithm efficiently detects these new bad blocks and substitutes them with reserved blocks and eliminate any errors due to bad blocks to ensure data integrity.

· 7bit ECC (Error Correction Code)

Mtron SSD employs 7bit ECC per 512bytes to correct any possible data failures. It offers higher product reliability than the 2bit or 4bit ECC other SSD makers are using.
